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 SourceUSAustraliaRussiaJapanChina Huawei, Ericsson, Nokia GSMAIndia Date Total: MHz MHz MHz MHz (by 2015) MHz (by 2020) MHz (Low user density) MHz (High user density) MHz Additional: 275 MHz300 MHz385 MHz 300 MHz (by 2017) 200 MHz ( by 2020)

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 – MHz – MHz – MHz – MHz – MHz – MHz – MHz – MHz – MHz – MHz En-route Radar (1 300 – MHz) Airport /Windfarm/Met Radar 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 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 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 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
