Agenda item 1.1: Requests from administrations to delete their country footnotes or to have their country name deleted from footnotes, if no longer required, in accordance with Resolution 26 (Rev. WRC-97)

Issue

Footnotes form an integral part of the Table of Frequency Allocations (Article 5) in the ITU-R Radio Regulations (RR). Footnotes are adopted by competent world radio conferences and any addition, modification or deletion of a footnote is considered and adopted by the competent conference. Footnotes in the Table of Frequency Allocations should be clear, concise and understandable. They should relate directly to matters of frequency allocations rather dealing with the operation of stations, assignment of frequencies or other matters. The Table of Frequency Allocations should include only those footnotes which have international implications for the use of the radio-frequency spectrum. Footnotes have to be kept updated.

Preliminary CEPT position

CEPT supports administrations taking the initiative to review their footnotes and to propose the deletion of their country names or the deletion of country footnotes, if no longer required.

Background

The examination of footnotes as expressed in agenda item 1.1 is a standing item on the agenda of WRCs. This item only comprises the deletion of country footnotes or country names from footnotes. However, proposals for new footnotes or modifications of existing footnotes could exceptionally be considered by a WRC under special circumstances. With regard to a global harmonisation of spectrum usage footnotes referring to national issues should be avoided.

Actions to be taken

In line with the agenda item 1.1 the CEPT administrations should critically examine their country footnotes in the view whether they are still necessary in the existing form and to propose the deletion of their country footnotes or of their country names from footnotes, as appropriate.

In order to support this activity WG FM has asked the ERO to provide it for every CEPT member country with a list of those country footnotes which are not mentioned in the ECA (Report 25) under the column ‘European Common Allocation’.An analysis of the current “country-footnotes” was distributed to Administrations 13 November 2001 for detailed consideration. The ERO has received initial information from 10 Administrations indicating intend to delete their country name from a footnote or providing editorial mistakes regarding their particular country in the analysis.

The following administrations have provided information so far:

AustriaDenmarkEstoniaHungaryIcelandItalyPolandRussian FederationSlovak RepublicSlovenia

Annex 1 provides the current status of participation in country footnotes with indications of countries which have indicated intent to delete their country name.

(The information will be updated as further indications from administrations are received)

Agenda item 1.2: To review and take action, as required, on No. S5.134 and related Resolutions 517 (Rev.WRC-97) and 537 (WRC-97) and Recommendations 515 (Rev.WRC-97), 517 (HFBC-87), 519 (WARC-92) and Appendix S11, in the light of the studies and actions set out therein, having particular regard to the advancement of new modulation techniques, including digital techniques, capable of providing an optimum balance between sound quality, bandwidth and circuit reliability in the use of the HF bands allocated to the broadcasting service

IssueThe introduction of new modulation techniques is essential to the continued improvement and development of the HF broadcasting service and requires a number of coordinated actions to bring the technical regulations governing the use of and access to the HF bands allocated to the broadcasting service in line with the latest technological developments.

Preliminary CEPT positionEuropean industry and broadcasters have been spearheading the development and testing of new digital technology for use in the short, medium and long wave bands. Europe supports the comprehensive review of the regulatory and technical material referenced in the agenda item and any associated actions to advance the introduction of digital HF broadcasting.Specific action is required in four main areas: Revise regulatory provisions to define a transition to digital modulation instead of the

replacement of DSB by SSB.Resolution 517 (Rev.WRC-97): Revise so as to refer to the 3 modulation systems accepted for HFBC, which will be contained in the revised Appendix S11, and to direct a transition to digital modulation only (alternatively, this point could be the subject of a new Resolution).The 3 accepted modulation systems for HFBC scheduling and planning will be:

DSBSSB –6dBITU-R BS.1514 Annex 1

NB: This implies that SSB –12dB would not be a permitted form of operation and will require the current references in Part B of Appendix S11 and Recommendation 517 (HFBC-87).Resolution 537 (WRC-97): Suppress, since all useful actions complete by WRC-2003Recommendation 515 (Rev.WRC-97): Incorporate useful actions into Resolution 517 (Rev.WRC-03) and suppress.Recommendation 519 (WARC-92): Suppress, since proposed actions no longer viable and Resolution 517 (Rev.WRC-03) will govern the further technical development of HF broadcasting.Appendix S11: Revise to include system parameters and other necessary information appropriate to digital broadcasting in the HF bands. The material relevant to the SSB –12dB system should be removed. Initially, however, the existing material on system parameters for SSB –6dB system will be maintained since the agenda item does not imply that broadcasting using SSB should be discontinued entirely. However, proposals from outside CEPT to eliminate references to SSB completely need not be resisted.

Provide the necessary information on protection ratios applicable to the recommended types of modulation

11


Update information on protection ratios to include digital modulation systems as necessary to condition service planning. The material could be incorporated into Resolution 517 (Rev.WRC-03), Recommendation 517, a new WRC Recommendation or a new ITU-R Recommendation. Alternatively the material could be incorporated into Appendix S11 directly. The final preference will depend on the timing and scope of the conclusions of ITU-R TG6/7.Remove material relevant to the SSB –12dB system from Recommendation 517.

Date of cessation of DSB services The expectation is that the objective of a transition to digitally modulated emissions will be achieved as a result of a natural progression matching the pace of regional demand. A switch-off date for analogue HFBC services is therefore no longer required and Resolution 517 should be revised accordingly. However, to encourage the transition, a date of [I January 2004] should be set by which all new HF broadcasting transmitters will have the capability to offer digital modulation. Again this aim could be achieved by modifications to Resolution 517.

The WARC-92 extension bands and the use of digital modulation systems in the broadcasting service Significant use of parts of the WARC-92 extension bands by the fixed and mobile services is expected to continue until the 1 April 2007 access date for the broadcasting service. Therefore no changes should be introduced to permit earlier access by the broadcasting service. Editorial changes to footnote S5.134 are, however, required to reflect the fact that no significant use of single-sideband emissions is envisaged, and that the future competent conference referred to is actually WRC-2003.The permitted modulation schemes for HF broadcasting will be those refernced in Appendix S11 (as modified by WRC-2003). It is further envisaged that the majority of HF broadcasting services will use the digital modulation system described in Recommendation ITU-R BS.1514. The technical parameters required for the introduction of the digital systems, such as RF Protection Ratios, are proposed to be included in new Recommendation [YYY] (WRC-03), to be referred to in Resolution 517 (Rev. WRC-03).

BackgroundGeneral

Efforts to improve the quality and reliability of HF broadcasting have been made at various times over the last 25 years. However there was never any complete or enthusiastic agreement on the path to take. Much of this effort was concentrated on planning for a transition from DSB to SSB, for which the main rationale was the need to ease pressure on the spectrum available for HF broadcasting and transmitter power requirements. Whether sound quality would be improved by the transition to SSB was not the main driving force, and this lack of emphasis on a very important aspect of broadcasting proved to be a major impediment to the widespread acceptance of SSB as an alternative to DSB. While some improvements in audibility were expected because of reduced congestion in a totally SSB environment, the technique does not offer any demonstrable improvement inherent in the modulation technique itself. Furthermore, when SSB –6dB compatible transmitters were tested, it became clear that the efficiency gains in spectrum use were only half those expected, transmitter power savings were fairly meagre.

The almost inevitable result has been very limited progress towards replacing DSB broadcasting services at HF with SSB, even though the final cessation date was intended to be 2015. The slow rate of progress was highlighted at WRC-2000 in the Director’s Report on experiences in the application of the Radio Regulatory Procedures and other related matters

12


(Document CMR2000/15). This was the direct result of the advice from WRC-97 that the first survey of transmitter and receiver statistics called for in Resolution 517 (Rev.WRC-97) should be conducted as a matter of urgency and in time for the next Conference. The Director reported the following conclusions, which were based mainly on a broadcast receiver and transmitter survey carried out by Working Party 10A of ITU-R Study Group 10:

No SSB receiver equipped with a synchronous demodulator has been identified in the price range up to USD 200. Even in the price range from 200 to USD 600, only 15% of the HF receiver models identified are equipped with a synchronous detector.

It is not known what percentage of the estimated 500 to 700 million HF receivers in the world are capable of SSB reception and have a synchronous detector.

It is estimated that between 11 and 22% of the HF transmitters in the world are already capable of carrying SSB signals.

It is further estimated that between 9 and 14% of the HF transmitters in the world are already capable of being converted to carrying SSB signals.

It is probable that most HF transmitters which can carry SSB signals, could also carry digital signals. However this assumption will need to be confirmed when the details of an ITU-R recommended digital AM system are available.

Several countries expressed dissatisfaction with the intended transition to SSB during WRC-95 and by the time of WRC-97 it was becoming clear that digital modulation technologies could offer dramatic improvements in sound quality at HF. A further advantage foreseen was that the characteristics of the technologies under study were such that reliable network coverage should be achievable using fewer simultaneous frequencies per target area.

With the expectation that improvements in quality, reliability and spectrum use would be possible, the mood of WRC-97 was to shift the goal on future HF broadcasting technology towards digital modulation rather than SSB. As a result, Resolution 517 (Rev.WRC-97), which is the main instrument governing the introduction of new technology for HF broadcasting, was revised comprehensively at WRC-97 with the objective of eventually phasing out DSB in favour of new digital modulation techniques. At that time it was not possible to predict the precise form of a new recommended technology or what transition time could be appropriate.Transition to digitally modulated emissions

There has been significant progress in the development of digital modulation schemes since WRC-97, when Resolution 517 was revised to encourage the development and introduction of new modulation techniques. ITU-R Study Group 6 has developed a new Recommendation BS.1514 which provides system description of digital modulation to replace or supplement DSB transmissions in the LF, MF and HF sound broadcasting bands.

Although the main thrust of the work to further encourage the introduction of digital modulation for HF broadcasting has to be a further revision of Resolution 517, many other parts of the Radio Regulations are involved1. Appendix S11 is also relevant.

The Report of the Director of the Radiocommunication Bureau to WRC-2000 reviewing WARC/WRC Resolutions and Recommendations (Document CMR2000/15) records that the Resolutions and Recommendations related to HF broadcasting are either under active study or have become partially or wholly obsolete.

WRC-2000 accepted that a comprehensive review of all this material was both necessary, because of rapid progress on digital technology, and overdue, because of the redundant nature of much of the material still in force. The complicated linkages between these 1 the regulatory material relating to HF broadcasting involves six WRC Resolutions and Recommendations as well as Article S12 and Appendix S11.

13


Recommendations and Resolutions meant that the resulting agenda item for WRC-2003 had to allow for a comprehensive review of Resolution 517 (Rev.WRC-97) and all the associated technical material in the Radio Regulations.

Activities in ITU-RAt its meeting in March 2001, WP6E produced an preliminary set of views (document Annex 9 to Document 6E/93) on agenda item 1.2. With the exception of those on No. S5.134, these views are closely aligned to preliminary CEPT position.

PART [1.2]

Agenda Item 1.2 - New modulation techniques in HFBC

WRC-2003 agenda item 1.2 - “to review and take action, as required, on No. S5.134 and related Resolutions 517 (Rev.WRC-97) and 537 (WRC-97) and Recommendations 515 (Rev.WRC-97), 517 (HFBC-87), 519 (WARC-92) and Appendix S11, in the light of the studies and actions set out therein, having particular regard to the advancement of new modulation techniques, including digital techniques, capable of providing an optimum balance between sound quality, bandwidth and circuit reliability in the use of the HF bands allocated to the broadcasting service;”

IntroductionThis item is directed towards the introduction of digital modulation techniques for broadcasting in the HF bands. ITU-R Study Group 6, has determined that the modulation techniques to be considered under this agenda item may be limited to just the digital modulation techniques recommended in Recommendation ITU-R BS.1514. WRC-2003 is therefore fully competent to establish the necessary conditions for introducing digitally modulated emissions to the HF bands allocated to broadcasting using those techniques. The following changes to the Radio Regulations will serve to satisfy the agenda item:

Administrations are urged to use these bands to facilitate the introduction of digitally modulated emissions in accordance with the provisions of Resolution 517 (Rev. WRC-2003).

Reasons:The purpose of the modification is to promote the use of digital modulation techniques for broadcasting and to clarify the conditions of access to the bands by the broadcasting service.1. suitable modulation techniques are now defined in Recommendation ITU-R BS.1514;2. Appendix S11, as proposed for revision in EUR/1.2/3 & EUR/1.2/4, includes the

appropriate system specifications; and3. Resolution 517 (Rev. WRC-2003), as proposed in EUR /1.2/8, provides the necessary

technical parameters allowing the introduction of digital modulation techniques.

However, in order to protect existing use of these bands by the fixed and certain mobile services until the envisaged implementation date for the WARC-92 extension bands for HF broadcasting, the bands will only become available to the broadcasting service from 1 April 2007. The access date of 1 April 2007 date corresponds to the end of the primary allocation of these bands to fixed or mobile services, as mentioned in Nos S5.136, S5.143, S5.146, and S5.151. And this provides the reasonably smooth transition necessary for these current services to find other bands which to move to in accordance with Resolution 21 (Rev.WRC-95).Because the only conferences currently planned prior to the 2007 implementation date are WRC-03 and WRC-05/6, this revision deletes reference to the decisions of a future competent conference. WRC-03 is fully competent to determine the implementation date as it chooses, in accordance with agenda item 1.2. Any other changes that might be considered at WRC-05/6 would be unlikely to come into force before 1 April 2007.

System specifications for Double-Sideband (DSB), Single-Sideband (SSB) and Digitally Modulated Emissions in the HF Broadcasting Service

NOC EUR/1.2/3

PART A – Double-sideband (DSB) system

MOD EUR/1.2/4

PART B – Single-sideband (SSB) system

1 System parameters

1.1 Channel spacingIn a mixed DSB, SSB and Digital environment (see Resolution 517 (Rev. WRC-03 )), the channel spacing shall be 10 kHz. In the interest of spectrum conservation, it is also permissible to interleave SSB emissions midway between two adjacent DSB channels, i.e., with 5 kHz separation between carrier frequencies, provided that the interleaved emission is not to the same geographical area as either of the emissions between which it is interleaved.In an all inclusive SSB environment, the channel spacing and carrier frequency separation shall be 5 kHz.

1.2 Equivalent sideband powerWhen the carrier reduction relative to peak envelope power is 6 dB, an equivalent SSB emission is one giving the same audio-frequency signal-to-noise ratio at the receiver output as the corresponding DSB emission, when it is received by a DSB receiver with envelope detection. This is achieved when the sideband power of the SSB emission is 3 dB larger than

16


the total sideband power of the DSB emission. (The peak envelope power of the equivalent SSB emission and the carrier power are the same as that of the DSB emission.)

2 Emission characteristics

2.1 Nominal carrier frequenciesNominal carrier frequencies shall be integral multiples of 5 kHz.

2.2 Frequency toleranceThe frequency tolerance shall be 10 Hz.2

2.3 Audio-frequency bandThe upper limit of the audio-frequency band (at – 3 dB) of the transmitter shall not exceed 4.5 kHz with a further slope of attenuation of 35 dB/kHz and the lower limit shall be 150 Hz with lower frequencies attenuated at a slope of 6 dB per octave.

2.4 Modulation processingIf audio-frequency signal processing is used, the dynamic range of the modulating signal shall be not less than 20 dB.

2.5 Necessary bandwidthThe necessary bandwidth shall not exceed 4.5 kHz.

2.6 Carrier reduction (relative to peak envelope power)In a mixed DSB, SSB and Digital environment the carrier reduction shall be 6 dB to allow SSB emissions to be received by conventional DSB receivers with envelope detection without significant deterioration of the reception quality.

2.7 Sideband to be emittedOnly the upper sideband shall be used.

2.8 Attenuation of the unwanted sidebandThe attenuation of the unwanted sideband (lower sideband) and of intermodulation products in that part of the emission spectrum shall be at least 35 dB relative to the wanted sideband signal level. However, since there is in practice a large difference between signal amplitudes in adjacent channels, a greater attenuation is recommended.

3 Characteristics of the reference receiverThe reference receiver has the main characteristics as given below. For more detailed characteristics see the relevant ITU-R Recommendations.

3.1 Noise limited sensitivityThe value of the noise limited sensitivity is equal to or less than 40 dB(V/m).

3.2 Demodulator and carrier acquisitionThe reference receiver is equipped with a synchronous demodulator, using for the carrier acquisition a device which regenerates a carrier by means of a suitable control loop which locks the receiver to the incoming carrier. The reference receiver should work as well with

2 See Note 21) of Appendix 2.17


DSB emissions as with SSB emissions having a carrier reduced to 6 dB below peak envelope power.

3.3 Overall selectivityThe reference receiver has an overall bandwidth (at – 3 dB) of 4 kHz, with a slope of attenuation of 35 dB/kHz.

NOTE - Other combinations of bandwidth and slope of attenuation are possible, as given below, and will provide the same performance at 5 kHz carrier difference.

ADD EUR/1.2/5

PART C – Digital system1 System parameters

1.1 Channel spacingThe initial spacing for digitally modulated emissions use shall be 10 kHz. However, interleaved channels with a separation of 5 kHz may be used in accordance with the appropriate protection criteria appearing in Recommendation YYY (WRC-03), provided that the interleaved emission is not to the same geographical area as either of the emissions between which it is interleaved.

1.2 Channel utilisationChannels using digitally modulated emissions may be commingled with analogue emissions in the same HFBC band provided the protection to the analogue emissions is at least as great as that which currently is in force with analogue-to-analogue protection. To Draft ECP on Agenda Item 1.2 Source: ANNEX 4 to CEPT/ECC/CPG03(2002) 07

accomplish this may require that the digital spectral power density (and total power) be lower by several dB than is currently used for the same emission circuit using either DSB or SSB emissions.

2 Emission characteristics

2.1 Bandwidth and centre frequencyA full digitally modulated emission will have a 10 kHz bandwidth with its centre frequency at any of the 5 kHz possibilities within the HFBC bands.There are “simulcast” modes, which are a combination of analogue and digital emissions of the same programme in the same channel, that may use a digital emission of 5 kHz or 10 kHz bandwidth, next to either a 5 kHz or 10 kHz analogue emission. In all cases of this type, the 5 kHz interleaved raster used in HFBC shall be adhered to in placing the emission within the HFBC bands.

2.2 Frequency tolerance

[To be determined.]18


2.3 Audio frequency bandDigital source coding within a 10 kHz bandwidth, taking account of the need for various levels of error avoidance, detection and correction coding emission mitigation, can range from the equivalent of monophonic FM (approximately 15 kHz) to low level speech codec performance of the order of 3 kHz. The choice of audio quality is connected to the needs of the broadcaster/listener, and includes such characteristics to consider as the propagation channel conditions expected. There is no single specification, only the upper and lower bounds noted in this paragraph.

2.4 ModulationQuadrature amplitude modulation (QAM) with Orthogonal frequency division multiplexing (OFDM) shall be used. 64 QAM is feasible under many propagation conditions; factors of ½, ¼ and perhaps 1/8 of this are specified for use when needed.

Introduction of single-sideband (SSB) emissions and possible advancement of the date for cessation of the

use of double-sideband (DSB) emissions in the HF bands allocated to the broadcasting service

Reasons: There is concern within many Administrations, expressed on many occasions at WRC-97, that the introduction of SSB into HF Broadcasting should not restrict the ability of administrations to continue with their existing DSB transmissions for the foreseeable future and that at this point in time it is inappropriate to specify a cessation of DSB in favour of SSB in the year 2015. It is also evident from information presented at WRC-2000 by the Director that the interest in SSB within HF Broadcasting is virtually non-existent. This Recommendation should therefore be suppressed.

1 Narrowband systems3: Support the identification of the bands 380-385 MHz / 390-395 MHz on a global basis for narrowband systems

2 Wideband systems1: [TBD]3 Broadband systems1: [TBD]

Currently there is no CEPT position yet on the frequency requirements and ranges for the wideband and broadband systems. Preliminary possible candidate frequency ranges have been identified by ITU-R WP8A and reviewed by WG FM; a summary of WG FM comments is in annex 1 to this document, detailed comments can be found in a separate information document. CEPT position is depending on the further studies on the spectrum calculation methodology. FM PT38 is willing to offer its expertise on these ongoing studies for wideband and broadband systems, if the CPG agrees. This work could continue until the deadline of WRC-03 inputs. At that point of time the CPG should reconsider, if ECP’s could be developed for wideband and broadband systems, or if the proposal of the CEPT would be to have a Resolution in WRC-03 supporting further studies until WRC-06.

Initial CEPT views on spectrum requirements

Narrowband:

** The frequency bands 380-385 MHz and 390-395 MHz for the use by digital land mobile systems as designated for emergency services by the CEPT Decision ERC/DEC/(96)01. Digital narrow band systems are already taken into use or will be taken into use in near future. A draft ECP has been developed.

Wideband:

3 Narrow band systems are using channels up to 25 kHz, wide band systems up to 200 kHz and broadband systems more than 200 kHz.

27


** Based on the method mentioned in section B2 it is estimated that [5-12 MHz] is required within the identified frequency ranges in order to accommodate wideband applications based on a [50-200] kHz channel raster plan. Standardisation of digital wide band systems is ongoing and digital wide band systems could be available in 2002-2003.

Broadband:

** Based on the method mentioned in section B2 it is estimated that [50 up to 200 MHz] is required within the identified frequency ranges. The studies on Broadband techniques have recently started and systems are envisaged in a longer term than for narrow band and wide band systems.

Background

A) General informationA1) WRC-2000 recognised the benefits of globally harmonised frequency bands for public protection and disaster relief and also recognised an increasing need for the interoperability and inter-working between security and emergency networks, both nationally and for cross-border operations, in emergency situations and disaster relief.

In principle, all services, terrestrial or satellite services, could support radiocommunications in order to satisfy Agenda Item 1.3 of Resolution 800 (WRC-2000) on a global or regional bases.

The CEPT paid similar recognition to the utilisation of frequency band for emergency services, which led to the adoption of ERC/DEC/(96)01. This Decision designates the frequency bands 380-385 MHz and 390-395 MHz for the use by digital land mobile systems for emergency services.

In addition, some CEPT countries also utilise, based on bilateral agreements, especially selected frequency bands for cross-border disaster relief and emergency services, i.e. for cases of nuclear power plant malfunctions.

ITU-R WP8A is the responsible Working Party for Agenda Item 1.3 of Resolution 800 (WRC-2000). WP 8A sent out a questionnaire in order to assess the current activities, future plans and intentions with regard to public protection and disaster relief communications. A summary of the responses can be found in doc.8A/56 also as FM38 (2001)28.

A2) In WP8A the following definitions have been preliminary agreed

Public protection communicationsCommunications used by responsible agencies and organizations dealing with maintenance of law and order, safety of life and property, and emergency situations.

Disaster relief communicationsCommunications used by agencies and organizations dealing with a serious disruption of the functioning of society, posing a significant, widespread threat to human life, health, property or the environment, whether caused by accident, nature or human activity, and whether developing suddenly or as a result of complex, long-term processes.

28


Systems will include the deployment of special units for voice, data and image/video transfer.

A3) Current public protection and disaster relief activities were identified together with the frequency bands in use and the technical and operational issues facing providers of public protection and disaster relief communications including factors constraining the use of radio communications.

From the survey, it was determined that most public protection and disaster relief communications at present are dependent upon the use of narrowband analogue technologies and the introduction of narrowband digital technologies was noted. The survey revealed the range of operational conditions placed on current public protection and disaster relief communications and the types of organizations that provide these communications.

The development of public protection and disaster relief communications involving narrowband, wideband and broadband technologies4 was analysed based on national plans. The responses also identified frequency bands in which a degree of regional harmonisation has already been achieved for current public protection and disaster relief communications.General support was indicated in the responses for a resolution on cross-border circulation of public protection and disaster relief communications equipment. Now that this support has been established, work remains in WP8A/WG3 to determine the appropriate technical and operational parameters for inclusion in such a resolution.

At the WP8A meeting in October 2001, on the basis of WP8A/WG3 outcome, it became apparent that future advanced applications are likely to flow from the availability of wideband and broadband technologies as complementing, not replacing the current or shortly planned digital narrowband systems.

It has also to be noted that ETSI and TIA have founded together in the “Public Safety Partnership Project”, now known as Mobility for Emergency and Safety Applications (MESA) project, to develop standards primarily addressed to broad band solutions. In MESA the Service Specifications Group is currently studying the services and applications and after the outcome of this group is approved, the Technical Specification Groups will start their work.

The information emerging from both ITU-R WP8A and the MESA (PSPP) may be very relevant to considerations for identification of harmonised bands.

B) Operational user requirements and spectrum requirements

B1) Operational user requirementsAt the WP8A meeting in October 2001 an extensive exercise resulted to an agreed list of applications and system requirements. WG FM has reviewed and slightly improved this list and it can be found in a separate information document (see Doc. CPG(02)XXX).

Some of the most critical technical and operational characteristics of PPDR networks include:

Network to be fully controlled by PPDR agencies i.e. instant/dynamic reconfiguration changes (set-up talk groups; priority levels on channels, groups or general calls;

4

29


spectrum resource availability for multiple PPDR agencies coordination; re-routing; etc.)

Group call, repeater and Direct Mode Operation (DMO) capability (simplex radio and push-to-talk)

High quality of service: vital fast call set-up & instant push to talk, resilience under extreme load, very high call set up success rate, etc.

Guaranteed access including priority and pre-emption calls Security i.e. end to end encryption, terminals/network authentication etc. High reliability (e.g. redundancy on emergency operations, prompt capacity increase,

human safety of personnel, etc. ) Customised & reliable coverage, especially indoor(e.g. underground and inaccessible

areas) These characteristics include the management of the frequency resources and of the quality of service by a fast flexible organisation.

Preliminary scenarios

The collected information by WP8A/WG3 shows indications about several simultaneous wideband -broadband applications running in parallel putting a huge demand (very high bit rates) on the wireless system operating in a “hot spot” that refers to a deployment of systems in certain areas where public protection and disaster relief personnel operate.An example may be High-resolution Video surveillance of security entry points such as airports with automatic detection based on reference images, hazardous material or other relevant parameters; another case is the remote monitoring of patients and remote real time video view of the single patient demanding up to 1 Mb/s. The demand for capacity can easily be envisioned during the rescue operation following a major disaster. This means about a net hot spot capacity of over 100 Mb/s.

It seems that the foreseen vision is an integration of today known systems (i.e. narrowband technology based) complementing each other with those of wideband and broadband. In this concept, wideband systems would have similar coverage requirements as narrowband systems, that is, emergency providers may expect coverage over their entire area of operation. Broadband systems, however, are more likely to be more localised in coverage at an incident or near a hot spot. - Therefore a possible way forward for broadband appears to be the use of a quite high frequency spectrum, compared to that of today’s dispatch land mobile common approach.This is because the new services fundamentally means:

- High data rate- Hot-spot areas (i.e. pico-cells structure alike)- High Frequency re-use factor

The frequencies should be chosen with careful consideration to difficult propagation conditions for disaster relief applications (e.g. multipath effect in collapsed buildings).

While public safety agencies will continue to use commercial systems for their non-tactical and administrative needs, for the mission-critical needs there maybe different requirements These differences may drive a growing demand for systems specifically designed with facilities such as dispatch, encryption, guaranteed access, and physical security of command centres, of public safety agencies in the future.

30


It should be noted that ITU WP8F is analysing WP8A PPDR systems requirements and will provide WP8A information on the capabilities of IMT-2000 and in which extent it complies with requirements.

B2) Calculation methodology for spectrum requirements:

WP 8A/WG3:WP8A/WG3 elaborated a first working document towards a preliminary draft new recommendation (PDNR) on a methodology for calculating spectrum requirements for public protection and disaster relief communications. (See doc. 8AWG3/TEMP13(Rev1), 8AWG3/38 and 8A/TEMP/50 also as FM38(2001)29, FM38(2001)27 and FM38(2001)68, respectively).ctrum calculation methodology. This methodology for calculating spectrum requirements is following an approach similar to that used for IMT-2000 (ITU-R Recommendation M.1390). The ITU-R M.1390 was based on a generic method that can be used to calculate the spectrum requirements for any land mobile services delivering communications via a combination of voice and data circuits. When the M.1390 methodology was used for PPDR services a list of 15-example PPDR voice & data services and their parameters were defined, for IMT-2000 a list of 5 voice and data services to compute spectrum requirements was used. At the WP 8A meeting in October 2001 further consolidation on the spectrum calculation methodology was achieved based on a new revised version as provided by Motorola. Some administrations also provided inputs based on calculations they had made by using own national actual data. Based on these results WP8A has more confidence on the use of this methodology. However, further activities are still required at the WP8A/WG3 meeting in February 2002, where the final version of such a methodology is expected.

WG FM Within CEPT, the PT FM38 has studied the Spectrum Calculation Methodology and has noted that input parameters are critical in arriving at a sensible estimation of spectrum requirements. In the Spectrum Calculation Methodology there are a number of factors which can either be held constant or varied. Appropriate choice of these parameters needs to be made with extreme care. For a typical city, the cell radius modelled needs to be within approximately 2 and 7km for narrowband and 1.4 and 5km for wideband. Outside these ranges, the model produces less valid results.

The model allows systems to be dimensioned within constraints e.g. spectrum availability, area spectral efficiency of PPDR radio systems (b/s/Hz/m2) which includes cell size and technology. Overall, it is not easy to say whether the methodology at the present stage is appropriate for calculating PPDR spectrum requirements, however, using parameters from known systems produces results that correlate closely with reality.

Concerns were raised whether the Spectrum Calculation Methodology is appropriate to determine the spectrum requirements. However it was also recognised that at the moment there isn’t any alternative Calculation Methodology than as currently under study.The CPG agreed that FM38 continues its work on this issue also by following the developments in ITU-R WP8A. In particular it is desirable to evaluate it further by applying it to other known systems, so that bounds can be established for which the model is shown to give realistic results given reasonable input parameter values for PPDR applications.

ANNEX 1

List of candidate bands

Introduction

ITU-R WP8A has identified possible candidate bands for PPDR (document 8A/TEMP/62 of 26th October 2001). WG FM has reviewed these bands taking into account the requirements for narrowband, wideband and broadband systems. The list of candidate bands with WG FM comments can be found in a separate information document.

The categories as follows have been used for a preliminary judgement:

Categories: "1" (preferred)"2" (possible, further studies necessary)"3" (not possible)

The "category 2 bands" are bands, which would be feasible from a technical point of view, but the availability for PPDR purposes within CEPT has to be considered.

The table below summarizes the results:

Agenda item 1.4 : To consider the results of studies related to Resolution 114 (WRC-95), dealing with the use of the band 5091-5150 MHz by the Fixed-Satellite Service (Earth-to-Space) (limited to feeder links of the non-geostationary Mobile-Satellite Service), and review the allocation to the aeronautical radionavigation service and the fixed-satellite service in the frequency band 5091-5150 MHz

Issue

Revision of the allocations in the band 5091-5150 MHz


If the need for future MLS or other ARNS application is confirmed, to keep the balance of resolution 114, ie operation of ARNS and FSS feeder links can continue on a shared basis subject to a review in XXXX.

If the need for MLS or other ARNS application is not confirmed, to modify resolution 114 and footnote S5.444A in order to allocate FSS (limited to NGSO MSS feeder links) primary in the 5091 – 5150 MHz frequency band with no more subject to review.

To require study of the impact to existing services in this band before adding any new allocation of services other than FSS and ARNS in this band.

Background

WRC-95, by the means of Resolution 114, resolved: "that the allocation to the aeronautical radionavigation service and the fixed-satellite service in the frequency band 5091-5150 MHz should be reviewed at the 2001 World Radiocommunication Conference" and required ITU-R "to study the technical and operational issues relating to sharing of this band between the aeronautical radionavigation service and the fixed-satellite service providing feeder links of the non-geostationary mobile-satellite service (Earth-to-space)" and "to bring the results of these studies to the attention of WRC-2001."

In accordance with resolves 1 of Res.114, ICAO has developed a procedure to establish the spectrum requirements for MLS and other potential aeronautical applications, in order to support the future allocation requirement for the band 5 091 - 5 150 MHz. The results should be available around end 2001. This procedure includes:

- update of the MLS requirements by States;- review of the operational requirements of MLS (Ref. Annex 10, Volume I Radio

Navigation Aids);- replanning of MLS assignments to establish spectrum requirements;- identification of future spectrum requirements for other aeronautical systems;- presentation and discussion of results in ICAO; and- presentation of results to ITU.

35


Resolution 114 also recognised that the fixed-satellite service providing feeder links for non-geostationary mobile-satellite services will need access to the frequency band 5091 - 5150 MHz at least until 2010, in order to accommodate identified and future requirements. Considering footnote S5.444A, it is possible to make new assignments to feeder links for non-geostationary mobile-satellite services in the FSS until 31/12/2007.

The band 5091 - 5150 MHz is currently used by stations operating in the fixed-satellite service to provide feeder links for non-geostationary mobile-satellite services. In order to ensure a complete coverage of its service area, at least one implemented MSS system needs the use of the whole 5091-5250 MHz band. Actually the lack of any frequency channel in the feeder uplink will prevent the transmission of the corresponding beam in the service downlink and therefore will restrict dramatically the operation of this MSS system. WP 8D expects that if the two MSS systems currently operating gateway stations develop as planned, then the number of gateway stations implemented worldwide will be approximately 65. Therefore changing feeder link assignments below 5150 MHz is neither expected nor feasible in frequencies above 5150 MHz.

ITU-R WP 8D has developed elements for draft CPM text stating that no interference has been encountered by MLS stations from FSS earth stations for NGSO MSS feeder links so far. This draft text was sent to the ITU-R WP 8B as a liaison statement (Doc 8B/50). The responsible group within ITU-R is WP8B and has requested Administrations to provide operational studies to indicate to what extent MSS feeder links have used spectrum to-date in the range 5091-5150 MHz (Doc 8B/100 Attachment 9).

ITU-R WP8B has proposed CPM text to use this frequency bands for new aviation applications like Airport network and location equipment (ANLE)(document 9B/TEMP 37 of May 2001 which are not part of the Aeronautical RadioNavigation Service and would require an additional allocation

Agenda item 1.5: To consider, in accordance with Resolution 736 (WRC-2000), regulatory provisions and spectrum requirements for new and additional allocations to the mobile, fixed, Earth exploration-satellite and space research services, and to review the status of the radiolocation service in the frequency range 5 150–5 725 MHz, with a view to updating it, taking into account the results of ITU-R studies

Issue

This agenda item covers the following issues:

1. allocation of frequencies to the mobile service in the bands 5 150-5 350 MHz and 5 470-5 725 MHz for the implementation of wireless access systems including RLANs;

2. a possible allocation in Region 3 to the fixed service in the band 5 250-5 350 MHz, while fully protecting the worldwide Earth exploration-satellite (active) and space research (active) services;

3. additional primary allocations for the Earth exploration-satellite service (active) and space research service (active) in the frequency range 5 460-5 570 MHz;

4. a review, with a view to upgrading, of the status of frequency allocations to the radiolocation service in the frequency range 5 350-5 650 MHz.


1. Proposal for new primary allocations to the mobile service in the bands 5 150-5 350 and 5 470-5 725 MHz for wireless access systems including RLANs ensuring the implementation of mitigation techniques in accordance with ERC Decision (ERC/DEC/(99)23) (see table 1)

2. Ensure protection of the Earth exploration satellite (active) and space research services in the band 5 250-5 350 MHz. The allocation to the fixed service in Region 3 should not prevent the worldwide primary allocation to the mobile service as proposed under point 1.

3. Support of additional primary allocations to EESS (active) and SRS (active) in the frequency range 5 460-5 570 MHz subject to no additional constrains to the worldwide primary allocation to the mobile service as proposed under point 1;

4. [Additional secondary allocation to EESS (active) limited to radar altimeter in the frequency range 5 140 – 5 250 MHz; The CEPT proposal for the band 5150 – 5250 MHz (see item 1) is linked to the outcome for WRC 2003 Agenda item 1.6]

5. Upgrade of the status of frequency allocations to the radiolocation service in the frequency range 5 350-5 650 MHz. In the band 5 470-5 650 MHz the upgrade is seen as a consequence to a worldwide primary allocation to the mobile service as proposed under point 1.

37


Background

1. Mobile service (RLANs) in the bands 5 150 – 5 350 and 5 470 – 5 725 MHz

To gain global harmonised frequency allocations to the mobile service in support of wireless access systems including RLANs, on a world-wide basis, while ensuring the protection and on-going operations of existing services a world-wide primary allocation to the mobile service is targeted in the frequency ranges 5 150-5 350 MHz and 5 470-5 725 MHz.

There is already an additional Mobile Service allocation in the band 5 150–5 250 MHz for Europe and a number of other countries through the footnote S5.447 in the Radio Regulations. The band 5 150-5 350 MHz is already nationally used for RLAN in many countries and the global MS allocation would give wireless access systems including RLANs an appropriate ITU allocation status.

Work in Europe has been progressing for some time on wireless LAN applications supporting advanced features. In 1992 such requirements were anticipated in ERC Recommendation T/R 22-06 under the acronym HIPERLANs and subsequently in the European Common Allocation (ECA) table developed as a result of the DSI process with allocations at 5 GHz and 17 GHz. ETSI has adopted standards for equipment that will use the 5 GHz allocation and is developing further standards.

With the global growth in mobile internet and multi-media applications the use of RLAN technology has enormous potential worldwide. Europe has shown its strong support through ERC Decision ERC/DEC(99)23 and allocations in the European Common Allocation Table.

ETSI and CEPT have calculated that 330 MHz spectrum is required for RLANs to fulfil the expected traffic demands. In support of this WG FM and WG SE have been carrying out studies to identify suitable frequency bands for further expansion of RLANs in the 5 GHz range. Based on the studies, the frequency bands 5 150–5 350 MHz and 5 470–5 725 MHz have been designated for RLANs. The compatibility studies within CEPT on sharing between RLANs and existing services at 5 GHz band proved that sharing is feasible under certain conditions (ERC Report 072) (see table 1).

JRG 8A-9B started to develop a Preliminary Draft New Recommendation on a methodology for assessing the required spectrum for wireless access systems (including RLANs). Based on this Recommendation a ITU-R Report on 5 GHz spectrum requirements for the mobile service for wireless access systems including RLANs will be produced.

On ITU-R level the work on sharing studies are also completed for the MSS feeder links. JRG 8A-9B cooperates with WP7C towards the development of an M-series ITU-R Recommendation specifying an e.i.r.p. limit and operational restrictions for RLANs in the band 5 250-5 350 MHz to protect the EESS (active). The Preliminary Draft New Recommendation is based on sharing analysis for typical spaceborne active sensors. The European views on the implementation of mitigation techniques as TPC and DFS are reflected in the Recommendation. However, at the JRG 8A-9B meeting in March 2001 Canada and the US proposed a similar recommendation for RLANs with directional antenna.. The technical and operational characteristics are quite different from those envisaged in Europe. At the following meeting in October 2001 it was agreed to merge both recommendations to one Preliminary Draft New Recommendation for all wireless access systems including RLANs.However, even if the PDNR could not be accepted before WRC-

38


03, it is evident that sufficient sharing conditions can be arranged e.g. with restrictions stated in ERC/DEC/(99)23.

Sharing studies between the mobile service (RLAN) and the EESS (active) in the band 5 470 – 5 570 MHz are in progress within WP 7C and JRG 8A-9B.

In the other key areas, i.e. radiolocation/navigation work has just started in WP 8B and JRG 8A-9B. The first results show that RLAN systems are affected by radar systems at far greater distance than the point where radar suffers interference from the RLAN. Therefore RLANs will have to use mitigation techniques (e.g. DFS) to avoid channels used by radars. The development of a Preliminary Draft New Recommendation on Dynamic Frequency Selection for RLANs operating in the 5 GHz band just started at the October meeting of JRG 8A-9B.

Good progress was made in the JRG proposal for draft CPM text. Different methods to fulfil agenda item 1.5 resolves 1 were introduced. The responsible group within ITU-R to develop the CPM-text is JTG 4-7-8-9. JTG 4-7-8-9 will have its last meeting 30 th April – 8th May 2002 in Geneva.

Typical indoor RLANs have a cell radius of 30 m or less. Outdoor systems have a larger cell radius of typically 3 to 4 times the indoor cell radius. RLANs fall into the ITU-R categories Nomadic Wireless Access or Mobile Wireless Access. RLANs are usually deployed in geographically limited areas. RLAN should have a comparable performance to a stationary wired LAN.

2. Fixed service (Fixed Wireless Access) in Region 3 in the band 5 250 – 5 350 MHz

There is a requirement for FWA systems in the 5 250-5 350 MHz band in Region 3, as proposed by Japan, to provide high speed Internet access. It should be noted that this application has a significant impact on the sharing situation. The feasibility of sharing of mobile services in this band is dependent on an indoor use restriction and a usage pattern consistent with ad-hoc networking. FWA systems have neither of these features.

Japan presented sharing studies between FWA and EESS at the JTG 4-7-8-9 meeting 4-8 June 2001 in Cleveland. These studies were approved by JRG 8A-9B. The PDNR has been sent to WP 7C for further comments. Administrative measures for base and remote stations, such as license-based operation, would be required in order to control deployment density of FWA systems to guarantee compatibility.

PDNR ITU-R f.[FWA5GHZ-eess] “Operational and deployment restrictions for fixed wireless access (FWA) systems in the fixed service in Region 3 to ensure the protection of systems in the Earth exploration-satellite service (active) and the space research service (active) in the band 5 250-5 350 MHz” states that,it is difficult for RLAN and FWA to share the same frequency at the same location. RLANs would need to be operated outside FWA cells, if they use the same frequency as FWA. Even if RLANs are operated within FWA cells, most of them would use frequency channels different from the FWA system in the end due to RLAN's CSMA/CD and DFS capabilities. Thus, FWA and RLAN do not cause interference to EESS satellites simultaneously at the same frequency from the same spot.

39


Further discussions on the sharing situation between RLAN and FWA within JRG 8A-9B are needed. The above mentioned PDNR text should be modified to reflect the correct sharing situation between RLAN and FWA.

Sharing studies between FWA and radiolocation systems were submitted at the October 2001 meeting of JRG 8A-9B and WP 8B.The interference from the radar into the FWA receiver will be higher than the other direction in terms of level. The protection of the radar operation need to be confirmed by administrative procedures.

3. Earth Exploration Satellite (active) and Space Research (active) Services in the band 5 460–5 570 MHz

The proposal for an additional allocation for EESS (active) and Space Research (active) in the band 5 460–5 570 MHz is intended to permit the operation of satellite sensors at increased resolution.

There is a need for compatibility studies between this proposal and the proposal for a MOBILE allocation in the overlapping area 5 470-5 570 MHz. This is part of the band identified for out-door 1 Watt RLAN operation in Europe and and the same operating condition should be possible, if the EESS allocation is accepted.

Within Europe, the main interest in this allocation is for measurements over oceans and rural areas and so the parallel proposals for EESS and Mobile allocations may not conflict. However, taking account of the other types of sensor, global acceptance of the European RLAN arrangements may be difficult.

At the PT SE 36 in March 2001 a Contribution has been submitted proposing to investigate an additional primary allocation of 110 MHz to EESS (active) in the band 5 140-5 250 MHz to complement of 5 460 – 5 570 MHz as originally proposed by Resolution 736 for the use of space radar altimeters. At its June meeting in Cleveland Ohio JTG 4-7-8-9 decided not to include this proposal in the CPM text until the relevant ITU-R groups will support the French proposal.

Subsequently, the proposal has been modified into a request for a secondary allocation in the 5140-5250 MHz band for EESS (active) restricted to altimeters. New sharing studies have been presented to JPT5G and are to be submitted to ITU-R.

In the WG FM meeting in January 2002, there was no support for the proposal, neither was there any outright objection. However, a few administrations expressed concerns about the impact of such an allocation to the existing services, in particular with aeronautical radionavigation (MLS) in the band 5140 – 5150 MHz band and MSS feeder links in the whole band.

Concerns were expressed by one administration about pursuing this issue, who considers the issue to be outside the scope of the agenda for WRC 2003, since the effort required to promote this issue may be at the expense of the other CEPT objectives under Agenda item 1.5.

However, WG FM agreed that there must be no adverse impact on CEPTs plans for a primary mobile allocation to support RLANs.

40


The existing studies presented to JPT5G, together with new studies, need to be completed to clarify these issues.

Compatibility studies between EESS/SRS (active) and RLANs in the band 5 470- 5 570 MHz have still to be undertaken.

In case of an additional allocation for EESS (active) and space research (active) in the band 5460-5570 MHz, it has been proposed to extend the application of footnote n° S 5.448B up to 5570 since the sharing situation between EESS and the radionavigation service is identical below and above 5460 MHz.

4. Radiolocation service in the band 5 350-5 650 MHz

The proposed upgrade of the Radiolocation service to primary is based on studies completed in the ITU-R, which demonstrate the compatibility with the existing primary services. The upgrade of the status in the frequency band 5 470 – 5 650 MHz is seen as a consequence to a worldwide primary allocation to the mobile service as envisaged in resolves 1.

No specific footnote is required which would make any constraints on the development and deployment of both the radiolocation service and the Earth exploration-satellite service (active) in the band 5 350-5 570 MHz.

In addition, it has been proposed that, as a consequence of the sharing situation in the band 5 350-5 570 MHz between the EESS (active) and the radiolocation service, the deletion of footnote S5.448A could be considered. This proposal seems to have been agreed by WP8B. On the contrary, on this specific issue of footnote, it has been proposed, that the status-quo for the EESS bands below 5460 MHz would probably be the most appropriate solution, which means that the footnote S5.448A should remain as it is. Further decision on this issue is needed.

Actions to be taken

CEPT needs to promote the European studies and frequency arrangements for these bands within the relevant ITU-R groups and CEPT members will need to participate in the relevant ITU-R groups, to ensure the work is progressed efficiently..

CEPT needs to complete studies for dealing with the conflicting proposals from the EESS/SRS (active) and RLAN communities for the band 5 470-5 570 MHz.

Europe will need to address the compatibility issues raised by other RLAN systems, which share the same physical layer with HIPERLAN/2. In particular IEEE 802.11a which currently does not include the minimum requirements for co-existence in the band, i.e. DFS, TPC. These European requirements will be implemented by the development of IEEE 802.11h.

CEPT to take a position on the additional secondary allocation in the band 5 140 – 5 250 MHz to the EESS (active) limited to radar altimeters.

Agenda Item 1.6 : To consider regulatory measures to protect feeder links (Earth-to-space) for the mobile-satellite service which operate in the band 5 150-5 250 MHz, taking into account the latest ITU-R Recommendations (for example, Recommendations ITU-R S.1426, ITU-R S.427 and ITU-R M.1454)

Issue

This agenda item addresses the provision of regulatory measures to protect MSS feeder links operating in the band 5150-5250 MHz, in view of the possible new allocation to the mobile service in this band for RLAN applications.

Preliminary CEPT Position

The CEPT wishes to see the following regulatory measures implemented which will allow the successful introduction of mobile applications in this band, whilst ensuring the protection of the MSS feeder links :1. the transmission limits and indoor usage restrictions for RLANs contained in

Recommendation ITU-R M.1454 should be inserted in the Radio Regulations;2. [measures to ensure protection of MSS feeder links from potential aggregate interference

effects of RLANs.]

Background

[Editorial note: this text is to be updated as the work progresses]

MSS feeder links operate in the band 5150 – 5250 MHz under the primary allocation to the Fixed Satellite Service (Earth to space). The band is shared on a co-primary basis with the Aeronautical Radionavigation service, originally intended for the Microwave Landing System (MLS). However, MSS feeder links were introduced with the understanding that the band is not needed for MLS and hence Aeronautical Radionavigation is not addressed within WRC 2003 Agenda item 1.6.

This band had been first designated in Europe for HIPERLAN use in 1992 in CEPT Recommendation T/R 22-06 (later superseded by ERC Recommendation CEPT/REC/REC 70-03 and ERC Decision ERC/DEC/(96)03). However, following the allocation of the band 5150 - 5250 MHz to Fixed Satellite Service Feeder links for the Mobile Satellite Service at WRC-95; concern was expressed over the use of this band for mobile applications.

It should be noted that S5.447 allocates the mobile service in the band 5150 - 5250 MHz in a number of CEPT countries, subject to agreement obtained under S9.21. Although this agreement has never been completed, WG FM has stated that HIPERLAN should be regarded as co-primary with MSS feeder links in Europe.

Studies carried out by project team SE28 led to the development of ERC Report 67. The results of the SE28 studies, considered by the WG SE/FM Joint Task Group on HIPERLAN together with the SE24H report, led to the reduction of the maximum permitted power level for HIPERLAN from 1 W to 200 mW and an indoor only use restriction. These measures intended to protect the MSS feeder links were included in ERC Decision ERC/DEC/(99)23,

48


together with additional spectrum as identified by SE24H. It should be noted that a review process is built into this ERC Decision.

This issue was studied in ITU-R by JRG 8A-9B and WP4A leading to the development of Recommendations M.1454, S.1426 and S.1427 defining the operational restrictions for RLANs, protection criteria of the MSS feeder links and methodology and criterion to assess the interference respectively. Although there are some differences in the definition of permitted power levels for RLANs in Recommendation M.1454, the sharing arrangements defined by ITU-R are consistent with those developed in CEPT.

Recommendations in Recommendation ITU-R M.1454:1) administrations should ensure that the mean e.i.r.p. density limit of RLAN or other

wireless access transmitter devices operating in the band 5 150-5 250 MHz should be no greater than 10 mW in any 1 MHz (or equivalently 0.04 mW in any 4 kHz) per transmitter (Notes 1, 2 and 3);

2) administrations should take measures to ensure that RLAN or other wireless access transmitters are operated indoors in the bands 5 150-5 250 MHz;

3) for the protection of MSS feeder links, power flux-density (pfd) limit of total RLAN interference observed at the victim satellite receiver, for satellites using full earth coverage antennas, should be no greater than the pfd levels specified in Recommendation ITU-R S.1426. A lower pfd level should be used as a trigger for administrations to take actions to protect non-GSO MSS feeder links from aggregate RLAN interference (Notes 4 and 5);

4) administrations should consider implementation of mitigation techniques to further reduce interference into FSS systems from RLANs (see Note 6).

Note 4 details recommends 3, proposing, on a provisional basis, a pfd trigger level 3 dB below that in draft new Recommendation ITU-R S.1426, further study being required.

Recommendations in Recommendation ITU-R S.1426:1) RLANs sharing the same frequency bands with non-GSO feeder links in the FSS

should be designed in such a manner that their aggregate RLAN power flux-density be limited to–148 20 log10(hSAT/1 414) dB(W/(m2 · 4 kHz)), at the FSS satellite orbit for spacecraft using full earth coverage receive antennas and where hSAT is the altitude of the satellite (km).

Note 1 details the meaning of the term "aggregate": the interference to the satellite receiving beam is to be calculated from all of the RLANs within the field of view of the non-GSO satellite receiving beam.Note 2 indicates the need of further studies for non-GSO spacecraft with multiple narrow spot beams.

Recommendations in Recommendation. ITU-R S.1427:1) the assessment of interference from RLAN emissions to non-GSO MSS satellite

feeder-link receivers, operating in the band 5 150-5 250 MHz, should be based on the increase (Tsatellite) in satellite noise temperature (Tsatellite);

2) in order to ensure the adequate protection for the non-GSO MSS feeder links from RLAN emissions in the band 5 150-5 250 MHz the aggregate Tsatellite/Tsatellite should be no more than 3%.

49


Note 1 indicates the need for further studies to evaluate the impact of long term interference due to RLANs into the non-GSO MSS feeder links in terms of the reduction in non-GSO MSS system capacity, and sets a provisional tolerable reduction in capacity of 1%.Note 2 details the meaning of the term "aggregate": the interference to the satellite receiving beam is to be calculated from all of the RLANs within the field of view of the non-GSO satellite feeder link receiving beam.

It should be noted that Study Group 3 has expressed the opinion that that there is higher building shielding attenuation than previously considered, this may be regarded as giving an additional 'safety margin' in the results. JRG 8A-9B is of the opinion that this provides and additional 5 dB protection for the MSS feeder links, whilst WP4A considers the original value to be appropriate. Further advice is expected from WP3M.

Work is underway within JPT5G on the ways to satisfy agenda item 1.6 taking account of ITU-R Recommendations M.1454, S.1426 and S.1427. Concerning Recommendation S.1426, two issues to be resolved have been identified :

- How to determine the interference level affecting the MSS system (calculation or measurement);

- What action to take when the interference approaches an unacceptable level.

Preliminary conclusions indicate that although there are technical difficulties in measuring the aggregate interference level at the satellite, and the 'neutrality' of such a measurement could be questioned if it is made by the MSS operators, measurement still represents the most likely solution.

JPT5G will consider a proposed measurement method under development with WP4A, with a view to contributing on this issue in future.

JPT5G does not believe it is feasible to determine the number of RLANs in use and calculate the interference level. However, if the 'trigger point' were reached this would require a huge number of RLANs to be in use and it is expected that there would be a general awareness of the situation

With respect to the action to be taken, JPT5G agree that the chosen means should not set any threat to the availability of the band to either of the systems. The band is assigned to both MSS feeder links and RLANs with an equal status in Europe.

JPT5G agree that if the density of RLANs were to reach the trigger level, then this would represent a success of RLANs and very significant demand for spectrum which would justify a re-examination of the allocations.

The initial thoughts of SE36 on this issue were that WRC 2003 Agenda item 1.6 could be satisfied by including text in the Radio Regulations so that if the interference trigger level is reached, the issue is identified for resolution as an urgent matter by the next WRC. It is necessary to decide whether to proceed with this idea, and if so develop a proposal to WP4A.

At present, WP4A has developed draft CPM text which addresses four possible methods to satisfy Agenda Item 1.6: Solution 1: No change in the Radio Regulations if the three ITU-R Recommendations are

felt to be sufficient for the sharing between the two services.

Solution 2: insert the transmission limits and indoor usage restrictions (ITU-R M.1454) on the RLANs in the Radio Regulations.

50


Solution 3: in addition to solution 2, refer also to the pfd limit of ITU-R S.1426 in the Radio Regulation, and possibly also to a lower ‘trigger level’, i.e. setting an interference trigger level at the satellite orbit.

Solution 4: in addition to solution 2, include other pfd limits in the Radio Regulation.

In addition, there are two possible implementations to incorporate solutions 2 or 3 above. The first implementation is incorporation of the relevant material directly in the Radio Regulations and the second method is incorporation by reference.

It should be noted that Solution 1 is not actually preferred by any administration, however it is necessary to include it for completeness.

Action to be taken in preparation for WRC-2003

CEPT needs to develop a view on the regulatory procedures which would satisfy this agenda item and promote this view within WP4A.

Agenda item 1.8 : to consider issues related to unwanted emissions

Agenda item 1.8.1 : consideration of the results of studies regarding the boundary between spurious and out-of-band emissions, with a view to including the boundary in Appendix S3;

1. IssueMatters related to unwanted emissions.

2. Preliminary CEPT PositionThe CEPT adopted the principle of variation of the boundary as described in draft new Recommendation ITU-R on “Variation of the Boundary between the Out-of-band and Spurious Domain” developed by TG 1-5. CEPT supports the proposed modification of Article S1 and the modification of Appendix S3 either by providing specific exceptions from the general 2.5Bn boundary based on the Recommendation ITU-R SM.1539 and Recommendation ITU-R SM.1541 or by including by reference all or part of those two recommendations. CEPT does not support the proposed method 3 because of the missing mandatory reference to Recommendation ITU–R SM.1539.

3. BackgroundIn July 2001, Study Group 1 has approved a package of new or revised Recommendations dealing with unwanted emissions:– Recommendation ITU-R SM.329-9, “Spurious Emissions” provides limits for the unwanted emissions falling in the Spurious Domain.– Recommendation ITU–R SM.1541, “Unwanted Emission in the Out-of-Band Domain" provides limits for the unwanted emissions falling in the Out-of-band Domain.– Recommendation ITU-R SM.1539, “Variation of the Boundary between the Out-of-Band and Spurious Domains required for the application of Recommendation ITU-R SM.1541 and SM.329” contains the result of TG 1/5 studies on the variations of the boundary between the out-of-band and spurious domains.It is important to note that these modifications in Recommendation ITU–R SM.329 and the new ITU–R SM.1539 have changed neither the unwanted emissions limits contained in ITU–R SM.329 and ITU–R SM.1541 nor the location of the boundary between the out-of-band and spurious domains.

With a view to completing the work on Agenda Item 1.8.1, Study Group 1 has established a Rapporteur’s Group to prepare input text for CPM-02. The output of the Rapporteur’s Group has been approved during the November 2001 meeting of Study Group 1. The proposals in the draft CPM text are :

a) to modify the Article S1, adding the definitions of out–of–band and spurious domain.b) to specify the out–of–band/spurious boundary in Appendix S3 following either :

– method 1 : Provide specific exceptions from the general 2.5Bn boundary for narrow-band systems, wideband systems, and other specific cases based on the Recommendation ITU-R SM.1539 and Recommendation ITU-R SM.1541.

– method 2 : Provide all or part of the boundary exceptions by reference to Recommendation ITU-R SM.1539 and Recommendation ITU-R SM.1541.

– method 3 : Provide only the current exceptions from the general 2.5Bn boundary between the out-of-band and spurious domains, being guided by Recommendation ITU-R SM.1539.

52


4. Actions to be TakenCEPT to support the modifications of Article S1 and the modification of Appendix S3 as described in the method 1 or 2 of the draft CPM text.It is understood in SE21 that USA and CEPT have the same approach on that Agenda Item and therefore that a common action may be envisaged before the next CPM.

Agenda item 1.8.2 : Consideration of the results of studies, and proposal of any regulatory measures regarding the protection of passive services from unwanted emissions, in particular from space service transmissions, in response to recommends 5 and 6 of Recommendation 66 (Rev.WRC-2000)

IssueRecommendation 66 (Rev.WRC-2000): Studies of the maximum permitted levels of unwanted emissions.Recommends 5 and 6 of Recommendation 66 call for studies of those frequency bands and instances where, for technical or operational reasons,

- more stringent spurious emission limits than the general limits in Appendix S3 (recommends 5) and

- out-of band limits (recommends 6)may be required to protect safety services and passive services such as radio astronomy, and the impact on all concerned services of implementing or not implementing such limits.

Preliminary CEPT positionTo support the necessary studies in response to recommends 5 and 6 of Recommendation 66 in order to protect the passive services to the utmost possible .

To participate actively in the responsible ITU-R TG 1/7 by contributing band-by-band studies which take into account the protection requirements of safety and passive services on one side and the technical means of active services, in particular but not exclusively space services, on the other side.

.

BackgroundThe studies of the maximum permitted levels of unwanted emissions as requested by Recommendation 66 were carried out by former ITU-R TG 1/3 and TG 1/5. In July 2001, a package of four new or revised Recommendations dealing with unwanted emissions was adopted. – Recommendation ITU-R SM.329-9, “Spurious Emissions”.– Recommendation ITU-R SM.1539, “Variation of the Boundary between the Out-of-Band and Spurious Domains required for the application of Recommendation ITU-R SM.1541 and ITU–R SM.329".– Recommendation ITU-R SM.1541, “Unwanted Emission in the Out-of-Band Domain".– Recommendation ITU-R SM.1540, “Unwanted Emissions in the Out-of-Band Domain falling into adjacent allocated bands”.

Regarding the protection of Passive and Safety Services from Unwanted Emissions the following Recommendations were also approved:– Recommendation ITU-R SM.1542 “The Protection of Passive Services from unwanted emissions”.– Recommendation ITU-R SM.1535 “The Protection of Safety Services from unwanted emissions”.

54


While the four Recommendations on unwanted emissions fulfil most of the requirements of Recommendation 66 concerning limits for spurious-, out-of-band emissions and the boundary between spurious- and out-of-band emissions the requested studies on recommends 5 and 6 of Rec.66 could not be finished by TG 1/5 in its final meeting. Study Group 1 therefore decided to establish a new TG 1/7 concerning the protection on passive service bands from unwanted emissions. A Working document which includes the relevant frequency bands for the protection of the passive services for the band-by-band studies was prepared by TG 1/5 and is used by the new TG 1/7 for the outstanding work.

CEPT has presented to TG1/7 a draft CPM text proposing the inclusion of RAS protection criteria given in Recommendation RA.769, "Protection criteria used for radioastronomical measurements" within the RR. A revised version of the CPM text was presented by USA in the 3rd meeting of TG 1/7. CEPT accepted the structure of this new proposal and added its views in the draft text. Further work has to be done in the 4th meeting in March 2002.At this meeting, the group will need to focus on finalizing the draft CPM text so as to meet the completion date of May 2002 even if the BbB studies will not be completed. The group will therefore have to progress the studies in the cases under consideration with the intention of finalizing the current PDNR SM.[band-by-band] for the Study Group 1 meeting in July 2002.

Some significant progress was made during the 3rd meeting of TG1/7 on the PDNR [BbB].The draft CPM text which was controversialy discussed before that meeting was completely reviewed to reflect the different options. At the moment the draft CPM text include five methods to address the Agenda Item 1.8.2. Advantages and disadvantages for active and passive services are explained in detail and need to be summarised in March.

Agenda item 1.14 : to consider measures to address harmful interference in the bands allocated to the maritime mobile and aeronautical mobile (R) services, taking into account Resolutions 207 (Rev. WRC-2000) and 350 (WRC-2000), and to review the frequency and channel arrangements in the maritime MF and HF bands concerning the use of new digital technology, also taking into account Resolution 347 (WRC-97).

Issues

1. Protection of frequencies allocated to maritime mobile and aeronautical (R) services from harmful interference (Resolution 207, rev. WRC2000).

2. The decision of WRC2000 specifying the frequencies 12 290 kHz and 16 420 kHz as exclusive use for distress and safety communications (Resolution 350 (WRC2000)).

3. Review of the channel arrangements in the maritime MF and HF bands for use of digital communications and new digital technology (Resolution 347 WRC97).

Preliminary CEPT positions

1. CEPT should support the proposals intending to protect aeronautical mobile (R) and maritime mobile services from interferences.

2. CEPT should carefully consider any proposals seeking to abrogate or postpone the WRC2000 decision making the frequencies 12290 kHz and 16420 kHz exclusive for distress and safety communications. These considerations should also take due account of the results of ITU studies undertaken as a consequence of the deliberations surrounding that decision.[CEPT should propose retention of the decisions of WRC 2000 on this matter, but adding a new resolution permitting MRCC’s to use these two frequencies for limited general calling for safety related communications, subject to certain safeguards.]

56


3. CEPT should support the development and the introduction of digital technology to supplement or replace existing analogue technology in the maritime MF and HF bands.Consideration should also be given to making provisions for the testing and introduction of digital technology. At the same time retaining the bands 1605 – 27 500kHz for existing Morse telegraphy (ie relevant parts of article S52 and of APPS17).

Consideration should be given to the deletion of those items of the Radio Regulations dealing with Morse telegraphy in the bands between 1605 and 27500 kHz (i.e. relevant parts of Article S52 and of App S17) and making a provision for the use of the existing Morse telegraphy frequencies for digital transmissions.

Background

Issue 1

WRC2000 discussed the problems of unauthorized transmissions causing harmful interference to the maritime mobile and aeronautical mobile (R) services in the HF and MF bands allocated to these services. In order assist in alleviating the problems encountered, WRC2000 expanded Resolution 207 in order to- urge administrations to make every effort to prevent unauthorized transmissions in these

bands and to ensure cessation of such transmissions;- invite ITU-R and ITU-D to

- study possible technical and regulatory solutions to assist in the mitigation of such interference;- increase the regional awareness of appropriate practices in order to help mitigate

interference in the HF bands;- continue to organize monitoring programmes in order to identify the stations operating in

these bands.

The Radiocommunication Bureau has in co-operation with administrations initiated new monitoring programmes aimed at identification of unauthorized transmissions in the HF bands allocated exclusively to the maritime and aeronautical mobile (R) services.

CEPT should monitor the progress and any outcome of the monitoring programmes, prepare appropriate CEPT positions and, if needs arise, proposals concerning protection of maritime and aeronautical HF distress and safety services. Issue 2There is a need to continue the protection of the maritime HF distress and safety frequencies from interference caused by commercial calling.In response to Resolution 346 (WRC97) on the protection of HF GMDSS communication frequencies, CEPT proposed to WRC2000 that all 5 HF frequencies, and especially the frequencies 12 290 and 16 420 kHz, should be exclusive for GMDSS.After long discussions, WRC2000 decided to make the two frequencies 12 290 and 16 420 kHz exclusive for distress and safety as from 31.12.2003 at the latest. WRC2000 however also adopted Resolution 350 (WRC2000) requesting monitoring studies and included this resolution in the agenda for WRC2003.

The possibility exists that some administrations will propose reconsideration of the decision taken by WRC2000 in this regard. CEPT should consider very carefully any proposals for

57


abrogating the decision or the postponement of the date for that decision coming into force. These considerations should also take due account of the results of ITU studies undertaken as a consequence of the deliberations surrounding that decision.

CEPT should carefully monitor the progress and outcome of the monitoring studies undertaken by ITU-R.

CEPT should propose to mantain the decisions taken at WRC 2000 concerning 12290 and 16420KHz and the allocation in art. S52 and appendix S17 of frequencies 12359 and 16359KHz for general calling on a simplex basis.CEPT should furthermore propose adoption of a resolution permitting MRCC’s to use 12290 and 16420KHz also for limited general calling for safety related communications, subject to specified safeguards.

Issue 3There is a need to optimize the use of the maritime MF and HF bands, if necessary by adopting more spectrum efficient technologies.Use of some maritime mobile services such as Morse telegraphy are declining, and it is therefore appropriate to review parts of the channel arrangements for the maritime mobile services in order to make sufficient spectrum available for other emerging replacement maritime mobile service technologies such as, for example, data communications. In light of its declining use, the spectrum currently allocated for Morse telegraphy is an ideal candidate for the testing and introduction of such technologies. This additional allocation can be facilitated by the insertion of a footnote to the Table of Sub-divided Bands in Appendix S17 which details the frequencies and channelling arrangements for the HF maritime mobile service. It is also considered no longer necessary to maintain the procedures of calling, traffic and frequency assignment for HF Morse telegraphy in the Radio Regulations but deletion of the existing provisions would require many changes of an editorial nature that are considered unnecessary at this time.

WRC97 modified provisions on the use of maritime frequencies, thus making it possible to use MF and HF F1B channels, HF A1A channels and HF J3E channels also for data transmissions (S52.3, S52.54.1 and S52.217).

There is a need to undertake studies to develop new digital technology, which offer significant improvements in spectrum efficiency. The potential market for such technology in the maritime community may be insufficient to independently develop new systems, even on a global basis.

Digital technology has already been developed in the MF and HF bands for use by the broadcasting and radio-amateur services. Digital Radio Mondiale is one example of a European led development which has been adopted by the ITU through Recommendation ITU-R BS.1514. PACTOR II is an example of a system already developed and for example in use by radio-amateurs and United Nations.

Given the similar technical characteristics of some of the maritime requirements to those characteristics employed by these technologies, it is important that the possibilities of adapting these technologies to meet the maritime requirements are investigated fully.

A draft resolution is being considered within SE31. This advocates that the ITU-R should undertake research into the future utilisation of maritime MF and HF communications and

58


the suitability of different technologies to meet the requirements of the maritime mobile service.

Use of Morse telegraphy in the maritime mobile service is declining, the spectrum currently allocated for Morse Telegraphy is an ideal candidate for the testing and introduction of such technologies. This new designation can be facilitated by the insertion of a footnote to the Table of Sub-divided bands in Appendix S17 which details the frequencies and channelling arrangements for the HF maritime mobile service.

(to be further developed)

Other matters

None of the CEPT countries has made initiatives concerning re-allocation of the HF frequency bands. The International Frequency List contains a considerable amount of assignments on all aeronautical mobile (R) and maritime-mobile HF bands. Although there is considerable use of the HF bands of both services, the current situation does not justify re-allocation of spectrum between the maritime mobile and the aeronautical mobile (R) services.The frequency allotment Plan for the aeronautical mobile (R) service is contained in Appendix S27 of the Radio Regulations and the allotment plan for the maritime mobile service in Appendix S25. Due to congestion in the bands allocated to AM(R)S, the ICAO, in collaboration with the Radiocommunication Bureau, is researching the possibility for further allotments in accordance with the provisions of Appendix S27.

Preliminary CEPT position:CEPT should continue to oppose proposals regarding re-allocation of MF/HF frequencies between the aeronautical mobile (R) and the maritime mobile services.

Agenda Item 1.11 – Allocation to AMSS at 14 GHz

WRC-2003 agenda item 1.11: To consider possible extension of the allocation to the Mobile Satellite Service (earth to space) on a secondary basis in the band 14-14.5 GHz to permit operation of the Aeronautical Mobile Satellite Service as stipulated in resolution 216 (Rev. WRC 2000)

Introduction

Agenda item 1.11 requests the conference to consider the possible extension of the allocation to the mobile-satellite service (MSS) (Earth-to-Space) on a secondary basis in the band 14-14.5 GHz to permit operation of the aeronautical mobile-satellite service (AMSS).

All or parts of the band 14-14.5 GHz are allocated on a primary basis to the fixed-satellite service (Earth-to-space), radionavigation, and fixed and mobile services (except aeronautical mobile service). Secondary services allocated in all or parts of the band include: mobile-satellite service (Earth-space) (except AMSS), space research, radio astronomy, and radionavigation satellite. MSS systems have been in operation for many years offering land and maritime mobile satellite services with a proven ability to operate in co-existence with all other services having primary or secondary allocation in the same band. The restriction to land and maritime operations in the Radio Regulations is no longer justified. The AMSS in the 14-14.5 GHz band is being proposed to meet a growing demand for two-way broadband communications by passengers and operators of commercial aircraft.

Resolution 216 (Rev. WRC-2000) called for inter alia studies to assess the feasibility of sharing the band 14 – 14.5 GHz between primary services in the band and the AMSS, with the latter service on a secondary basis. Studies were performed with all services including those on a secondary basis (where operating parameters were available). The studies determined that these services can share the frequency bands providing that the AMSS operates within a defined operating characteristics. These characteristics are included in an ITU-R [preliminary draft new] Recommendation.

Agenda Item 1.14 Maritime Mobile and Aeronautical Mobile (R) services

in MF and HF bands

WRC-03 AGENDA ITEM 1.14 : to consider measures to address harmful interference in the bands allocated to the maritime mobile and aeronautical mobile (R) services, taking into account Resolutions 207 (Rev. WRC-2000) and 350 (WRC-2000), and to review the frequency and channel arrangements in the maritime MF and HF bands concerning the use of new digital technology, also taking into account Resolution 347 (WRC-97).

Introduction

There is an urgent need to make provision for the use of digital technology within the existing maritime MF and HF planned bands. This would enable existing and future commercial operators to make more economical use of the available spectrum and would facilitate the use of new technologies and equipment being introduced into the maritime environment.

It is likely that some of the sub-bands, previously heavily used, are not in use any more or used insignificantly. As an example, bands designated for Morse code, could be made available for other maritime purposes. Narrow-band direct printing telegraphy may be another declining type of frequency usage although it will still be needed as part of the GMDSS.

Re-allocation of the ineffectively used parts of the MF and HF bands should be considered for the benefit of these new services.

Issue

WRC-2003 agenda item 1.15: to review the results of studies concerning the radionavigation-satellite service in accordance with Resolutions 604 (WRC-2000), 605 (WRC-2000) and 606 (WRC-2000).


Band 1 164 – 1 215 MHz (Res 605)The studies on refinement of the DME protection ratio against RNSS signal, the DME antenna discrimination towards RNSS satellites, the apportionment of sources of interference have been completed. Continuing studies on the development of a methodology to derive single-entry limits from aggregate limits shall be supported. In this band, limits in terms of equivalent power flux density (epfd) caused by all the space stations of all radionavigation satellite systems at the Earth’s surface for all angles of arrival the value of –121.5.6 dB(W/m2)

in any 1 MHz shall be supported.In addition to the aggregate limit, a limit per RNSS system would also be required, but further study of the definition of such a limit is required in order to ensure the equitable sharing of the power/frequency resource between the different RNSS systems.

Band 1 215 – 1 300 MHz (Res 606)The studies on the development of pfd limits within the band 1215-1300 MHz shall be supported, paying due account to the existing sharing between RNSS and radars in this frequency band.For the protection of the radiolocation and radionavigation systems in the whole of the band 1 215-1 300 MHz a pfd limit of [–133 dB(W/m2)] in any 1 MHz per each single RNSS satellite shall be supported.Option C of the CPM text proposing limits in the band 1260-1300 MHz and not in the band 1215-1260 MHz should be strongly rejected as not providing the same operational constraints for Galileo and other RNSS systems

Note : In order to protect their radionavigation/radiolocation systems, one Administration expressed the view that more stringent pfd limits for RNSS systems are necessary in the band 1260-1300 MHz than in the band 1215-1260 MHz. This Administration strongly opposes the position to provide the operational constraints based on RNSS systems characteristics operating in the frequency band 1215-1260 MHz to the RNSS in the whole band 1215-1300 MHz because it will not provide adequate protection to radionavigation/radiolocation systems in the band 1260-1300 MHz. This Administration therefore believes that option C of the CPM text should be considered along with other options provided at the draft CPM report. This administration also opposes the inclusion into RR S5.329 of provisions that the RNSS in the band 1215-1300 MHz shall be subject to the condition that no protection is claimed from the Radiolocation service because this is not within the scope of the Resolution 606


(WRC-2000) and would change the reciprocal status of the various services using this band (i.e. RNSS against RLS).

Note : Eurocontrol has undertaken a study based on measurements on ATC radars and the CEPT position may need to be reconsidered after the availability of the results.

Band 5 010 – 5 030 MHz (Res 604)The ITU-R studies on the application of epfd concept to protect radio astronomy, the pfd level of [–171dBW dB(W/m2) in a 10 MHz band] for any GSO RNSS satellites and the epfd level of –246 dB(W/m2) in a 10 MHz band for any NGSO RNSS systems shall be supported.In this band, the protection of radio-astronomy in the band 4990-5000 is ensured through a new footnote.

Background

WRC- 2000 allocated the bands 1 164 – 1 215 MHz, 1 260 – 1 300 MHz and 5 010 – 5 030 MHz to the RNSS (space-to-Earth) (space-to-space) in accordance with Resolutions 604, 605 and 606 (WRC-2000). These new allocations are essential for the development and enhancement of new and existing RNSS systems like GALILEO, GPS and GLONASS.The European Union initiated the development of a second-generation European radionavigation-satellite system, Galileo. It is being designed as an independent, global, civil-controlled system which will be used, together with other RNSS systems, as a key element of the second-generation global navigation-satellite system, GNSS-2. Galileo will provide open access and controlled access services, including reliable signals for safety-of-life applications, such as civil aviation and maritime transport.The US, UK, China and Russian Federation have also announced plans to use parts of the allocation for GSO/NGSO systems.

Band 1 164 – 1 215 MHz (Res 605)

In the band 1164 – 1215 MHz a provisional pfd limit has been introduced for the protection of the ARNS systems operating in this band. The need for and the value of this provisional limit need to be verified at WRC-03 in accordance with Res 605 (WRC-2000). The protection of the DME and TACAN systems operating in this band is essential for the safety of air traffic.This spectrum is part of the 960-1 215 MHz band which is allocated to the aeronautical radionavigation service. There are no airborne ARNS emissions in the 1 164 - 1 215 MHz portion of this band which is used for ground-based DME and TACAN. In Europe, DME and TACAN installations will continue to be used in conjunction with RNSS systems. This may result in an increase in the requirements for DME/TACAN in Europe and this use is foreseen to extend to 2015 and beyond. The continued operation of current systems is therefore a prime consideration.

The pfd limit defined during WRC-2000 has been based on several assumptions concerning the protection ratio of DME from RNSS signal, the airborne DME antenna discrimination towards RNSS satellites, the apportionment of interference sources. All these assumptions needed to be confirmed and measurements as well as simulations were required.SE 28 is in view that epfd limit is more appropriate than pfd limit to protect ARNS as the epfd reflects more accurately the interference to ARNS systems and takes into account GSO and NGSO RNSS systems. SE 28 has determined a reference DME/TACAN antenna to be used for epfd calculation and has carried out measurements to assess the difference of impact between CW and RNSS


interfering type of signal. A polarisation mismatch of -2dB is used for the epfd limit determination. Regarding the difference of impact between CW and RNSS type signals on DME interference threshold, two studies have been performed: One provides from 1 to 2 dB positive margin between the CW interference threshold and the RNSS one, the other one, 1 to 2 dB negative margin. As a compromise, the value of 0 dB is proposed. Finally, the aviation proposal on the apportionment of interference source ( 6 dB ) has been accepted. This gives an epfd limit for all RNSS systems of –121.5 dB(W/m2) in any 1 MHz.

The epfd limit is valid for the aggregate interference from all RNSS systems. The derivation of single-entry limits for each RNSS system is also to be investigated for WRC-2003 to ensure optimum sharing of frequency/power resource between RNSS systems.

Band 1 215 – 1 300 MHz (Res 606)

At WRC-2000 CEPT proposed to introduce in the band 1 215 – 1 300 MHz a pfd- limit, with a proposed value of –133 dBW/m²/MHz per satellite. Due to the strong opposition of the US and Russia to introduce any pfd limit in the band 1215 – 1260 MHz already used by GPS and GLONASS, Resolution 606 (WRC 2000) was approved calling for the necessary studies to assess the need for and the value of the pfd limit in the band 1 215 – 1 300 MHz to protect the radionavigation and radiolocation service and resolves 1 clearly states that no additional constraints shall be placed on radionavigation-satellite service (space-to- Earth) systems operating in the band 1 215-1 260 MHz..Preliminary studies, based on a worst case analysis, showed that the existing pfd levels of GPS and GLONASS systems in L2 exceed the radars protection criteria, although no interference case has been recorded. This suggested that more realistic analysis were necessary to determine the appropriate pfd. Therefore, a statistical study performed, using more realistic models of radars and satellites constellations confirmed that the protection criterion required in ITU recommendations was most of the time exceeded. All the sharing studies carried out, show that the current required protection criterion in relevant ITU-R recommendations may not be adequate. Due to the difficulty to define the level of interference that could be acceptable by radionavigation and radiolocation service systems and since no case of interference from currently operational RNSS systems into radar systems has been recorded, it seems reasonable to ensure the protection of radar systems by means of a pfd limit which would be the pfd value of currently operating systems.. Therefore, the pfd value of [–133] dBW/m2/MHz per RNSS satellite, which has been assessed based on the expected pfd level of current GLONASS system, has been proposed as pfd limit in the Radio Regulations in the 1215-1300 MHz band to protect radionavigation and radiolocation services and is under study. In any case, it would not be acceptable to have pfd limits applying only to the higher part of the band, where Galileo will operate, and not in the lower part of the band.Remarks : In addition to the RNSS, these bands are allocated by footnote S5.331 to the radionavigation service in several countries on a primary basis. According to S5.282, the amateur-satellite service (Earth-to-space) may operate in the band 1 260-1 270 MHz subject to not causing harmful interference to other services operating in accordance with the table (see S5.43).

WP8B send already a liaison statement to WP8D stating that the same sharing conditions should be applied in the whole 1215 – 1300 MHz range

Band 5 010 – 5 030 MHz (Res 604)


To protect the radio astronomy service below 5 000 MHz a provisional pfd limit, that applies to out-of-band emissions from RNSS systems operating in the band 5 010-5 030 MHz falling into the radio astronomy band 4 990-5 000 MHz was approved by WRC-2000 in accordance with Resolution 604 (WRC-2000). Due to the ongoing studies the pfd limit for the RNSS is subject to revision at WRC-03.The general problem of protection of radio astronomy and passive services is under study in ITU-R, inter alia, in response to Recommendation 66. In this respect, TG1/7 has been recently created to answer to WRC-2003 agenda item 1.8.2, ie. the protection of passive services from space stations. In support of such activity, WP4A and WP7D have undertaken studies on the application of epfd concept to the protection of radio astronomy and WP7D has indicated that the provisional pfd limit would be likely to be modified accordingly. The results of this work should be applied to the RNSS emissions into the 4 990 – 5 000 MHz band. Agenda item 1.8.2 is handled by SE21.The ITU-R studies on the application of epfd concept to protect radio astronomy, the pfd level of –171dBW dB(W/m2) in a 10 MHz band for any GSO RNSS satellites and the epfd level of –246 dB(W/m2) in a 10 MHz band for any NGSO RNSS systems shall be supported to protect radioastronomy below 5000 MHz. However those limits could be revised with the outputs of 7D, TG1/7, and SE21.

SUB-PART […1]

Resolution 605 - RNSS (space-to-Earth) 1 164 – 1 215 MHz

Introduction

1 In accordance with the Radio Regulations, the band 960-1 215 MHz is allocated on a primary basis to the aeronautical radionavigation service in all ITU regions.2 In accordance to footnote S5.328 the use of the band 960-1 215 MHz by the aeronautical radionavigation service is reserved on a worldwide basis for the operation and development of airborne electronic aids to air navigation and any directly associated ground-based facilities. The 1 164-1 215 MHz portion of that band is used by ground DME and TACAN transponders.3 Results of ITU-R studies show that additional radionavigation-satellite service signals in the band 1 151-1 215 MHz can be designed that do not cause harmful interference to existing aeronautical radionavigation service systems (SSR, ACAS, DME, TACAN). In order to ensure protection of the aeronautical radionavigation service systems a provisional pfd limit for the radionavigation-satellite service has been approved by WRC-2000 in accordance with Resolution 605 (WRC-2000).

4 In response to Resolution 605 (WRC-2000) the need for and the value of a pfd-limit has been assessed by ITU-R. ITU-R is expected to conclude that an epfd value of –121.5 dBW/m²/MHz would be adequate to ensure the protection of aeronautical radionavigation systems.

5 The above mentioned countries therefore propose new provisions in the radio regulation to ensure that the equivalent power flux-density produced by all the space stations of all radionavigation-satellite systems at the Earth's surface does not exceed –121.5 dB(W/m2) in any 1 MHz for all angles of arrival

Resolution 606 - RNSS (space-to-Earth) 1 215 – 1 300 MHz

Note: this ECP , in particular the removal in S5.329 of the provision that “RNSS shall not cause harmful interference…” is based on the assumption that an agreement can be reached on the pfd level.

Introduction

1 In accordance with the Radio Regulations, the band 1 215-1 300 MHz is allocated on a primary basis to the Earth exploration-satellite service (active), the radiolocation service and the space research service (active) in all ITU regions. In addition, the band is primary allocated by footnote S5.331 to the radionavigation service in several countries.

2 For the protection of the radiolocation and radionavigation systems in the whole of the band 1 215-1 300 MHz a pfd limit of [ –133] dB(W/m2) in any 1 MHz per each single satellite for the RNSS is proposed. It should be noted that further studies on the protection of the radiolocation/radionavigation for the band 1215 – 1300 MHz might be required.

Note: Eurocontrol has undertaken a study base on measurements on ATC radars and the CEPT position may need to be reconsidered after the availability of the results. Note: This draft ECP has been modified based on proposals by several administrations. One administration has expressed concerns about these proposals concerning articles S5 and S21 modifications that allow the same pfd limit for RNSS in the whole 1215-1300 MHz band that may additionally constrain current RNSS systems operating in the band 1215-1260 MHz or that could not provide adequate protection to radionavigation/radiolocation systems in frequency band 1260-1300 MHz. This administration also opposes the inclusion into No. S5.329 of provisions that the Radionavigation Satellite Service in the band 1215-1300 MHz shall be subject to the condition that no protection is claimed from the Radiolocation service because this is not within the scope of the Resolution 606 (WRC-2000) and would change the reciprocal status of the various services using this band (ie RNSS against RLS).

Resolution 604 (WRC-2000) - RNSS (space-to-Earth) 5 010 – 5 030 MHz

Introduction

1 In accordance with the Radio Regulations the band 5 000-5 150 MHz is allocated on a primary basis to the aeronautical-radionavigation service in all ITU regions.2 Results of ITU-R studies show that radionavigation-satellite service (space-to-Earth) signals in the band 5 010-5 030 MHz can accommodate the protection requirements of the RAS contained in Recommendation ITU-R RA.769-1 within the RAS allocated bands. In order not to cause harmful interference to the radio astronomy service in the band 4 990-5 000 MHz, the power flux-density radiated in the 4 990-5 000 MHz band by all the space stations within any GSO RNSS (space-to-Earth) system operating in the 5 010-5 030 MHz band shall not exceed the level of –171 dB(W/m2) in a 10 MHz bandwidth into any radio astronomy observatory site for more than 2% of the time and the equivalent power flux-density radiated in the 4 990-5 000 MHz band by all the space stations within any NGSO RNSS (space-to-Earth) system operating in the 5 010-5 030 MHz band shall not exceed the level of –246 dB(W/m2) in a 10 MHz bandwidth into any radio astronomy observatory site with 75 dBi reference antenna gain for more than 2% of the time for more than 5% of the visible sky 3 Application of the epfd concept to the protection of radio astronomy from NGSO systems has been studies in ITU-R (WP 4A, WP8D, WP7D and TG1/7). A set of recommendations defining protection criteria and methodology of calculation has been approved.

Agenda Item 1.17 – Radiolocation at 2900-3100 MHz

WRC-2003 agenda item 1.17: To consider upgrading the allocation to the radiolocation service in the frequency range 2 900-3 100 MHz to primary

Introduction

The frequency band 2 900-3 100 MHz is allocated to the radionavigation service on a primary basis and to the radiolocation service on a secondary basis.

Applications in the radionavigation service in the frequency band 2 900-3 100 MHz are mainly maritime radars either on ships or on shore. Some aeronautical radar systems are operated only in a limited number of countries, in the lower part of this frequency band. Various military radar applications account for use of the radiolocation service in this band. Typical radar systems are described in the ITU-R Recommendation ITU-R M 1460.There has been satisfactory co-existence for many decades, of various radar systems in the Band 2 900-3 100 MHz, which include systems operating under the radionavigation and the radiolocation service. Taking this into account, together with the results of the studies undertaken within ITU-R, the following changes are proposed to the Radio Regulations, which will serve to satisfy the agenda item.

Reasons: Upgrading the allocation for the radiolocation service helps to fulfil the requirements of radiolocation operations without establishing constraints to applications operating in the radionavigation service. Footnote S5.426A serves to ensure this, in that future stations under development operating in the radiolocation service,

will not compromise existing stations operating in the radionavigation service.

Agenda Item 1.22 : To consider progress of ITU-R studies concerning future development of IMT-2000 and systems beyond IMT-2000, in accordance with Resolution 228 (WRC-2000)

Issue

In Resolution 228 ITU-R was invited to continue studies on overall objectives, applications and technical and operational implementation for the future development of IMT-2000 and Systems Beyond. It was also invited to study spectrum requirements and potential frequency ranges suitable for the future development of IMT-2000 and systems beyond IMT-2000, and in what time-frame such spectrum would be needed.

The requirements for the future development of IMT-2000 and Systems Beyond are to be reviewed by WRC-2006, taking into consideration the results of ITU-R studies presented to WRC-2003.

Preliminary CEPT Position

1. WRC-2003 should ensure that there is an appropriate agenda item for WRC-06 to enable spectrum to be identified for IMT-2000 and Systems Beyond. Further studies are required to see if the two new elements, mobile and nomadic/local area wireless access, illustrated in the diagram shown below in Figure [1] should and could be accommodated in different frequency bands or a single band. It is assumed at this stage that spectrum for the ‘mobile access’ should be as close to the existing IMT-2000 frequency bands as possible and the desired spectrum range for ‘nomadic access’ is for further study. It should also be noted that ‘mobile’ and ‘nomadic’ access do not necessarily imply two distinct radio access technologies; the feasibility of achieving this with either an adaptive interface or multiple interfaces with maximum commonality, subject to the ongoing market considerations and service developments, is for further research.

2. The availability of any additional spectrum for the potential new radio interface(s), as discussed above, depends on many factors. The CEPT view is that at some point in the future there will be a requirement for further additional spectrum but until IMT-2000 systems are rolled out and market experience is gained then a cautious approach should be taken. The spectrum identified at WRC-2000 should also be as fully utilised as possible before any further spectrum is made available. A date of 2010 is mentioned in ITU-R WP8F, and this is supported as a general target date to provide a focus for the research and development activities, but more detailed discussions on potential spectrum availability should be taken between WRC-03 and WRC-06 once mobile multimedia data services have been widely deployed and sufficient market experience has been gained. The knowledge from the characteristics and trends be used in evaluating the potential market requirements for the ongoing development of IMT-2000 and Systems Beyond IMT-2000.

3. The high level approach taken within ITU-R Working Party 8F to distinguish three main trends of technology development, as discussed below, is supported: The existing IMT-2000 radio interfaces and networks will continue to be enhanced

throughout their operational life times, perhaps reaching service bit rates of 20-30Mbit/s.


There will be an increasing relationship between IMT-2000 (as it is enhanced throughout its life) and other radio systems (possibly including WLAN andDigital Broadcasting.).

It is likely that new elements will be required to deliver the complete Vision, especially in the areas of terrestrial ‘mobile’ access and terrestrial ‘nomadic’ access. These will also form part of the relationship with other radio systems.

4. Any decisions at WRC-03 in relation to agenda item 1.21 should not conflict the CEPT position given in number 1 above.

Background

The WARC-92 identified, in footnote S5.388, the frequency bands 1885 – 2025 MHz and 2110 – 2200 MHz for IMT-2000, including 1980 – 2010 MHz (uplink) and 2170 – 2200 MHz (downlink) for the satellite component. This is reflected in Resolution 212, which was drafted at WARC-92 and amended at WRC-95 and WRC-97. Further developments at WRC-95 led to the allocation in Region 2 of the frequency bands 2010 – 2025 MHz (uplink) and 2160 – 2170 MHz (downlink), from within the IMT-2000 range, for MSS.

WRC-2000 considered again issues related to IMT-2000, resulting in the identification of additional spectrum for IMT-2000.

The envisaged capabilities of IMT-2000 and Systems Beyond as foreseen in the year 2010 are illustrated in Figure [1]. The first and second trends of technology development listed in CEPT position number 3 are considered to fall largely within the “future development of IMT-2000”. The third technology trend listed above is considered to fall within “Systems Beyond IMT-2000”.

A further item that is being explored, both within WP8F and JTG1689, is the relationship between the ongoing development of IMT-2000 with other radio access systems. JTG-1689 has concluded that IMT-2000 and Systems Beyond can be considered to fall within


the scope of terrestrial wireless interactive multimedia applications however it is unclear at present what the impact of the work of JTG-1689 (WRC-03 agenda item 1.21) is on this agenda item.

Actions to be taken in preparation for WRC-2003

1. To better define the evolution of IMT-2000 and Systems Beyond, including capabilities, services and possible frequency ranges if needed.

2. Explore the relationship of the ongoing development of IMT-2000 with other radio

systems and the regulatory consequences. Clarification of the potential relationship with the studies under agenda items 1.21, 1.3 and 1.5.

3. Contribute to the ITU-R WP 8F work on the development of a preliminary draft new recommendation Vision framework and overall objectives of the future development of IMT-2000 and of Systems Beyond IMT-2000 and on preparation for the CPM text, ensuring that the CEPT position is correctly represented.

4. CEPT should further develop its objectives for WRC-06 and formulate a suitable Agenda Item for WRC-06 on future development of IMT-2000 and Systems Beyond to be included in the ECP for agenda item 7.2.

APT Members recognized in principle to continue the studies of the overall objectives, service applications, technical, operational implementation and associated matters as necessary for future development of IMT-2000 and Beyond systems.

APT Members recognized that the spectrum requirements and potential frequency ranges suitable for the future development of IMT-2000 and Beyond systems, should be considered and in the time-frame that such spectrum would be needed be identified.

APT Members generally support that Sector members of ITU, particularly network operators and manufactures in APT region, should participate in ITU-R activities, with prior consultations and communication, to reflect APT Members’ requirements on the future development of IMT-2000 and Beyond systems.

Draft proposal

- Members are recommended to participate actively with prior consultations and communication in the work of ITU-R WP8F.

- Establish APT view when the results of relevant ITU-R studies are available.

Agenda item 1.28 : to permit the use of the band 108-117.975 MHz for the transmission of radionavigation satellite differential correction signals by ICAO standard ground-based systems;

Issue

Civil Aviation expressed a need for transmitting radionavigation satellite differential correction signals (e.g. Differential GPS) in the VHF aeronautical radionavigation band.


The proposal in this agenda item will significantly benefit aviation within Europe and will also ensure that existing services in the band are protected. Therefore CEPT support the introduction of Ground Based Augmentation System (GBAS) which is transmitting satellite differential correction signals.

CEPT also support the introduction of systems introducing surveillance functions in air traffic management (VHF Digital Link Mode 4, VDL Mode4) subject to demonstration that compatibility can be achieved without placing any additional constraints on other services. CEPT will take a final decision when the result of the compatibility study is available.

A new aviation requirement has emerged for the transmission of augmentation data for GNSS, to be used by aircraft receivers to satisfy the stringent accuracy and integrity requirements for GNSS applications. ICAO plans to operate the new ground-based augmentation systems (GBAS) in the present VOR/ILS band at 108-117.975 MHz

The band 108-117.975 MHz is currently allocated to the aeronautical radionavigation service. Footnote S5.197 gives an additional allocation for secondary mobile service subject to agreement under S9.21 and other restrictions in several countries ( Japan, , Pakistan, and Syria ).

It has been argued that GBAS does not fall within the definition for a radionavigation service (i.e. using the property of the propagation characteristics of radio waves) and that an amendment to the allocation of this band is required to allow for GBAS operations.

Compatibility and frequency planning criteria for the VOR/ILS and the new service are being developed by ICAO. Development of GBAS is not supposed to cause any additional constraints to FM broadcast service.Work has been initiated in WP8B but no contribution has been received so far on this subject.

For the new systems that are intended to operate in this band, ICAO has adopted relevant Standards and Recommended Practices and incorporated these in Annex 10 to the Convention

DRAFT ECP’s Annex V to the CPG03-3 Report – Document CPG(2002)27r1 – Page 92 of 106on International Civil Aviation. One such system is the Ground Based Augmentation System (GBAS) of the ICAO Global Navigation Satellite System (GNSS), which is transmitting satellite differential correction signals. This component in an essential element for the safe use of RNSS by aircraft. The transmitters are ground based. Protection of this system needs to be assured throughout the designated operational coverage of the system, which includes the approach and landing phase of flight. ICAO also wants this band to used for flight surveillance system. The recommended ICAO system (VHF Digital Link Mode 4, VDL Mode4) transmits from the aircraft its position and other relevant data either automatically or in response to ground station requests (Automatic Dependent Surveillance, ADS). This information is to be received by other aircraft and/or by ground stations and is used to establish safe separation between aircraft..

Working Party 8B of the ITU-R Study Group 8 has developed draft CPM text on possible methods to meet the objectives of agenda item 1.28.

The methods that currently are considered in ITU-R are

Method 1. The adoption of a footnote that would enable the use of the band 108 – 117.975 MHz on a worldwide basis for the transmission of radionavigation differential correction signals by international aeronautical standard systems. Since this would enable only the use of the GBAS system, as standardized by ICAO, and would not include provisions enabling the introduction of VDL Mode 4 in this band, the agenda for WRC [2006] should include an agenda item which addresses expanded aeronautical surveillance application in this frequency band.

Method 2. The adoption of a footnote that will permit the use of the band 108 – 117.975 MHz on a worldwide basis for the use and development of ICAO standard systems that support navigation and surveillance functions through a communication data link, on the condition that priority and protection be given to the aeronautical radionavigation service.

Agenda Item 1.31 – New allocations to the Mobile-satellite Service

WRC-2003 agenda item 1.31: To consider the additional allocations to the mobile-satellite service in the 1-3 GHz band, in accordance with Resolutions 226 (WRC-2000) and 227 (WRC-2000)

Introduction

The 1.5/1.6 GHz band MSS allocations are heavily used today, leaving little scope for further expansion in these bands. The experience at the Region 1&3 1.5/1.6 GHz band Operators’ Review Meeting has confirmed that the 1.5/1.6 GHz band MSS spectrum is congested.

The CEPT proposed allocations to the MSS in the bands 1 518-1 525 MHz (space-to-Earth) and 1683-1690 MHz (Earth-to-space) at WRC-2000. However, these allocations were not made mainly due to a requirement for additional sharing studies in the band 1518-1525 MHz.

Sharing between the MSS and FS has been previously examined in great detail within the ITU resulting in a number of ITU-R Recommendations. Additionally the Radio Regulations specifies (in Table 5-2 of Appendix 5) the power flux-density (pfd) values produced at the Earth's surface applicable as coordination thresholds for the protection of the FS.

Studies conducted within ITU-R and CEPT have confirmed that these pfd values provide adequate protection to FS systems from MSS space stations. [The studies are ongoing to confirm the applicability of the pfd values to protect some types of point-to-multipoint systems, which are expected to continue operation for the foreseeable future in some Region 3 countries.]

In the territory of Japan, the following pfd coordination threshold applies: -150 dB(W/m2) in 4 kHz at all angles of arrival as specified in Appendix 5. Recent ITU-R studies have recognized that this value continues to be applicable.


[Further ITU-R studies have shown that pfd thresholds [of xxx dB(W/m2/4kHz)] ensure the protection of aeronautical telemetry systems operating in the band 1 518-1 525 MHz. Such a protection value would allow sharing between some types of MSS systems and the mobile service for aeronautical telemetry.]

Sharing studies indicate that co-channel sharing between MetAids and MSS is not feasible due to unacceptable levels of interference to both systems. Studies also indicate that time-sharing between MetAids and MSS is also not feasible due to the operational nature of both services.

The ITU-R has reviewed the studies regarding MetAids use of the band 1 683-1 690 MHz and concluded that few MetAids systems operated in the band 1 683-1 690 MHz can be concentrated in the range 1 675-1 683 MHz in most countries if sufficient time for transition is provided.

[ITU-R studies on sharing between the MSS (E-s) and the meteorological satellite service (s-E) are completed and recorded in Recommendation ITU-R SA.1158.]

With regard to sharing between MSS space stations and MetSat space stations, ITU-R studies have shown that sharing between MetSat space stations and MSS space stations is feasible except for some very close GSO constellations.

Resolution 227 (WRC-2000) notes that if the studies indicate an unsatisfactory conclusion for MSS operation in the band 1 683-1 690 MHz, then further sharing studies should be carried out in order to recommend alternative MSS (Earth-to-space) frequency bands in the 1-3 GHz range with WRC-2003 to consider making new allocations to the MSS (Earth-to-space), on a global basis, preferably in the vicinity of the existing MSS allocations around 1.6 GHz (but excluding the band 1 559-1 610 MHz).

Due to the foreseen sharing difficulties between the MSS and MetSat service in the band 1 683-1 690 MHz in Regions 2 and 3, the ITU-R has studied the band 1 670-1 675 MHz as an alternative band for an MSS allocation and concluded that from a sharing perspective this band is significantly better suited than the band 1683-1690 MHz.

Sharing between MetSat earth stations and MSS uplinks in the band 1 670-1 675 MHz is easier because there are fewer MetSat earth stations than in the 1 683 – 1 690 MHz band, particularly in Regions 2 and 3. An allocation to MSS in the band 1 670 – 1 675 MHz would therefore be preferable from the MetSat perspective, provided the MSS protect the relatively few MetSat earth stations through the use of exclusion zones and position determination.

There is limited usage of this band by MetAids in a few countries. However, a survey of the band indicates that MetAids frequency requirements can be satisfied with the spectrum available above 1675 MHz and hence the band is likely to become available in those few countries in the longer term.

Editorial Note 1: Appropriate modifications to the allocations and footnotes need to be considered, based on the outcome of sharing studies.

Editorial Note 2: The band 1670-1675 MHz is designated for use by TFTS systems in Europe. The future use of this band is being evaluated by the CEPT.

Editorial Note 3: The total requirement for the additional MSS uplink allocation in the 1.5/1.6 GHz band is 7 MHz.


Reasons:

- Sharing between meteorological aids, fixed service and the mobile-satellite service (uplink) is considered not practicable. It is expected that meteorological aids use can be concentrated in the frequency band 1 675 - 1 683 MHz in many countries.

- Recommendation ITU-R SA.1158 concludes that sharing between the meteorological-satellite service and the mobile-satellite service is feasible in the band 1 670 - 1 690 MHz if protection of the earth stations is guaranteed. However, sharing between MetSat earth stations and MSS uplinks in the band 1 670-1 675 MHz is significantly easier because this band contains only very few MetSat earth stations, whereas in the 1 683 – 1 690 MHz band the number of MetSat Earth stations is very large and increasing, particularly in Regions 2 and 3. An allocation to MSS in the band 1 670 – 1 675 MHz would therefore be preferable.

Editorial note: Appropriate modifications to the footnotes need to be considered, based on the outcome of sharing studies. This ECP also needs to be updated to reflect the conclusion of the continuing sharing studies between MSS and aeronautical telemetry.

Reasons:

1. Other services, including analogue and digital fixed services, in the band 1518-1525 MHz are protected from the MSS (including both GSO and NGSO services) by pfd thresholds as prescribed in Table 5-2 of Appendix 5.

2. High-density mobile applications for one country in Region 3 are protected from MSS transmissions as prescribed in Table 5-2 of Appendix 5 as referenced in footnote 5.348A.

3. These proposals contribute to alleviate the spectrum shortage for MSS and also to harmonise allocations between ITU Regions.
