  1. WRCAgenda Item 1.1 to consider additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications, in accordance with Resolution 233 (WRC-12) Presented by John Mettrop Nairobi 3 – 4 September 2013

  2. Requirements • Meet expected growth that is driven to a large extent by audiovisual content • Available in a timely manner • Harmonized worldwide • Preferably adjacent to existing allocations • Consistent with existing mobile standards • Mobile telephony • WiFi

  3. Estimated Spectral Needs

  4. Expected Benefits • Multimedia applications • Mobile telemedicine • Teleworking • Distance learning • Reduce digital divide between urban & rural areas • Improved RLAN performance/capacity • Continued growth of the mobile market

  5. Frequency Ranges Identified for Study 470 – 674/698 MHz 1 300 – 1 400 MHz 1 427 – 1 527 MHz 1 695 – 1 700 MHz 2 025 – 2 110 MHz 2 200 – 2 290 MHz 2 700 – 3 100 MHz 3 300 – 4 200 MHz 4 400 – 5 000 MHz 5 350 – 5 470 MHz 5 725 – 6 425 MHz En-route Radar (1 300 – 1 350 MHz) Airport /Windfarm/Met Radar Radio Altimeters (Adjacent Band) Radio Altimeters (Adjacent Band) Weather Radar (Airborne/Land based)

  6. L-Band Radar • System • En-route • High power • Sensitive receivers • Located • Remote areas • Airports • Ranges up to 240 nmi • Studies to date • Russian • Indicates significant incompatibility towards radar • Should be eliminated from list of candidate frequency bands

  7. S-Band Radar • System • High power • Sensitive receivers • Located • Remote areas • Windfarms • Airports • Ranges up to 40-60 nmi • Studies to date • Russian • Significant incompatibility towards radar • Should be eliminated from list of candidate frequency bands • UK • Significant incompatibility in both directions • Possibility of band segmentation • Modify current radar • Changes to mobile equipment specifications • Need for a guard band

  8. C-Band Radar • System • Use • Airborne weather radar • Land based weather radar • High power • Sensitive receivers • Ranges 80 -120 nmi • Studies to date • USA • Possibilities subject to power restriction

  9. Radio Altimeter • System • Located on aircraft • Used in all phases of flight • Integral part of the automated landing system • Sensitive receivers • Ranges up to 6,000ft vertically • Studies to date • None • Planned UK Contribution

  10. Where is the Work Being Done • Globally • Joint Task Force 4-5-6-7 • Working Party 5D • Regionally • Africa - ATU • Americas – CITEL • Arab Group – ASMG • Asia Pacific – APT • Europe – CPG PT-D • Russian Commonwealth – RCC • ICAO • ACP WG-F
