CPG PT2 and PT3 - Toulouse


/ Updated on 30.08.2006
The meetings of groups PT2 and PT3 of the Conference Preparatory Group (CPG) were held on 18-21 April in Toulouse, France, with the aim of preparing the European position for the upcoming 2007 World Radiocommunications Conference (WRC-07). 
 
PT2 is responsible for questions involving space science services (satellite earth exploration, space research and satellite weather forecasting) and terrestrial services. 
 
The meeting saw approval of the revision and consequent updating of the Briefs with results from the most recent meetings of the groups in the Radiocommunications Sector of the International Telecommunication Union (ITU-R) responsible for each WRC-07 agenda item. Regarding the draft European common proposals (ECPs), the following developments occurred: 
 
- Item 1.2 (on sharing criteria in the 36-37 GHz bands), the possible extension of 100 MHz of satellite weather service (METSAT) in the 18 GHz band and revision of the sharing criteria in the 10.6-10.68 GHz band) ? for the time being the ECP only considers the extension of 100 MHz of spectrum to METSAT, currently in the 18.1-18.3 GHz band, proposing the 18.1-18.4 GHz band;
 
- Item 1.3 (on updating the status of radio-localisation service and the possible extension of 200 MHz of spectrum to earth exploration by satellite service (EESS) in the 9 GHz band) ? the ECP proposes promoting from secondary to primary status radio-localisation service in the 9000-9200 MHz bands and 9300-9500 MHz bands and the extension of 200 MHz (9300-9500 MHz band) to EESS (currently 9500-9800 MHz), only for systems that need bandwidths bigger than 300 MHz;
 
- Item 1.7 (on sharing criteria between mobile satellite service (MSS) and mobile services and space research in the L band (1668-1675 MHz) ? there is still no draft ECP;
 
- Item 1.17 (on allocating spectrum to MSS feeder links around 1.4 GHz) ? the ECP proposes withdrawing allocation of the 1390-1392 MHz and 1430-1432 MHz bands to MSS feeder links, an allocation decided at WRC-03;
 
- Item 1.20 (on revising the power limits for undesirable emissions from active services to better protect passive services) ? there is still no ECP.
 
PT3 is the group responsible for questions involving fixed, satellite fixed and aeronautic radionavigation services.
 
This meeting saw approval of the revision and consequent updating of the Briefs, as well as the draft ECPs for the following WRC-07 agenda items:
 
- Item 1.5 (on spectrum needs for broadband telemetry and aeronautic telecommand applications) ? spectrum requirements were identified for about 105 MHz for such applications, as long as limited to flight testing; the draft ECP proposes accommodating those requirements in the 5 GHz band (5030-5250 MHz), though there is still no CEPT consensus on this topic;
 
- Item 1.6 (on spectrum identification between 108 MHz and 6 GHz for aeronautic mobile en route service (AM(R)S)) ? the draft ECP proposes allocating the 112-117.95 MHz, 960-1164 MHz and [5030 or 5091]-5150 MHz bands with primary status at comprehensive level; there is also no consensus on this topic, in so far as there is a certain overlap with the topic of item 1.5 described above, mainly due to the 5 GHz band;
 
- Item 1.8 (on sharing criteria for high altitude platform (HAP) frequency bands) ? a probable new CEPT position is currently being discussed, defended by the United Kingdom, with a view to allocating the 23/31 GHz bands to HAPs at comprehensive level; those bands are currently allocated only to the Region 3 (Asia) countries. There is still no draft ECP;
 
- Item 1.18 (on revising the power limits for satellite systems in highly inclined elliptical orbits (HEO) applicable in the 17.7-19.7 GHz band) ? an ECP was approved with proposals to revise the current power flow density limits included in article 21 of the Radio Regulation and which are applicable to such satellite systems for the protection of fixed service;
 
- Item 1.19 (on spectrum requirements in harmonised FSS bands for internet applications by global broadband systems) ? a draft ECP was approved which proposes making no regulatory modification, as the frequency bands WRC-03 allocated for high density fixed satellite service (HDFSS) applications are adequate for the intended applications. 
 
These groups are next scheduled to meet in October 2006 in Vilnius, Lithuania.
