PT SE 19 - Copenhagen

Copenhagen hosted on 6-8 September the 36th meeting of the group PT SE19, which covers fixed service issues.

ECC Draft Report 91 on the ?Compatibility of Earth Stations on Board Vessels Transmitting within the Gaps in the CEPT Fixed Service Channel Plan for the Lower 6 GHz Band (5925-6425 MHz)?, which was subject to public consultation for two months ending last 1 August, was revised based on the comments received and submitted to the Spectrum Engineering working group (WG SE) for final approval.

The draft ECC Report on ?Sharing and Compatibility Studies between BWA and Other Services/Systems in the 3.4 - 3.8 GHz Band? was finalised and submitted to WG SE to be adopted for public consultation.

Regarding aspects of MWA (mobile wireless access) for co-existence with BWA (broadband wireless access) cells in 3.5 GHz, after lengthy debate a decision was made to maintain the principle set out in ECC/REC 04-05 to determine the various frequency blocs. It was stressed that the Block Edge Mask concept, mainly for central stations, will ensure good results in a context of mobility. It was also deemed necessary to carry out studies to evaluate the case of TS-TS (terminal station) co-existence in order to assess possible consequences in a mobility scenario. Motorola offered to carry out this work, but as same will take approximately two months, WG SE will be asked to extend the period so as to complete those studies by this coming November.

Following the assignment of a new working item to PT SE19 at the last WG SE meeting ? MGWS (Multiple Gigabit Wireless Systems) co-existence in 60 GHz ? debate centred around the kind of licensing to be applied to such systems, which will have to be decided in the future. Regarding the question of compatibility, same will also have to be investigated, with contributions on this topic expected for the next group meeting. SE 19 was also asked to validate the technical parameters of fixed service in the 5.9 and 64 GHz bands, to carry out studies on compatibility with other systems in those bands; the group responded to the requests.

The European Telecommunciations Standards Institute (ETSI) proposed the introduction of 56 MHz channels (the idea is to aggregate adjacent 28 MHz channels) in various fixed service frequency bands, specifically in bands from 3 to 13 GHz, where such channelling is not possible bearing in mind the ERC/ECC recommendations. It was concluded that the presented proposal seemed viable. A decision was also made to ask WG SE for its opinion on a number of subjects.
