PT SE 19 - Copenhagen

/ Updated on 30.08.2006

Project team PT SE19 of the working group on Spectrum Engineering (ECC WG SE), met on 20-21 April in Copenhagen; its mission centres on fixed service (FS) issues such as:

- preparation of harmonised frequency plans for FS;

- studies on new FS technologies;

- compatibility studies between FS and other services;

- co-ordination of relevant activities with the Radiocommunications Sector of the International Telecommunications Union (ITU-R).

Among other issues, the participants discussed the co-existence of fixed wireless systems (FWS) in the 3.4-3.6 GHz and 3.6-3.8 GHz bands.

A Correspondence Group (CG) had been set up at the last meeting, with the mission of finalising an ECC recommendation on FWS co-existence in the 3.4-3.6 GHz and 3.6-3.8 GHz bands. As a result of the work accomplished by this CG, the final version of an ECC recommendation was presented for submission to ECC WG SE for approval.

Another subject in focus was co-existence between multipoint (MP) systems in the 32 GHz band.

The French administration had at the previous meeting been invited to submit a frequency plan for the band between 31.8 and 33.4 GHz. The proposal submitted was revised by SE19 and now passes on for consideration by ECC WG SE.

The equivalent isotropic radiated power (EIRP) limits in the 58 GHz band were likewise debated. During the meeting the ECC report was revised section by section. The version resulting from this work was approved for submission to ECC WG SE. Approval of this report will enable EIRP to be increased to 58 GHz in FWS systems.

Also agreed was a proposal to alter ECC/REC12-09, to be presented in the WG SE.

Regarding the FWS frequency plans in the frequency band between 64 and 66 GHz, the work being prepared by the CG set up for that reason in the last meeting is still under way. But it has already been agreed that the spectrum in question will be divided into 66 blocs of 30 MHz, with 2 blocs of 10 MHz as guard band.

The Italian representative presented a document proposing the development of frequency plans for future FWS between 71 GHz and 76 GHz.

The next meeting will be held on 14-15 September.
