The 71st meeting of the ECC’s Spectrum Engineering working group (WG SE) took place from last 28 September to 2 October in the French city of Lyon, attended by about 54 participants, including the observer from the European Communications Office (ECO) and representatives of industry and operators (ANITEC, APWPT, Airbus Defence and Space, Arqiva, Car2Car Communication Consortium/FBConsulting Sarl, EBU, EUMETNET/ESA/EUMETSAT, Ericsson, IRT, Robert Bosch and TeliaSonera).
The following documents were approved, after the consultation phase:
- Draft ECC Report 239 on compatibility and sharing studies for BB PPDR operating in the 700 MHz range;
- Draft ECC Report 240 on compatibility studies regarding Broadband PPDR and other radio applications in 410-430 and 450-470 MHz and adjacent bands.
The following documents were provisionally adopted and forwarded for public consultation:
- Draft ECC Report 243 on wireless video links in the frequency bands 2700-2900 and 2900-3400 MHz;
- Draft ECC Report 245 on compatibility studies between PMSE and other systems/services in the band 1350-1400 MHz;
- Draft ECC Report 244 on compatibility studies related to RLAN in the 5725-5925 MHz band;
- Draft ECC Report 246 on wideband and higher DC short range devices in 870-875.8 MHz and 915.2-920.8 MHz (companion to ECC Report 200);
- Draft ECC Report 247 on description of the software tool for processing of measurements data of IRIDIUM satellites at the Leeheim station.
WG SE’s Spectrum Engineering project team 7 (PT SE7) continues its work regarding compatibility for the introduction of programme making and special events (PMSE) in the 1492-1525 frequency band. A number of contributions must still be considered and the respective conclusions reconciled, which is expected to be done by this coming January. The studies on the 1350-1400 MHz frequency band have been completed and the report provisionally approved.
Regarding the work of Spectrum Engineering project team 19 (PT SE19) in the scope of fixed service, it is drawing up the report on a questionnaire that was sent out regarding eventual use of multiple input multiple output (MIMO) technologies for fixed service, given the interest shown by manufacturers and operators. Also approved were two new tasks with a view to developing channels and requisites for fixed service in the 92-114.5 GHz and 141-174.8 GHz frequency bands.
Regarding work involving low power short range devices (SRDs) under way in Spectrum Engineering project team 24 (PT SE24), notable work is being done in the scope of the 5 GHz mandate for wireless access systems (WAS)/radio local area network (RLAN) and the first part of the respective report has been provisionally approved. Some matters are still pending, specifically the analysis of mitigation techniques (being done by the European Telecommunication Standards Institute (ETSI)) and the eventual use of long term evolution – unlicensed (LTE-U)/long term evolution – licence assisted access (LTE-LAA). This project team has also been assigned the task of reanalysing the studies on SRDs and broadband direct air-to-ground communications – time division duplex mode (BB-DA2GC TDD) in the 1900-1920 MHz frequency band.
The next WG SE meeting will be held on 25-29 January 2016 in the Netherlands.
