2 What is today about? Making the best use of Spectrum to support PMR Data Services To review the Licensing Arrangements of PMR Data Services To Review the Policy surrounding PMR Data Services (IR2008) To look to the future of PMR Data Services regarding Technology (higher bit rates/DMR)

12 What is the RA’s view? Using current Analogue techniques - Voice doesn’t share with Data Virtual exclusive channels (IR2008), the way forward with analogue PMR using data to ‘share’ channels politely We support the new Low cost DMR standard being developed within ETSI
13
13 What is the RA’s view? Spectrum - UK desires to meet ECA Table –projects underway to align UHF1 and UHF2 –difficult to align congested bands –extensive existing narrow band usage Market –large base of existing narrow band users –some sectors growing, others declining –overall decline but growth in on site at UHF, wide area data at VHF
14
14 What is the RA’s view? Technology –the future is digital - need to configure spectrum to allow introduction of current generation digital equipment, hence alignment –PMR446 a success, would like to introduce a digital equivalent –No current digital equipment manufactured in VHF, therefore a low priority for alignment (but majority of LM spectrum in VHF)
