Further discussion within FM47 on this Work Item is pending the outcome of SE24 studies on LAES.

Location tracking applications type 2 (LT2) operating in the frequency bands 3.4 – 4.8 GHz and 6 – 8.5 GHz for person and object tracking and industrial applications

SE24 has initiated the compatibility studies. FM47 is developing a report on practical implementation of registration/coordination mechanism for UWB systems.

 

The convenor of the FM47 correspondence group on LT2, Miguel Capela (Portugal) introduced the working document developed by the correspondence group. The prime aim of this report is to describe and evaluate possible solutions on practical implementation of registration/coordination mechanisms for UWB LT2 systems. It also considers how such approaches could be applied to other UWB devices operated at fixed location which exceed the power levels set out in existing UWB regulations. The draft report distinguishes “Coordination/Registration mechanism” allowing coordination and site engineering in any area or only in specific well defined areas. Work in SE24 and FM47 will progress in parallel, noting that the necessity for possible “Coordination/Registration mechanism” in case of UWB LT2 systems should depend upon the outcome of compatibility studies.

 

Finally, given the connection here with work that WGRA is already carrying out - investigations in relation with cognitive radios for example - and that it is possible that FM47 would benefit from WGRA’s experience in this area - FM47 agreed to develop a draft Liaison statement from WGFM to WGRA on authorisation mechanism for UWB systems operated at fixed location which are not compliant with the generic UWB regulation.

 

Location tracking and sensor applications for automotive and transportation environments (LTA) operating in the frequency bands from 3.1 – 4.8 GHz and 6 – 8.5 GHz

SE24 is investigating alternative LDC mitigation technique (“LDC3”) for the automotive environment. ETSI no longer considers frequency band 3.1 – 3.4 GHz for automotive UWB applications.  It has been proposed to remove the “long term” duty cycle restriction (maximum 0.5%/hour) for UWB LDC operation in the frequency bands 3.4 - 4.8 GHz and 6 – 8.5 GHz. Further discussion within FM47 on this Work Item is pending the outcome of SE24 studies on LTA.

 

Airborne UWB applications operating in the frequency bands from 3.1 GHz to 4.8 GHz and 6 GHz to 8.5 GHz

SE24 is investigating the compatibility of UWB airborne with radio systems outside the aircraft. Further discussion within FM47 on this Work Item is pending the outcome of SE24 studies on Airborne UWB.

 

Generic UWB regulation

 FM47 had a general discussion relating to the review of the generic UWB regulation. The objective could be a submission of draft amended Decisions ECC/DEC/(06)04 and/or ECC/DEC/(06)12 to WGFM for consideration at its meeting in September 2010 in view of possible adoption for public consultation by ECC at its meeting in November 2010.

Comparable technical specifications to those given in these ECC Decisions are given in EC Decision 2007/131/EC (amended by Decision 2009/343/EC). It should be noted that the change foreseen at previous FM47 meeting aims to provide further clarification on the European regulatory framework but would not contradict the existing EC Decision on UWB. As part of this review exercise, some consideration could also be given to the RIS (RIG2) template which had been used by TG3 at its final meeting for describing the generic UWB regulation (see Annex 5 to Doc. TG3#24_10R0) in view of supporting WGRA investigations.

Overview of existing UWB regulations and ongoing work on UWB

FM47 discussed document FM47(10)005 submitted by FM47 Chairman which aims to recall the existing UWB regulations in Europe and to clarify the scope of ongoing discussions within SE24 and FM47 relating to UWB (except SRR).
