The Romanian city of Cluj-Napoca served as venue last 13-17 September for the 57th meeting of the Spectrum Engineering working group, chaired by Bruno Espinosa. Some 45 participants attended, including observers from the European Communications Office (ECO) and the European Telecommunications Standards Institute (ETSI).
Various documents were approved after the public consultation phase, namely:
- ECC Report on “Compatibility of Low Power Active Medical Implants (LP-AMI) in the 2600-3400 MHz Band, Particularly in the 2483.5-2500 MHz Band, with Existing Services”;
- ECC Report on “Compatibility Studies between RDSS and Other Services in the 2483.5-2500 MHz band”.
On the other hand, the following documents were provisionally approved and submitted for consultation:
- ECC Report on “Technical and Operational Requirements for the Possible Operation of Cognitive Radio Systems in the ‘White Spaces’ of the Frequency Band 470-790 MHz”;
- ECC Report 157 on “The Impact of Radar Spurious Emissions on Other Radiocommunication Services/Systems”;
- ECC Report on “The Impact of 26 GHz SRR Applications Using ULTRA-WIDEBAND (UWB) Technology on Radio Services”;
- ECC Report on “Conditions for Possible Co-existence Between HAPS Gateway Links and other Services/Systems in the 5850-7075 MHz Band”;
- ECC Recommendation (10)XY on “Guidelines for Block Allocation for Fixed Wireless Systems in the Bands 24.5-26.5GHz, 27.5-29.5GHz and 31.8-33.4GHz”.
The meeting also served to discuss the work of WG SE project team (PT) 7, which is working on methods to co-ordinate between GSM-R and the mobile networks (GSM, UMTS/LTE). PT19 finalised in turn a new recommendation for FWA which uses the content of the following recommendations:
- ERC/REC/(00)05 “Use of the Band 24.5–26.5 GHz for Fixed Wireless Access”;
- ERC/REC/(01)03 “Use of Parts of the Band 27.5–29.5 GHz for Fixed Wireless Access (FWA)”;
- ECC/REC/(04)06 “Guidelines for Block Allocation for Fixed Wireless Systems in the Band 31.8–33.4 GHz”.
As a result of the approval of CEPT Report 39 (response to the 2 GHz mandate), comments were received which noted that the studies did not analyse compatibility between ECN and MSS in 2 GHz (1980–2010 MHz and 2170-2200 MHz). Given that the CGC/MSS terminals linked to the satellites (in the 1980-2010 MHz band) present signal levels greater than the BTS of CGC, and given that standards exist with earth station specifications that are different from those used in DEC/(06)09, the group will examine the compatibility of ECN and CGC/MSS.
A proposed report was also presented concerning the implementation of WSD (Cognitive Radio in UHF White Spaces) which considered two control techniques: sensing and geo-localisation. Note that same contains in its section 11 a list of issues that should be examined in the future. This report was submitted for public consultation.
The next Spectrum Engineering working group meeting will be held on 24-28 February 2011 in Cardiff, the United Kingdom.
