Mobile airborne high-speed broadband communications systems and methods
First Claim
1. A mobile platform high-speed broadband communications system for a mobile platform, the mobile platform high-speed broadband communications system comprising:
- a mobile communications terminal having a single first antenna;
a satellite in two-way communication with the mobile communications terminal through the first antenna; and
a base station in two-way communication with the satellite, wherein a return link signal is transmitted from the first antenna of the mobile communications terminal to the satellite on a first frequency;
the return link signal is retransmitted from the communications satellite to the base station on a second frequency;
a forward link signal is transmitted from the base station to the satellite on the first frequency;
the forward link signal is retransmitted from the satellite to the first antenna of the mobile communications terminal on the second frequency; and
the forward link signal is received by the first antenna.

Abstract
Improved high-speed, broadband data communication between a mobile terminal, including aircraft in flight, and secure, private remote networks, can be implemented by using the bandwidth of a single transponder on a satellite. The improved high-speed data communications system uses a single frequency to transmit the broadband data from the mobile terminal to the satellite and the same frequency to transmit the broadband data from the remote network to the satellite. Likewise, the improved high-speed data communications system uses a corresponding frequency on the same satellite transponder to transmit the high-speed, broadband data from the satellite to the mobile terminal and to transmit the high-speed, broadband data from the satellite to the remote network.
