ABSTRACT
On an international basis, the 5000-5250 megahertz (MHz) frequency band is allocated to the aeronautical radionavigation service (ARNS). The 5030-5091 MHz portion is in use for microwave landing system (MLS) applications. The aviation community is exploring other applications in the 5091-5150 MHz band (referred to as C-band in this report).
One candidate aeronautical application in the C-band is in connection with supporting the Airport Network and Location Equipment (ANLE) utilization. ANLE is visualized as a high integrity, safety rated wireless network for the airport area, combined with a connected grid of multilateration sensors while simple transmitters are added to the surface—moving vehicles allowing for the development of a high-fidelity complete picture of the airport surface environment. Via a high-bandwidth internet-like connection, this airport wireless network would benefit the cockpit with situational awareness on the airport surface.
This report documents a preliminary investigation on the applicability of the wireless local area network (WLAN) and cellular network technologies, for use by the airport wireless system in C-band. The technology survey was conducted on IEEE 802.11a, IEEE 802.11b, cdma2000 and WCDMA. Also presented are a modeling effort to extend the Communications Adaptive Design and Radio Frequency Interference Environment (CADRE) toolset in C-band, and a preliminary analysis of the airport wireless system performance based on IEEE 802.11a and cdma2000 technologies. In addition, the report identifies technical issues and recommends potential areas of further analysis and testing.
