INTRODUCTION Globally, the use of radio spectrum is regulated by the International Telecommunication Union (ITU). The ITU Radio Regulations form the international framework within which member nations allocate and manage spectrum at a more detailed level. In an age of technological convergence, spectrum management has become an increasingly complex and demanding task as ITU and its member nations are faced with the challenge of making spectrum available for new and existing services in the most optimal manner. In Singapore, the telecommunication industry is currently undergoing rapid changes in a newly liberalised environment. It is important that, at a time when operators are exploring business opportunities in Singapore, information on spectrum management are made available to facilitate potential investors in their decision-making. The objective of this paper is thus to inform the industry and interested parties on the availability of spectrum in the coming years, technological trends in the use of spectrum and IDA’s policy direction with regard to spectrum allocation and re-allocation for public communication networks. The paper should not be seen as an endorsement of any particular technology. SPECTRUM MANAGEMENT PHILOSOPHY AND SPECTRUM PLAN In the past, spectrum was administratively allocated as the number of players in the market was restricted and IDA individually approved the types of services to be offered within the licensed bands. However, in a liberalised environment, administrative allocation may not be the most objective, efficient and transparent means of ensuring that spectrum is put to its most effective use. This is especially so where there are competing demands over the same or similar spectrum bands and where competing services in common bands cannot effectively share the spectrum. IDA’s fundamental spectrum philosophy is thus to let market forces determine who should use spectrum and what spectrum should be used for, where possible. An auctioning process is deemed appropriate in consideration of the following three main factors. Firstly, a market-based approach seeks to allocate scarce resources to those who value it the most. Secondly, rapid advancements in technology make it difficult to establish a set of appropriate evaluation criteria for a “beauty contest” to pre-judge which operator is expected to be more efficient and effective in its network rollout and service offerings. Thirdly, an auction is a transparent process that will level the playing field for local and international players. As new and competing technologies emerge, bands within the radio frequency spectrum have been refarmed over the years by IDA in accordance with the ITU’s spectrum allocation plan. The attached Annex 1 shows Singapore’s Spectrum Allocation Chart. The table in Annex 2 provides an overview of the existing and planned services for the different radio frequency spectrum as well as the priority for spectrum review by IDA.

Mainly assigned for transmission of broadcasting content on a temporary basis

800 MHz & 900 MHz The 824-842.5 MHz/869-887.5 MHz bands were recovered in January 2000 and have not been reassigned. These bands have been reserved for digital cellular systems operating world-wide. In countries such as the US and S. Korea, there are CDMA (IS-95) systems operating in these bands. Such systems are capable of evolving into IMT-2000 air interfaces such as cdma2000 1X and 3X. On the other hand, European countries are using the 880-890 MHz/925-935 MHz bands for 2G Extended GSM (EGSM) services. Despite the announcement to the industry of the availability of the above bands, IDA has not received any interest to use the bands. A study on the policy of potential uses and the release would be conducted in 1Q2002 or earlier when it is

3

warranted by technological development or when IDA receives an interest to use the bands. The GSM900 spectrum band has been fully assigned to SingTel Mobile and M1. With the growing subscriber base of the two GSM900 networks and the impending introduction of GPRS for data services, IDA has approved the implementation of dualband by SingTel Mobile and M1. 1400 MHz IDA has allocated the 1400 MHz band for PDC mobile systems. However, to date, IDA has not received any indication from licensees that they would be interested in acquiring this band for mobile services. This band is therefore currently under review to see if alternative services could be offered. 1700 MHz & 1800 MHz The spectrum within the GSM1800 band has not been fully utilised. SingTel Mobile, M1 and StarHub Mobile are currently the only occupants of the band offering GSM1800 and dualband services. IDA is aware that with the advent of GPRS data services, the usage of airtime per subscribers will increase. This implies that additional spectrum will be required to support the same pool of subscribers. IDA announced on 22 January 2001 its intention to assign remaining 2G spectrum, via an auction approach. Only the existing three mobile phone operators were eligible to participate in the auction, scheduled for September 2001. As the Initial Offer received by IDA was equal to the total number of 2G Spectrum lots offered (6 lots of 5MHz x 2 each lot), the 2G Spectrum Rights were awarded to the three mobile phone operators without an auction. This additional spectrum is to cater for expansion of their current operations and enhancement of the range and quality of services offered. 3G Spectrum Bands ITU has identified the following spectrum for the implementation of 3G services:

(i) 1920-1980 MHz/2110-2170 MHz (FDD) (ii) 1885-1920 MHz (TDD) (iii) 2010-2025 MHz (TDD) (iv) 1980-2010 MHz/2170-2200 MHz (MSS)

In April this year, IDA issued three 3G spectrum licenses. SingTel Mobile, M1 and StarHub were each allocated 2 x 15 MHz of paired spectrum from 1920-1980

4

MHz/2110-2170 MHz (FDD) and 5 MHz of unpaired spectrum from 1900-1920 MHz (TDD) to roll out its services. IDA will continue to allow unlicensed cordless systems such as PHS and DECT to operate in the 1885-1900 MHz frequency range. The 1885-1900 MHz spectrum band will only be made available for 3G services when the need arises. As for the 2010-2025 MHz spectrum band, IDA intends to allocate it for 3G TDD unlicensed operations. The World Radiocommunication Conference 2000 (WRC-2000) in May 2000 identified additional spectrum bands to meet the demand for 3G services in the long term. The additional bands are:

(i) 806-960 MHz (ii) 1710-1885 MHz (iii) 2500-2690 MHz

However, as bands (i) and (ii) are currently used for 2G mobile services, only band (iii) would be made available for 3G services when demand picks up in future. It is likely that this additional 3G spectrum would be needed only after 2006. (ii) Public Radio Paging Services

Frequency Range Existing/Planned Services

Status

150-168 MHz 1-way paging Partially assigned 279-280 MHz 1-way paging Partially assigned 279-280 MHz/917-921 MHz 2-way paging Partially assigned 279-280 MHz/921-923 MHz 2-way paging Partially assigned As there are minimal spectrum constraints for both 1-way and 2-way paging services within these bands, it is more straightforward for interested parties to obtain the spectrum to provide paging services in Singapore. Because of increasing competition in the cellular market, growth in the paging industry has slowed down noticeably. IDA is therefore looking into deploying the unutilised portion of the spectrum for other innovative applications. For example, IDA has received proposals from the industry to use the paging frequencies in conjunction with mobile data and data casting services. IDA welcomes such proposals and interested parties may contact IDA to further discuss their proposals. (iii) Mobile Data Services

Frequency Range Existing System Status 415-417 MHz/425-427 MHz Mobitex Partially assigned 816-818 MHz/861-863 MHz DataTac Partially assigned

5

Mobile data networks are primarily used for asset tracking purposes. Transport and logistic companies such as those operating taxis or despatch services commonly deploy such networks. Like the paging industry, many mobile data services are gradually being replaced by cellular services. IDA will remain open to suggestions from the industry in utilising this band for other innovative uses. (iv) Trunked Radio Services

Frequency Range Existing/Planned Systems

Status

380-400 MHz TETRA Partially assigned 407-412 MHz/417-422 MHz MPT1327 To be recovered 410-430 MHz PMR/Analogue Trunk Partially assigned 450-470 MHz PMR Mostly assigned 806-816 MHz/851-861 MHz IDEN trunked radio Mostly assigned Unlike paging and mobile data, some of the trunked radio features cannot be replaced by cellular services. For example, the ability to make one-to-many group calls using trunked radio is a feature which cellular networks have yet to offer. One-to-many group calls are crucial for operations that require information to be verbally communicated to all field staff in different locations simultaneously. The industry is seeing an increase in the demand for trunked radio services. Like the introduction of WAP for GSM networks, trunked networks are expected to be able to support data services in the near future. To cater to the anticipated increase in demand, IDA has identified the 410-430 MHz and 450-470 MHz spectrum bands as potential spectrum bands for digital trunk radio services. A potential alternative system in the 450-470 MHz spectrum band is the GSM400 system. ETSI will release a GSM400 specification as part of its ETSI/SMG GSM99 specification. There are however constraints to operate GSM400 because of its limitation in expansion due to the small amount of spectrum available. Tentatively, IDA intends to recover part of the 410-430 MHz spectrum for digital trunk radio services, as part of the band is currently also used for Mobile Data Services. IDA will consult the industry on the allocation of this band in due course.

Fixed Services (i) Point-to-Point Fixed Links

Frequency Range Channelling Plan Utilisation Sharing with Fixed Satellite Services

(FSS) 5925-6425 MHz Rec F. 383 High FSS (Uplink) 6430-7110 MHz Rec F. 384 High FSS (Uplink) 7125-7725 MHz Rec F. 385 High FSS (Downlink) 7725-8500 MHz Rec F. 386 High FSS (Uplink)) 10.5-10.7 GHz Rec F. 747 High - 10.7-11.7 GHz Rec F. 387 High FSS (Downlink) 12.2-12.7 GHz Rec F. 746 High FSS (Downlink) 12.75-13.25 GHz Rec F. 497 Medium FSS (Downlink) 14.4-15.35GHz Rec F. 636 Medium FSS (Uplink) 17.7-19.7 GHz Rec F. 595 Medium FSS (Downlink) 21.2-23.6 GHz Rec F. 637 Low - IDA has reserved the above spectrum bands for point-to-point fixed links which could serve as: • Back-up backbone links between major exchanges or to link Singapore to off-

shore islands or border areas of neighbouring countries; • Links for local access networks to be provided by Facilities-Based Operators

(FBOs); • Links for broadcasters to perform outdoor broadcasting; and • Links for use by government agencies. Point-to-point fixed links are assigned individually, as it is possible to reuse frequency for different purposes with sufficient physical separation. IDA requires operators to justify the requirement of a fixed link in their applications and the actual spectrum allocated will depend on spectrum availability at the time of approval. Each point-to-point fixed link is subject to renewal by IDA on an annual basis. The utilisation of spectrum below 12 GHz is high. These lower microwave bands are popularly used for traditional fixed links as they are suitable for longer distance applications albeit having smaller channel bandwidth. Frequencies within the 5925-6425 MHz and 6430-7110 MHz bands are also being used for Fixed Satellite Services (FSS). At present, the demand for spectrum above 12 GHz is relatively low. This is because higher microwave bands experience greater path loss and rain attenuation and are thus more suitable for short distance broadband applications. With broadband technology evolving at a rapid pace, there is a strong likelihood that demand for such high frequencies would increase significantly in the near future.

7

(ii) Fixed Wireless Broadband (FWB) IDA is aware of the interest by operators to use fixed wireless access technology as an attractive broadband solution. As such, IDA has reserved a portion of the 24.5-31.3 GHz spectrum band for fixed wireless broadband (FWB) services. As wireless access technology can serve as a quick alternative for new FBOs to break into the broadband market, IDA intends to release sufficient spectrum to encourage increased broadband service offerings and boost broadband penetration rates in Singapore. As announced on 17 August 2001, IDA has decided to auction sixteen lots of 2 x 28 MHz each in the 24.5 - 26.5 GHz band. The auction scheduled for September 2001 did not take place as there has been no interest from the industry. (iii) High Altitude Platform Stations (HAPS) HAPS are essentially transmitting stations operating in the stratosphere at an altitude of about 20 km. Balloons, manned aircraft or unmanned aircraft are commonly used to house such systems. The service coverage area of each HAPS ranges from 150 km to 1000 km in diameter. The HAPS system is an attractive alternative solution to satellite as the cost is much lower. The two Radio Conferences of ITU (WRC-97 and WRC2000) have designated the 47.2-47.5 GHz/47.9-48.2 GHz and 18–32 GHz for use by HAPS. HAPS is more applicable for countries with a large landmass. For Singapore, it may not be practical to implement such a system, as co-ordination with neighbouring countries would be required. Nevertheless, IDA will keep close tabs on the development in HAPS technology and the findings and recommendations of the various ITU studies. (iv) Other Fixed Services

Frequency Range Status 31.8-33.4 GHz Not assigned 37-40 GHz Not assigned 40.5-43.5 GHz Not assigned 51.4-52.6 GHz Not assigned 55.78-59 GHz Not assigned 64-66 GHz Not assigned The above bands have been made available by WRC-2000 for high-density applications in the fixed services (HDFS). The propagation condition and high degree of frequency reuse enable the use of frequency bands above 30GHz for high-density deployment of wireless point-to-point and point-to-multipoint systems. These bands are currently unoccupied and IDA will continue to monitor the developments in this area and the availability of equipment. In light of the high

8

rainfall in Singapore, IDA welcomes any interested parties to conduct trial on HDFS systems in Singapore to investigate the feasibility of deploying such systems. IDA will make available these bands once there is a demand for use of these bands. Satellite Services (i) Fixed Satellite Services (FSS)

Frequency Range Uplink/Downlink Existing/Planned Systems

3400-4200 MHz Downlink 5850-7075 MHz Uplink 7250-7750 MHz Downlink 7900-8400 MHz Uplink 12.20-12.75 GHz Downlink 13.75-14 GHz Uplink

Systems using these bands include Intelsat, ST-1, AsiaSat, Thaicom, etc.

18.8-19.3 GHz Downlink 28.6-29.1 GHz Uplink

Teledesic

Fixed-satellite services (FSS) primarily involve communications between fixed earth stations via satellite, i.e. uplinks and downlinks. However, certain inter-satellite links and feeder links may also be established. The frequencies to be used by each satellite network are co-ordinated by the respective operators at bilateral/multilateral meetings, in accordance with the recommendations of the ITU. The satellite operators are responsible in ensuring the availability of frequencies for their networks through such concerted activities. The fixed-satellite service basically involves three spectrum bands, viz. 4-6 GHz, 7-8 GHz and 11-14 GHz. Although numerous bands above 20 GHz are also allocated for fixed-satellite services, none is presently in use. Currently, companies in Singapore can select any fixed satellite network to set up communications to their remote overseas offices to provide point-to-point international leased circuit (ILC) connectivity using Very Small Aperture Terminal (VSAT) technology. This ILC can be used for telephone, data, fax, video-conferencing and other applications. Fixed satellite bands can also be shared by other services, in particular terrestrial fixed services. The sharing criteria (e.g. the power flux density) are recommended by ITU to ensure that the mutual interference level is acceptable. The WRC-95 has allocated spectrum in the 18.8-19.3 GHz/28.6-29.1 GHz bands for Broadband Satellite Communication Service on a shared basis with existing services. However, as the demand for such services is still unclear, IDA will monitor the situation to see if a portion of these bands could be used for other services in Singapore.

(IMT-2000) ICO

Identified by ITU for 3G expansion

Demand for mobile-satellite services (MSS) has grown tremendously over the last decade. Until the early 1990s, only Inmarsat and the Russian Volna satellite networks provided mobile satellite communication services, mainly to ships for maritime purposes. Inmarsat soon added aeronautical and land MSS to its portfolio of services. In the mid-1990s, the world witnessed the emergence of four more land MSS systems in Australia, U.S, Canada, and Mexico in addition to Inmarsat’s 3r d generation system. All these systems use geostationary (GSO) satellites that operate in the limited MSS allocations (33 MHz) in the L-band (1.5-1.6 GHz) and provide voice and low bit-rate data services to mobile earth stations. The latest MSS system, ICO, is the only satellite system intended for IMT-2000 satellite telephony. The ICO satellite system will operate in the 1980-2010 MHz/2170-2200 MHz bands, which have been earmarked as MSS band to support 3G services. During the WRC-2000, a portion of the additional 3G spectrum within the 2500-2690 MHz spectrum band was identified as a MSS component, specifically, 2500-2520 MHz/2670-2690 MHz. However, individual administrations have the flexibility of deciding whether the bands should be used for MSS or converted for terrestrial 3G services based on market demand. In Singapore, part of this band is currently used by SCV on a yearly renewal basis. IDA will closely monitor the development of 3G mobile wireless communications to determine how best to allocate these bands. Broadcasting Services The planning and channelling of the broadcasting spectrum is carried out in international level (ITU), regional level (Asia-Pacific Broadcasting Union, ABU) and bilateral level (i.e. border coordination). As Broadcasting services are intended for high power and wide coverage, the use of spectrum requires close coordination with bordering countries. As such, there are only a certain number of channels in each broadcasting allocation that can be used in Singapore.

10

The usage plans for broadcasting services had already been established. With the advent of digital broadcasting, IDA had also planned the spectrum allocations for both digital audio and digital video broadcasting. To provide broadcasting services, a license is required from Singapore Broadcasting Authority (SBA). The clearance on the broadcasting transmission station will fall under the purview of IDA. Service Band(MHz) Channel

1452 - 1492 1.536 MHz A total of 5 channels. No transmission at present.

DVB (Digital Video Broadcasting)

494 - 790 8 MHz A total of 6 channels. 2 channels assigned.

DBS (Direct Broadcasting Satellite)

11700 - 12200 27 MHz A total of 12 channels. No transmission at present

Feeder for DBS 17300 - 17700 27 MHz A total of 12 channels. No transmission at present

(i) Digital Broadcasting and convergent spectrum The digital broadcasting technologies have improved the efficiency of spectrum usage. As mentioned, each digital channel is able to accommodate a few analogue programmes. As such, more spectrum resources can be made available for other services. With digitisation, there is a trend for the convergence of information, communication and broadcasting services. This is demonstrated in the case of interactive TV. This has triggered many countries to study the various possibilities to introduce other services using the frequencies initially meant for broadcasting services exclusively. There are a total of 5 channels for DAB in the 174-230 MHz band. Each of these channels can accommodate a few audio broadcasting programmes. For instance, the RCS SmartRadio station is currently using 2 DAB channels to simulcast six of its

11

programmes. However, due to the high prices of DAB radio sets, there are only a small number of such radio sets being used in Singapore at the moment. TV Mobile has also launched their service for DVB terrestrial starting with the installation in certain public buses. MediaCorp is also assigned a DVB channel to simulcast 3 of its existing programmes. In the United States, the 746-806 MHz band has not been as highly utilised as the other analogue TV band. With the digital television implementation plan in place, the FCC has decided to license the band 746-806 MHz for mobile services. After the transition into digital broadcasting, FCC will also make 698-746 MHz available for other services. In Singapore, the broadcasting frequencies are highly congested. Over the years, IDA has only been able to convert 2 TV channels in the 470-485MHz band for trunk radio services. IDA will continue to study the trend on the convergence of services but is of the view that the transition from analogue to digital broadcasting will not happen in near future. This is partly due to lack of availability of TV sets and the cost of these TV sets. The use of digital technology with interactivity in traditional broadcasting spectrum has poised to create a new genre of converging multimedia services. IDA will review the use of broadcasting frequencies for these services. Short Range Devices The term “Short Range Devices” (SRD) is intended to cover radio transmitters which have low capability of causing interference to other radiocommunication equipment. Such devices are permitted to operate on a non-interference and no protection from interference basis. The following table shows the applications of short range devices working in the allocated bands and the maximum power or field strength that is allowed for the transmission: Application Operating Frequency Band

(i) Bluetooth/2.45GHz Bluetooth is a Personal Area Network (PAN) technology to connect wireless equipment such as computers, mobile phones and portable devices within a short distance of about 10m and supporting a data rate of 1Mbps. IDA has approved the use of Bluetooth enabled devices operating in 2400-2483.5 MHz, limiting the power (EIRP) to 100mW. (ii) Radio Local Area Networks (RLANs)/5GHz Radio Local Area Networks (RLANs) include networks using IEEE802.11 and HiperLAN standards. IDA has allocated the band 5150-5250 MHz for wireless access systems including RLANs subject to a power of 100mW. WRC2003 will consider common allocation of spectrum in the 5150-5350 MHz and 5470-5725 MHz bands for implementation of wireless access systems including RLANs. IDA is monitoring the sharing stud ies with existing services conducted by ITU-R study groups. Subject to the outcome of the studies by ITU-R and the decision in WRC2003, IDA may consider allowing implementation of the RLANs in the 5250-5350 MHz band. (iii) Radio Frequency Identification (RFID) RFID system uses low power radio signals to transfer data between an RFID tag and an RFID reader. Feedback from the industry has shown that there are demands for more spectrum in the range 820MHz to 920MHz for RFID. IDA will discuss with the industry in the later stage on the spectrum and power demand.

CONCLUSIONS The following table summarises the frequency bands that IDA is currently working on and the action to follow:

Frequency Range Action 174-230 MHz To plan for the convergence services

using DAB technology 410-430 MHz To re-plan for implementation of

digital trunk radio systems 494-790 MHz To plan for the convergence services

using DVB technology 1964.9-1979.7 MHz/2154.9-2169.7 MHz To review whether to issue a fourth

3G licence after Apr 2002 5250-5350 MHz To review the need to allocate

additional spectrum to Radio Local Area Networks

24.5-31.3 GHz

To review spectrum allocation via auction for implementation of Fixed Wireless Broadband Services when there is industry interest

The spectrum plans covered in this paper primarily focus on frequency allocations for public radiocommunication services as well as for applications commonly required by corporate and individual users. As technology evolves and new services are introduced, additional spectrum bands may be identified and existing ones refarmed. In achieving an effective spectrum plan, IDA will incorporate the industry’s feedback on spectrum allocation and usage in Singapore and update its spectrum plan periodically to take into account the latest market trends and technology developments.
