F E D E R A L A V I A T I O N A D M I N I S T R A T I O N A I R T R A F F I C O R G A N I Z A T I O N Agenda Item 1.6 World Radiocommunication Conference 2007Agenda Item 1.6 –To consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC ‑ 03) and … Studies assigned to ITU-R Working Party 8B Latest WP8B (September 4-13, 2006) meeting has resulted in text for the Conference Preparatory Manual (CPM) on AI1.6
F E D E R A L A V I A T I O N A D M I N I S T R A T I O N A I R T R A F F I C O R G A N I Z A T I O N Results of studies Two distinct categories of AM(R)S spectrum are required. –The first – for surface applications at airports – is distinguished by a high data throughput, however only moderate transmission distances and it is expected that a single resource can be shared at multiple geographic locations. –The second category, like the current Very High Frequency (VHF) AM(R)S, will require longer propagation distances (e.g. out to radio line-of-sight), moderate bandwidth, and a number of distinct channels to allow for sector-to-sector assignments. Initial estimates of potential spectrum requirements have been determined taking into account evolving aeronautical applications, and integration of a new system on an aircraft. The estimates are: –approximately 60-100 MHz for surface applications at airports, and –approximately 60 MHz for radio line-of-sight applications.
F E D E R A L A V I A T I O N A D M I N I S T R A T I O N A I R T R A F F I C O R G A N I Z A T I O N Bands proposed portions of the band 108-117.975 MHz –112 or 116 to 117.975 MHz all or portions of the band 960-1164 MHz –960 to 1024 or 1164 MHz all or portions of bands in the 5 000-5 150 MHz frequency. –5000-5010 MHz, 5010-5030 MHz and/or 5030 or 5091 to 5150 MHz No single band will accommodate all of the identified AM(R)S requirements –allocations will be required for multiple bands in order to fully satisfy the Agenda Item.
F E D E R A L A V I A T I O N A D M I N I S T R A T I O N A I R T R A F F I C O R G A N I Z A T I O N Aeronautical Security System Consistent with considerings d), f) and g) of Resolution 414 (WRC-03), the 5 091 ‑ 5 150 MHz band is also being considered to support new aviation security requirements. Aeronautical security transmissions ensure confidential and secure communications between aircraft and ground, principally during unlawful disruption, hijacking or subversion of flight. –Security requirements could include video and voice monitoring and download of security data. Requires a complementary aeronautical mobile service (AMS) allocation to that band.
F E D E R A L A V I A T I O N A D M I N I S T R A T I O N A I R T R A F F I C O R G A N I Z A T I O N Status WP8B agreed on CPM text addressing all of the bands Disagreements on band edges addressed as separate methods Aeronautical Security system is its own method Seems to be general agreement on getting allocations in XX-117.975 MHz; 960-YY MHz and ZZ-5150 MHz. 5000-5010 MHz and 5010-5030 MHz have less agreement due to potential impact on proposed radionavigation satellite service (RNSS) for those bands.
F E D E R A L A V I A T I O N A D M I N I S T R A T I O N A I R T R A F F I C O R G A N I Z A T I O N Next Steps Aviation needs to continue to work within their administrations to support AI1.6 bands Use ACP WGF to “spread the word” Need special emphasis on 5000-5010 and 5010- 5030 MHz bands –Wider distribution of study results – indicates feasibility of compatibility –Emphasis that non-compatibility cannot be shown since neither system has been fully defined.
