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) 2

UK PMR/PAMR Market • 60,000 PMR Assignments • 750,000 PMR Mobiles • 2317 PAMR Assignments • 52,510 PAMR Mobiles • +1,000,000 PMR 446 Mobiles • Others • Public Safety Communications • GSM-R • London Underground • Dolphin (40,000 Subscribers) • PMR Contributes £1 to 2 Billion to UK GDP • PAMR Contributes approximately £550Million UK GDP 6
Overview 7
Wide Area PMR Data Licences • 20000 wide area assignments • In 2002, 2.5% use data • Data usage is growing steadily 9
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 12
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 13
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) 14
