EC mandate to ECC to review the technical annex in EC Short Range Devices Decision

• The EC SRD Decision is mandatory for all member states to implement.

• The Annex in the Decision covers different tables for specific SRD use in a number of different bands from kHz to 60 GHz including:

• Generic or Non Specific SRD use • Alarms and Social Alarms• Inductive Applications• Active Medical Implants• Wireless Audio Applications

• Changes been approved by ECC and sent to EC. Decision likely to be amended and approved in either October or December 07.

• Member States usually given 6 months to implement from publication date.

Update on UWB activities in UK/Europe

ETSI standard in public enquiry stage has brought out an issue with EC Decision.

Wi-Media statement to UK consultation“The draft regulation contains a definition of to be used in the assessment of peak power measurements and specifies a correction factor of 20log(50/x) db where bandwidths other than 50MHz have been used for measurement. Whilst WiMedia appreciates that the format of this correction is drawn form Article 2 of the EC decision, we would draw OFCOM’s attention to the fact that such a correction is valid only for UWB technologies that are pulse based. The technology used in WiMedia Alliance products is Orthogonal Frequency Division Multiplexing (OFDM) modulation which is Gaussian noise like in nature(1). Consequently a correction based on 10log(50/x) would be a more appropriate in this case. This technology distinction has been recognized by the ETSI and provision has been made in the draft EN for both classes of UWB devices to assure fair product assessment as a prerequisite to market access.”

Update on ITS activities in UK/Europe

• ECC draft response to EC Mandate submitted including an Impact Assessment • Final Response to be approved @ WGFM meeting September, possible allocations in these bands to ITS

5850 – 5925 MHz

63.0 – 64.0 GHz

• Response to be discussed @ EC RSC December

Possible outcome is EC Decision for both or any of the bands mentioned.

Update on Multi GBit systems in 60GHz• ECC WGSE have completed a number of Reports • Competing Demand for Spectrum between

Fixed PtP links (57 – 66 GHz)WPAN/WLAN (57 – 66 GHz)

ITS (63.0 – 64.0 GHz)

• Discussion on allocations to take place @ WGFM

At present strong lobby in UK/Europe from both PtP and ITS communities

• Ofcom LEFR consultation promotes possibility of generic LE allocations in these bands.

Delivering on the vision of the SFR

• In the SFR we suggested an increase in LE spectrum of 1%, relating perhaps to an additional 200MHz at 5GHz

• Our recent measurements suggest a low level of utilisation of LE spectrum, especially in the existing 5GHz bands

• Hence, there seems little reason at this stage to extend the LE allocation in these bands

• We will keep this under review but at present do not expect to provide additional LE spectrum by 2010 at 5GHz

Slide 15

Licence exemption may be appropriate in some cases to maximise the efficient use of the spectrum

• Ofcom’s main objective is to maximise the efficient use of the spectrum – measured in terms of economic efficiency

• There are two reasons why making a band licence-exempt might achieve this

1: Higher economic value

Making a band LE might result in more economic value than licensing it. To test this we need to make a forward prediction of use under licensed and LE usage

2: Supply exceeds demand

In some bands, particularly at very high frequencies, there is more supply than demand and hence licensing imposes an unnecessary bureaucratic burden

Slide 16

A preference for international coordination

• In general, we prefer the market to achieve coordination and harmonisation through trading and change of use of spectrum in multiple countries

• However, LE spectrum requires regulatory intervention to identify the spectrum and establish the rules for its operation giving little opportunity for market forces to modify parameters

• As a result, it would generally be preferable for regulators to coordinate internationally as far as possible in order to achieve harmonised strategies and allocations

• We will work with CEPT, EC and ITU to aim for a harmonised approach to LE spectrum as far as possible although equally we will not unduly delay our initiatives if harmonisation appears difficult to achieve

Slide 17

doc.: IEEE 802.18-07/0060


Our proposals fall into three key areas

Better use of LE spectrum

LE above a given frequency

LE below a given power level

Adoption of shared LE bands but with zoning by

power and use of politeness protocols

Above 60GHz most of the spectrum can be

made LE

At similar power levels to UWB usage can be

made exempt

Slide 20

LE above a given frequency• At higher frequencies the spectrum

is increasingly little used

– This is due to the poor propagation and high equipment costs

• The probability of interference is low because of the low range of devices

• This results in an area of spectrum where supply exceeds demand and hence licensing is unnecessary

• There is some use in these bands, and given that there is excess supply we propose to leave existing use unchanged 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105

Timescales for UK consultation on consolidated proposals for Licence Exemption

• Consultation due out in September on what we will be proposing to implement.

• Will include any updates as a result of EC SRD Decision changes.

• Only LEFR proposal likely to be included in the short term is LE allocations around 60GHz.
