The 69th meeting of the ECC Spectrum Engineering working group (WG SE) was held in Salzburg, Austria, last 26-30 January. The 54 participants included the observer from the European Communication Office (ECO) along with representatives from industry and operators (APWPT, ANITEC, Digital Europe, Dominique Jeaan Rolfo Conseil and also Defense – France, Ericsson, FBConsulting Sarl, Inmarsat Ventures Limited, Inquam Deutschland GmbH, SES, Telenor, Thales Alenia Space and Wi-Fi Alliance).
The following documents were approved after the consultation phase:
- revision of Recommendation ERC/REC 12-11 on radio frequency channel arrangements for fixed service systems operating in the bands 48.5 50.2 GHz and 50.9 52.6 GHz;
- revision of Recommendation ERC/REC 12-12 on radio frequency channel arrangement for fixed service systems operating in the band 55.78 57.0 GHz;
- ECC Report 226 on unwanted emissions of IRIDIUM satellites in the band 1610.6 1613.8 MHz, monitoring campaign 2013;
- ECC Report 227 on compatibility studies for mobile/fixed communication networks (MFCN) supplemental downlink (SDL) operating in the 1452-1492 MHz band;
- ECC Report 228 on compatibility studies between intelligent transport systems (ITS) in the band 5855-5925 MHz and other systems in adjacent bands.
The following documents were approved on a preliminary basis and forwarded for public consultation:
- Draft ECC Report 232 on compatibility between fixed satellite service uncoordinated receive Earth stations and the fixed service in the band 17.7-19.7 GHz;
- Draft ECC Report 233 on adjacent band compatibility studies for aeronautical CGC systems operating in the bands 1980-2010 MHz and 2170-2200 MHz;
- Draft ECC Report 234 on analyses of LDC UWB mitigation techniques with respect to incumbent radiocommunication services within the band 3.1 to 3.4 GHz;
- Draft ECC Report 235 on assessment of the feasibility of the possible joint use, on a long term basis, of the adjacent bands 5.925-6.425 GHz and 6.425-7.125 GHz for P-P links.
Work by WG SE’s project team on Spectrum Engineering 7 (PT SE7) is under way regarding compatibility for introduction of the following: - programme making and special events (PMSE) equipment in the 694-703 MHz and 733-758 MHz bands;
- public protection and disaster relief (PPDR) in the 698-703 MHz/753-758 Mhz, 733-736 MHz/788-791 MHz or 733-743 MHz/748-758 MHz bands;
- mobile/fixed communications network (MFCN) – supplemental downlink networks in the 733-758 MHz band;
- digital terrestrial television (DTT) operating below 694 MHz.
A set of contributions must still be considered and the respective conclusions reconciled.
Regarding studies to introduce PPDR (based on LTE-400 long term evolution technology) in the 410-430 MHz and 450-470 MHz bands, the work has progressed and is nearly finished. Both studies (700 MHz and 400 MHz) will be presented at the next WG SE meeting for preliminary approval and forwarding for public consultation.
Lastly, PT SE7 was mandated to study the introduction of voice PMSE in the 1350-1400 MHz band.
Regarding the fixed service work of Spectrum Engineering project team 19 (PT SE19), beyond finishing revision of a set of recommendations, a report on the possibility of merging the two 6 GHz sub-bands (5925-6425 MHz and 6425-7125 MHz) into a single channel was completed.
With respect to the work of Spectrum Engineering project team 24 (PT SE24) concerning low power short range devices (SRD), the work associated to the mandate of 5 GHz for wireless access systems/radio local area networks (WAS/RLAN) is notably not yet complete. Guidelines were received from CEPT’s ECC and from the European Commission (EC), specifically phasing the work to be completed. The EC nevertheless maintains its position on the 2016 deadline for finishing all the work.
Regarding satellite matters pertaining to Spectrum Engineering project team 40 (PT SE40), a report was completed concerning the operation of complementary ground component (CGC) stations in the 1980-2010 MHz and 2170-2200 MHz bands.
The next WG SE meeting will be held on 4-8 May 2015 in Finland.
