an optimized integrated high capacity digital satellite trunking network , otherwise known as the multipurpose wideband communications system and method to link multiple earth stations in the same or different satellite antenna transponder footprints using uplink frequency to select the downlink footprint . the configuration of the network eliminates the need to reconfigure the transponder based on the desired downlink footprint . the invention integrates wideband receivers and hybrid signal combiners on the satellite along with an appropriate uplink and downlink frequency plan to provide the ability to reconfigure connectivity between uplink and downlink footprints based on uplink frequency selection . certain configurations allow single hop connectivity between all transponder antenna footprints for all users within those footprints of the geostationary satellite . the system uses the full power and bandwidth of the constituent communications satellites for all services without dividing the power or bandwidth among multiple networks .
