The Chairman of WG FM expressed that this information does not impact the proposal for amending Decision ECC/ECC/(06)04. When these new studies will be completed by WG SE, WG FM should consider if the generic UWB regulation needs to be further amended. This was endorsed by WG FM.


Russia expressed concerns about the maximum power 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 Decision ECC/ECC/(06)04 (see Annex 18).

5.6.3.Location tracking applications type 2 (LT2)


The Chairman of FM PT47 presented the proposals from FM PT47 concerning UWB LT2 systems (see doc. FM(11)079 section 1.1.2).

ECC Report 167 on practical implementation of registration/coordination mechanism for UWB LT2 systems:


The ECO introduced the comments received during public consultation on draft ECC Report 167 on practical implementation of registration/coordination mechanism for LT2 systems (see doc. FM(11)078). He underlined that these comments have been considered by FM PT47.


Following a remark by the Chairman of WG FM, the meeting endorsed the conclusion from FM PT47 that the comments received by UKBroadband should in general not change the draft ECC Report 167.


WG FM adopted for publication ECC Report 167 on practical implementation of registration/coordination mechanism for LT2 systems (see Annex 19).

ECC Recommendation on UWB LT2 systems:


Denmark asked for clarification on the operating frequency band for LT2 systems, whether it is the band 3.1 – 4.8 GHz or 3.4 – 4.8 GHz.


The PT FM47 Chairman expressed that the new compatibility studies performed by SE24 and presented in draft ECC Report 170 considered only the frequency band 3.4 – 4.8 GHz. However, based on a request from one manufacturer in FM PT47 to enable possible enhanced operation, it was agreed to offer the possibility to operate in the band 3.1 – 3.4 GHz with -41.3 dBm/MHz maximum mean e.i.r.p. spectral density subject to the implementation of Detect And Avoid (DAA) mitigation technique. Technical parameters for DAA in band 3.1 – 3.4 GHz are defined in ECC/DEC/(06)04 consistently with ECC Report 120. The operating frequency band for LT2 systems is therefore the band 3.1 – 4.8 GHz, i.e. where a maximum mean e.i.r.p. spectral density of -41.3 dBm/MHz can be allowed subject to additional mitigation requirements.


France underlined that the text in section 2 of the Annex developed by FM PT47 stipulates that further measures are required for operation within the specified protection distances and provides a reference to ECC Report 167. ECC Report 167 however does not provide mandatory requirements and should be understood as a guidance document intended for those administrations who wish to allow LT2 with some kind of registration mechanism. France therefore proposed to complete this sentence by adding “including possible coordination by the national administration”. This modification was approved by the meeting.
