Location Tracking Application for Emergency Services (LAES): FM PT47 approved a draft ECC Recommendation on LAES submitted to WG FM for adoption for public consultation (see doc. FM(11)079 Annex 1).

Location Tracking Applications type 2 (LT2):


FM PT47 approved a proposal on draft ECC Report 167 on practical implementation of registration/coordination mechanism for LT2 systems submitted to WG FM for adoption for publication (see doc. FM(11)079 Annex 3). FM PT47 also prepared a document where it provides its views on the comments from UK Broadband (see doc. FM(11)079 Annex 2).


FM PT47 approved a draft ECC Recommendation on LT2 submitted to WG FM for adoption for public consultation (see doc. FM(11)079 Annex 4).

Location tracking and sensor Applications for automotive and transportation environments (LTA): the outcome of these investigations is proposed to be handled by amending the generic UWB regulation. FM PT47 agreed to submit the draft amended Decision ECC/DEC/(06)04 (see doc. FM(11)079 Annex 5) to WG FM for adoption for public consultation.

Airborne UWB applications: the outcome of SE24 investigations should be presented at a later stage in a specific ECC Report on airborne UWB applications. No further discussion took place within FM PT47. Possible regulatory developments should be handled by SRD/MG.


After consideration of the various deliverables developed by FM PT47 (see sections 5.6.2, 5.6.3 and 5.6.4) WG FM agreed to close PT47 and thanked the FM PT47 Chairman and the project team for their achievements.


WG FM tasked SRD/MG to handle outstanding UWB matters, in particular to consider the outcome of the public consultation on regulatory deliverables adopted at this meeting.

5.6.2.Generic UWB regulation


The Chairman of FM PT47 presented the proposal from FM PT47 concerning the generic UWB regulation (see doc. FM(11)079 section 2). He underlined a number of issues discussed by FM PT47: definition of peak power, coexistence between UWB LDC and radars in the band 3.1 – 3.4 GHz, JRC measurements, “exterior limit”, services in band 4.2 – 4.8 GHz and protection of Radio Astronomy stations operating in the band 6650.0 – 6675.2 MHz. Concerning RAS at 6.7 GHz, he indicated that a compatibility study was submitted by CRAF to last meeting of SE24 calling for more stringent limits in the frequency range 6650.0 – 6675.2 MHz from LTA. He underlined however that the insertion of an “exterior limit” at -53.3 dBm/MHz should primarily improve the protection of radio services and radio astronomy compared with the current situation where it is only assumed that car screening will provide equivalent indoor/outdoor attenuation, but that the case of potential outdoor automotive applications should be carefully monitored.


The Liaison Statement from WG SE on UWB Low Duty Cycle mitigation (see doc. FM(11)098) was introduced. WG FM noted that WG SE has tasked SE24 to develop an ECC Report on Low Duty Cycle mitigation techniques implemented in UWB devices.
