US Patent 8493906 Wireless aircraft gateway with auxiliary battery power

An aircraft gateway processing system for wirelessly transferring data between an aircraft and a ground server. The aircraft gateway processing system includes an aircraft gateway processor unit that includes a protocol data processing unit; and, a store and forward unit operably connected to the protocol data processing unit. An auxiliary battery power unit is operably connected to the aircraft gateway processor unit and configured to provide self-powered operation of the aircraft gateway processing system in the event of a loss of aircraft power during communications or initiation of communication when aircraft power is not available. At least one wireless communication interface is operably connected to the aircraft gateway processor unit for connection to the internet and ultimately to a ground server connected to the internet. At least one network data interface is operably connected to the aircraft gateway processor unit and operably connectable to another aircraft unit.
