Dual-band radio communications system for aeronautical data communications

摘要

The present invention uses a VDL Mode 4 RF network as the primary transmission path for data transmitted from aircraft to ground stations, and one or more separate non-VDL Mode 4 RF network(s) as the primary transmission path for data transmitted from ground stations to aircraft. The unique characteristics of each network provide for a cost-effective solution to the two-way aeronautical networking problem.
