25-27 August 2014 – The Spectrum Engineering Project Team SE 24, responsible for compatibility studies related to Short Range Devices (SRD), met in Biel, Switzerland
SE 24 has finalised the draft ECC Report assessing the coexistence between Intelligent Transportations Systems (ITS) and road tolling applications around 5.8 GHz and containing some new studies performed on the impact from ITS into the Fixed service above 5.925 GHz. The draft Report will be sent to Working Group Spectrum Engineering (WG SE, 15-19 September 2014) for public consultation. The Report sets out the conditions to relax the ITS unwanted emissions limitations resulting from the previous studies in ECC Report 101.
SE 24 has made some progress on the compatibility studies related to Radio Local Area Networks (RLANs) in the band 5725-5925 MHz. SE 24 finalised the part on the compatibility between RLAN and Direct-Air-to-Ground Communications (DA2GC) and identified possible mitigation techniques for the coexistence between RLAN on the one hand and terrestrial systems (ITS, road tolling, Broadband Fixed Wireless Access (BFWA)) on the other. SE 24 further developed its analysis on the aggregate interference from RLAN into the fixed-satellite service (FSS) and initiated a sensitivity analysis to assess the impact from factors such as antenna discrimination and clutter attenuation. A summary was drafted to provide the preliminary results and the main areas for further work to the other groups involved in the ECC's work on 5 GHz RLANs (namely, FM 55 and CPG PTD).
SE 24 considered the responses received during the public consultation on the draft ECC Report 222 on the compatibility studies related to helicopter applications in the band 76-79 GHz. This resulted in a revision of the draft ECC Report 222 which is ready for consideration in WG SE for final approval for publication.
Details on these items and on the other activities are available on the SE 24 webpage.
26-27 August 2014 – The Spectrum Engineering Project Team SE 7, responsible for compatibility and sharing issues of the mobile systems (except IMT), met in Brest, France
SE 7 has finalised the draft ECC Report on the sharing conditions between Mobile/Fixed Communications Networks (MFCN) Supplementary Down-Link (SDL) and the other applications using the 1452-1492 MHz band. The report will be submitted to the WG SE meeting in September 2014 for approval for public consultation.
SE 7 addressed responses received during the public consultation on the draft ECC Reports 220 (compatibility studies in the unpaired 2 GHz bands) and 221 (compatibility between Programme Making and Special Events (PMSE) and MFCN in the 700 MHz band). As a result, revised versions of both draft ECC Reports were developed and will be submitted to the next WG SE for final approval for publication.
SE 7 also continued work on the draft ECC Report on compatibility studies for Public Protection and Disaster Relief (PPDR) applications at 400 MHz and started its considerations on PPDR in the 700 MHz band.
Details on these items and on other activities are available on the SE7 webpage.
26-27 August 2014 – The Numbering and Networks Project Team FNI, responsible for future numbering issues, met at the ECO, Copenhagen, Denmark
Work on Extra-Territorial Use of E.164 Numbers continues within PT FNI. Achieving consensus on developing an appropriate deliverable remains challenging. This meeting highlighted the need for greater transparency in current and future extra-territorial use and a draft framework for a public workshop (planned for 27 January 2015) on the subject was developed and will be discussed further at the next meeting in November.
Good progress was made on revising an ECTRA Recommendation from 1998 on ‘Guidelines for Fundamental Changes to National Numbering and Dialling Plans’. The review was motivated by the need to update this deliverable given the significant technical, regulatory and policy changes that have taken place since the deliverable was first conceived. It is planned to have the draft deliverable ready for public consultation at the next meeting of WG NaN in October 2014.
Further information on these items and on other activities is available on the PT FNI webpage.
27-28 August 2014 – The Spectrum Engineering Project Team SE 19, dealing with fixed service (FS), met in Bucharest, Romania
SE 19 has completed its work towards the review of the FS channel arrangements in the 50, 52 and 55 GHz bands to include wider channel sizes. As a result, SE 19 has developed a draft revision of ERC Recommendation 12-12 (for the 55.78-57 GHz band) and of ERC Recommendation 12-11 (which now covers the bands 48.5-50.2 and 50.9-52.6 GHz).
These draft deliverables will be submitted to the next WG SE meeting (15-19 September 2014) for approval for public consultation.
SE 19 has initiated the compatibility studies related to the possible use of the band 5850-5900 MHz by Maritime Broadband Radio (MBR) links as proposed in the ETSI System Reference Document TR 103 109.
SE 19 considered the responses from 19 CEPT administrations to a questionnaire on the procedure for handling Multiple Input Multiple Output (MIMO) technology on fixed links and proposes, as a result, a new work item to develop an ECC Report providing guidelines on how to plan MIMO Fixed Service links.
More details are available on the SE19 webpage.
27-29 August 2014 – The Frequency Management Short Range Devices Maintenance Group (SRD/MG) met in Biel, Switzerland
Concerning the Recommendation 70-03, SRD/MG agreed to update two annexes: Annex 2 with a change concerning the entry for networked SRDs in 870-875.6 MHz and Annex 5 with a new entry for a 76-79 GHz anti-collision radar application for helicopters. This proposal will be considered by Working Group Frequency Management (WG FM) in October for approval for public consultation.
SRD/MG completed its work on the update of the conditions of use of the band 5855-5905 MHz for Intelligent Transportation Systems (ITS). This led to draft revisions of ECC Decision(08)01 and ECC Recommendation(08)01. Both documents will be submitted to WG FM for approval for public consultation.
SRD/MG has also started the process of identifying the issues to be covered in response to the EC Mandate for the sixth update of the EC Decision on SRDs.
For further details on these items and other activities, see the SRD/MG webpage.
28-29 August 2014 – The Spectrum Engineering Project Team SE 40, responsible for space services compatibility studies, met in Brest, France
SE 40 finalised its work on the new draft ECC Report containing and analysing the measurements campaign carried out by the Leeheim station in November 2013 on the Iridium unwanted emissions in the Radio Astronomy frequency band 1610.6-1613.8 MHz. The results are consistent with those obtained from similar measurements carried out in 2010 and reported in ECC Report 171. The draft ECC Report will be submitted to the next WG SE meeting (15-19 September 2014) for approval for public consultation.
SE 40 also continued its work on the compatibility studies dealing with the possible introduction of aeronautical Mobile Satellite Services (MSS) Complementary Ground Components (CGC) systems operating in the bands 1980-2010 MHz and 2170-2200 MHz.
