Background

  • Future Communications Study (AP-17), ICAO Aeronautical Communications Panel, Recommendation #1:
    • Develop a new system based on the IEEE 802.16e 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 system
    • Test bed infrastructure to enable validation of aviation profile

c band datalink recommendations
C-band Datalink Recommendations

Develop airport surface system based on IEEE 802.16e 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.

2007 world radiocommunications conference decision
2007 World Radiocommunications Conference Decision

The WRC-07 approved adding an AM(R)S allocation for 5091-5150 MHz to the International Table of Frequency Allocations

Removed prior limitation in so-called MLS Extension Band for “support of navigation/surveillance functions”

AM(R)S designation for safety and regularity of flight applications

No interference allowed with other occupants in the band: non-GEO satellite feeder links and aeronautical telemetry

Protected allocation enables ICAO to develop international standards for airport mobile (i.e., wheels in contact) surface wireless communications networks that include fixed assets

Ideal 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 5000-5030 MHz band

Develop ConUse, requirements, and architecture for the C-Band airport surface wireless communications system

Conduct supporting system analyses (e.g. high-level safety, interference, wireless security, risk assessment) 

Develop detailed system designs based on IEEE 802.16 standards

Establish an operational capability in NextGen CNS Test Bed to characterize the performance and conduct services demos/trials

Develop test and demo plans and execute those plans to establish baseline performance as point of departure for proposed aeronautical services modifications

Develop initial recommendations for joint RTCA/EUROCAE standards activities and provide support to new RTCA SC, and propose methods to validate standards in follow-on tasks

  • Measure data throughput and packet integrity for the following conditions:
    • 5 and 10 MHz channel bandwidths
    • Stationary and mobile subscriber stations at speeds of at least 40 knots
    • Line-Of-Sight (LOS) and Non-LOS (N-LOS) propagation links
    • Presence of adjacent channel activity
  • Mobility tests with hand-off transition between base station coverage sectors and between base stations
  • Determine minimum transmit power required to maintain a minimum level of link performance:
    • Single subscriber station antenna
    • MIMO antenna diversity
  • Characterize link performance when transferring sensor data from MLAT sensors in test bed
    • Mixture of data traffic streams
    • Traffic priority setting with Quality of Service (QoS) settings
