Russia expressed concerns about the maximum power spectral density level of -41.3 dBm/MHz, in particular in bands used by FSS, and indicated that they intend to further examine the studies and comment during the public consultation.
WG FM adopted for public consultation draft ECC Recommendation on LT2 (see Annex 20).
5.6.4.Location Tracking Application for Emergency Services (LAES) in disaster situations
The Chairman of FM PT47 presented the proposals from FM PT47 concerning LAES (see doc. FM(11)079 section 1.1.1).
The Liaison Statement from WG SE on the result of compatibility study on specific UWB Applications in the bands 3.4 - 4.8 and 6 - 8.5 GHz (LAES, LT2 and LTA) was introduced (see doc. FM(11)099). WG SE underlines that the draft ECC Report on specific UWB Applications approved for public consultation concludes that separation distances (up to 20 km for outdoor LAES and up to 7 km for indoor LAES) should be established around victim stations of radio services. Concerns were expressed within WG SE with regard to the protection of the existing services in emergency situations where the implementation of the separation distances may be difficult. LAES are considered as SRD and should operate on non-interference non-protection basis. Therefore, WG SE would like to invite WG FM to consider the above mentioned situation while developing appropriate regulations for LAES.
The Chairman of FM PT47 underlined that FM PT47 endorsed the approach in which the long term protection objectives for radiocommunication services may not be met in case of LAES systems used in emergency and disaster situations close to those radio stations. The technical requirements proposed for LAES systems should however prevent harmful interference to radiocommunication services in any situation whereas specific coordination and authorisation measures are necessary in order to ensure that the long term protection requirements of radiocommunication services are met in case of LAES operation in permanent training sites.
Russia expressed concerns about the maximum power spectral density level of -41.3 dBm/MHz, and even higher in the band 3.4 – 4.2 GHz (-21.3 dBm/MHz), and indicated that they intend to further examine the studies and comment during the public consultation.
France expressed concerns about the protection of radar altimeters operating in the band 4.2 – 4.4 GHz under the Aeronautical Radio Navigation Service given the study presented in ECC Report 64 and calling for a limit of -47 dBm/MHz to address single interference scenarios. The concern is about finding ways to impose a -47 dBm/MHz limit for elevation angles greater than 30° applicable also for outdoor use in emergency situations. France indicated that they intend to comment on this issue during the public consultation.
WG FM adopted for public consultation draft ECC Recommendation on LAES (see Annex 21).
5.7 FM PT 48 (Broadband DA2GC)
The Chairman of FM PT 48, Mr. Thomas Weilacher (D), introduced the Progress Report for the second meeting of the project team (FM(11)090).
FM PT 48 had discussed the evaluation and prioritisation of candidate bands.
