[STDS-802-11] Decision from the UK Ofcom consultation on SRD (5.1 GHz, 5.9 GHz, UWB, sub 1-GHz band, 24 GHz)

--- This message came from the IEEE 802.11 Working Group Reflector ---
Dear 802.18 members,
cc 802.11 and 802.15 members,

Following its consultation “Proposals to amend the authorisation conditions for the use of certain Short-Range Devices” completed in July 2022, UK Ofcom released a statement on 28 September 2022 and determined to proceed on the following changes:

Please note that Ofcom has revised the comment closing date from Thursday 30 June 2022 to Monday 4 July 2022.   Nevertheless, our 802.18 internal deadline for review and approval remains unchanged, i.e., Thursday 16 June 2022.

Dear 802.18 members,
cc 802.11 and 802.15 members,

UK Ofcom began a consultation today entitled "Proposals to amend the authorisation conditions for the use of certain Short-Range Devices", which seeks public opinion on the following 4 items

1)  Provide additional spectrum for safety-related Intelligent Transport System (ITS)
2)  Liberalise the use of 5150 to 5250 MHz for Wireless Access Systems including RLAN
3)  Liberalise some of the technical conditions for some Ultra-Wideband (UWB) devices:
4)  Make some technical and minor editorial changes to SRD applications in the 870/915 MHz bands
5)  Close the 24 GHz Automotive Short-Range Radar (SRR) band to new applications (which I will not cover in the rest of this email)

For 1), UK Ofcom proposes to follow the EU Decision 2020/1426 that provides an additional 20 MHz spectrum for safety-related ITS, i.e., from the current 5875~5905 MHz to the proposed 5875~5925 MHz.

For 2), UK Ofcom proposes to follow the EU Decision (04)08 that
[a] allow mobile/nomadic outdoor use but not fixed outdoor use in 5150~5250 MHz
[b] allow airborne use in 5170~5250 MHz

UK Ofcom also uses this opportunity to clarify that DFS and TPC only applies to 5250~5350 MHz only.  In other words, DFS and TPC are not required in 5150~5250 MHz.

For 3), UK Ofcom proposes to follow the EU Decision 2019/785 that
[a] set out the technical requirements and power limit (i.e., -65 dBm/MHz) for material-sensing devices, including building material analysis, in 8.5~10.6 GHz
[b] introduce a trigger-before-transmit mitigation technology for operating vehicle keyless entry systems enables more secure low-power keyless access to cars in 3.8~4.2 GHz and 6~8.5 GHz

For 4), UK Ofcom proposes to follow the CEPT Report 77 that relax some of the requirements applicable to fixed devices in 870~874.4 MHz, 917.3~918.9 MHz, and 917.4~919.4 MHz:
[a]  relax the requirement that all such devices be controlled by network access points, and propose instead that only mobile and nomadic devices should be controlled
[b] make technical changes to introduce a minimum channel bandwidth of 600 kHz in 917.4~919.4 MHz

The comment submission deadline is 5pm London local time, Thursday 30 June 2022.   If you would like IEEE 802 EC to submit a comment to this consultation, our internal 802.18 deadline to review and consider approval of any proposed comment is Thursday 16 June 2022.  

Our 802.18 official document - the status of ongoing consultations - is also updated accordingly to include information of this new consultation:
