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.
AIR TRAFFIC ORGANIZATION
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

C-Band Research Description – FY09
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
AeroMACS NASA-CLE CNS Test Bed
• ITT’s AeroMACS prototype implements features required to
support mobile and stationary wideband communications for
safety and regularity of flight services in an operational airport
environment
• Full prototype network has been installed, including user
verification and security with Authentication, Authorization, and
Accounting (AAA) server function
• AeroMACS hardware and network installation completed in
October 2009 with two multi-sector base stations providing wide
area coverage and redundancy (one on Glenn property, one on
CLE) and eight subscriber stations (two on Glenn, six on CLE)
• AeroMACS operational capability established in March 2010

AeroMACS FY10 Evaluations
• 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
Funded Research Activities in FY11
• Evaluate selected ATC mobile applications on the aeronautical
mobile airport communications system (AeroMACS)
• Investigate and resolve remaining issues affecting the final
AeroMACS profile inputs to the MOPS process
Evaluate and recommend mobile Source Station (SS) MIMO antenna
configurations for mobile SSs
Optimize AeroMACS system-level performance (QoS, data throughput,
latency, error rate) within ITU limitations on radiated power
Resolve channel BW and center frequency spacing plans to satisfy US
and European objectives while preserving Spectrum Office flexibility
and compatibility with WiMAX Forum practices
Validate that the proposed AeroMACS complies with interference
requirements for the US proposed allocation at World
Radiocommunications Conference in 2012.

Approach for Technical Parameter Profile
•
•
•
System profile define AeroMACS
operation in the unique airport surface
environment
Profile based on IEEE 802.16-2009

Leverages commercial mobile
Worldwide Interoperability for
Microwave Access (WiMAX) for
profiles, hardware, software, and
network architecture
•
Testing, analyses, and demos will
validate that application needs are met
•
RTCA SC-223 is developing FAA
