The following documents were adopted and forwarded for public consultation:
- Draft ECC Report 206 on ''Compatibility studies in the band 5725–5875 MHz between SRD equipment for wireless industrial applications and other systems'';
- Draft ECC Report 207 on ''Adjacent band co-existence of SRDs in the band 863-870 MHz in light of the LTE usage below 862 MHz'';
- Draft ECC Report 208 on ''Impact of RFID devices on radio services in the band 13.56 MHz'';
- Draft ECC Report 209 on ''Compatibility/sharing studies related to Broadband Direct Air-to-Ground Communications (DA2GC) in the frequency bands 1900 1920 MHz / 2010–2025 MHz and services/applications in the adjacent bands'';
- Draft ECC Report 210 on ''Compatibility/sharing studies related to Broadband Direct Air-to-Ground Communications (DA2GC) in the frequency bands 5855 5875 MHz / 2400–2483.5 MHz and 3400–3600 MHz'';
- Draft ECC Report 211 on ''Technical assessment of the possible use of asymmetrical point-to-point links'';
- ECC/REC(14)01 ''Radio frequency channel arrangements for fixed service systems operating in the band 92-95 GHz''.
New tasks were created, specifically:
- technical analyses for the introduction of equipment for programme making and special events (PMSE) in the 2700-2900 MHz, 2900-3400 MHz, 4400-5000 MHz, 7110-7250 MHz, 7300-7425 MHz and 8460-8500 MHz frequency bands, a task assigned to WG SE project team 7 (PT SE7), responsible for matters concerning compatibility and sharing of mobile systems, except international mobile telecommunications (IMT);
- introduction of PMSE in the 1492-1518 MHz and 1518-1525 MHz bands, bearing in mind the protection of mobile satellite service (MSS), a task assigned to WG SE PT 21 (PT SE21), responsible for matters concerning unwanted emissions;
- revision of the fixed service recommendations ECC/REC(01)04, ERC/REC(12)10, ERC/REC(12)11 and ERC/REC(12)12, on the introduction of broader channels, a task assigned to WG SE PT 19 (PT SE19), responsible for fixed service issues;
- introduction of cochlear implants to operate in the 2483.5-2500 MHz frequency band, a task assigned to WG SE PT 24 (PT SE24), responsible for matters concerning short range devices;
- technical analyses of operation of Transport and Traffic Telematics/Dedicated Short Range Communications (TTT/DSRC), i.e. toll payments operating in the 5805-5815 MHz band, a task assigned to WG SE PT 24 (PT SE24);
- radar operation in helicopters for landing assistance, in the 76-77 GHz band, a task assigned to WG SE PT 24 (PT SE24);
- use of earth stations on mobile platforms (ESOMP) operated with non-geostationary satellite orbit (NGSO) networks operating in the 25.5-29.1 GHz and 29.5-30 GHz bands, a task assigned to WG SE PT 40 (PT SE40, responsible for issues concerning satellite service compatibility.
Support work was completed for the response to the European Commission (EC) mandate on PMSE in the duplex band of the global system for mobile communications (GSM) in the 1785-1805 MHz bands. Studies were also begun to introduce PMSE in additional bands (see new tasks of PT SE7).
Note that in the scope of PT SE7 – PMSE, by the beginning of 2014 support studies should be completed for the response to the 2 GHz mandate for the digital enhanced cordless telecommunications (DECT) system; for PMSE; for public protection and disaster relief (PPDR); for DA2GC and also for low power short range devices (SRD). Regarding the introduction of DA2GC in the 2 GHz band and 5.8 GHz band, two reports were approved for public consultation (see PT SE44).
Note also that the work in fixed service continues, specifically:
- finalisation of work to introduce asymmetry in channels (DL reinforcement) – Draft ECC Report 211 has been submitted for public consultation;
- analysis of the possibility of introducing smaller channels (between 25 kHz and 2 MHz in the centre gaps or guard bands of the fixed wireless system (FWS) channels in the 3-15 GHz band, i.e. if possible to transfer links currently operating in the 1.4 GHz band to other bands.
Lastly, studies were completed on the introduction of SRD, radio-frequency identification (RFID) equipment, intelligent measurement equipment (smart metering) and intelligent networks (smart grid) in the 870-876 MHz/915-921 MHz bands. The conclusions indicate the possibility of introducing various kinds of SRD, as long as some generic requisites are met; there is nevertheless a need to safeguard four channels for RFID operation in the 915-921 MHz band. SRD operation in the 863-870 MHz band was also examined, bearing in mind the introduction of long term evolution (LTE) in the 800 MHz band; the conclusions indicate more restriction in terms of SRD operation.
The next WG SE meeting will be held on 27-31 January 2014 in Sesimbra, Portugal.
