Tasks:

Produce a report of FWA sharing with other services in band C.Produce draft UK contributions (to be processed through the normal RA committee’s) for potential CEPT sharing studiesDevelop a strategy on how to promote the findings of the sharing study.Identify bottlenecks and propose resolutions concerning the finalisation of DFS parameters / values / implementation etc...

Sharing with Radar

Similar situation to band B

DFS-67dBm for devices greater than 1 Wcould change...

Sharing is possibleMOD have asked for exclusion zones around operational sites (less than 10).

Sharing with FSS

Need to limit the numbers of FWA or the EIRP towards the satellite

So far sharing seems feasible for a 2W EIRP + TPC FWA transmitterWe are expecting more sharing work for higher power systemsEIRP spectral density mask to be definedTPC

at least 12dB dynamic range

Sharing with RTTT

Need to protect the Road Side Unit

more work is required Very low threshold detection required and will need to be looked at TPCNotch out the RTTT band (20MHz) simple solution

Sharing with ENG/OB

there is a need to protect some receiving sites.

Do we need to protect all 3 channels at each site. Is DFS useful for protecting P-P FDD systems effect of TPC on results

UK SE38 duties

Preparation of UK contributions to SE38. It is expected that this will mostly consist of the sharing studies on which UK policy has been basedPreparing a UK view for SE38 meetings, taking account of other relevant UK groupsReports to UK WG SE, including proposing the UK line to be taken in WG SE on SE38 issues

Conditions for FWA use of Band C

MoD approval essentialConcerns over Road Transport and Traffic Telematics to be addressedContinued access to useful spectrum for ENG-OB to be addressedFWA/FSS sharing issues addressed,Introduction of light Licensing regime essential in the beginning.

Other services

Studies so far indicate that some of the technical measures proposed will satisfy the most requirements of RTTT, FSS and ENG-OB users of the band. But there may be some operational restrictions on all the services involved needed.
