1 Aeronautical Mobile Airport Communications System (AeroMACS) Status Briefing Presentation to WG-M/18 Montreal, CanadaPresented by: Brent Phillips; FAADate: July 18, 2011
2 BackgroundFuture Communications Study (AP-17), ICAO Aeronautical Communications Panel, Recommendation #1:Develop a new system based on the IEEE e standard operating in the C-band and supporting the airport surface environment.NextGen Implementation Plan (FY09, FY10 & FY11) to improve collaborative Air Traffic Management includes “New ATM Requirements: Future Communications”Concepts of use, preliminary requirements, and architecture for C-band airport surface wireless communication systemTest bed infrastructure to enable validation of aviation profile2
3 C-band Datalink Recommendations Develop airport surface system based on IEEE e standard [A1.1] Identify the portions of the IEEE standard best suited for airport surface wireless communications, identify and develop any missing functionality and propose an aviation specific standard to appropriate standardisation bodies; [A1.2] Evaluate and validate the performance of the aviation specific standard to support wireless mobile communications networks operating in the relevant airport surface environments through trials and test bed development; [A1.3] Propose a channelization methodology for allocation of safety and regularity of flight services in the band to accommodate a range of airport classes, configurations and operational requirements; [A0.4] Complete business analysis in relation to the FCI components and implementation from the perspective of the ground infrastructure and the airlines.A I R T R A F F I C O R G A N I Z A T I O Nato3
4 2007 World Radiocommunications Conference Decision The WRC-07 approved adding an AM(R)S allocation for MHz to the International Table of Frequency AllocationsRemoved prior limitation in so-called MLS Extension Band for “support of navigation/surveillance functions”AM(R)S designation for safety and regularity of flight applicationsNo interference allowed with other occupants in the band: non-GEO satellite feeder links and aeronautical telemetryProtected allocation enables ICAO to develop international standards for airport mobile (i.e., wheels in contact) surface wireless communications networks that include fixed assetsIdeal for airport surface wireless network with short range (~10 km or less sector coverage) and high data throughput (10s of Mb/s)The WRC-12 will consider adding an AM(R)S allocation in the MHz bandA I R T R A F F I C O R G A N I Z A T I O Nato4
