Abstract:
Particular embodiments may provide a transceiver in geosynchronous orbit. The transceiver may include a plurality of forward channel receivers. At least one of the forward channel receivers may receive (1) a forward channel laser communication beam transmitted from a ground station and (2) an E-band frequency having a bandwidth of 81-86 GHz. The transceiver may also include a plurality of forward channel transmitters having different frequencies. The forward channel transmitters may transmit user beams to endpoint devices, wherein the user beams are derived from the forward channel laser and MMW communication beams. The transceiver may also include a plurality of return channel receivers, wherein the return channel receivers receive user beams from the endpoint devices. The transceiver may also include at least one return channel transmitter, wherein the return channel transmitter transmits a return channel laser communication beam to a ground station.
