Abstract
Abstract A method and a communications system in which a request for data transmitted by an airborne transmitter over a low-bandwidth air-to-ground communication system uplink and received by a ground-based receiver. The requested data is then transmitted over a high-bandwidth communication system downlink, such as a DBS satellite system downlink, preferably using an MPEG-2 compression technique, and received by an airborne receiver located on the same aircraft as the airborne transmitter. The received request for data is transmitted to a data network that contains the requested data, such as the Internet or a private data network, using circuit-switched techniques. According to the invention, the requested data includes one of video information, audio information and textual information.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
135 words
A method for air to ground communication, comprising the steps of: (a) transmitting a request for a data session from an air borne terminal via an airborne transceiver and first antenna using a low bandwidth downlink to a ground based gateway linked to a server connected to a data network; (b) transmitting a service initiation acknowledgement from the server to the airborne terminal via the ground based gateway, the low bandwidth downlink, the airborne transceiver and first antenna; (c) transmitting a data request from the airborne terminal to the data network via the airborne transceiver and first antenna, low bandwidth down link, the ground based gateway and the server; and (d) transmitting the requested data from the data network to the airborne terminal via a high bandwidth satellite uplink, an airborne receiver and second antenna.
Claim 2
Independent Claim
