Patent ID: 8094640

Claim:
A full duplex wideband modem, comprising: a wideband transmitter for transmitting high data rate communications; a wideband receiver for receiving high data rate communications; a band select switch coupled to the transmitter and receiver for selecting one of a high band or a low band in accordance with a first unused frequency associated with transmitted high data rate communications and selecting a second unused frequency in the unselected high band or low band associated with received high data rate communications, wherein the band select switch passes both the transmitted high data rate communications and the received high data rate communications, a duplexer for isolating the wideband receiver from the wideband transmitter, wherein the band select switch reverses the connection of the wideband transmitter and the wideband receiver to a high-pass and a low-pass port of the duplexer, wherein the duplexer attenuates the transmitted high data rate communications, and wherein the full duplex wideband modem communicates with a second full duplex wideband modem when the band select switch of each full duplex wideband modem is set in opposite positions.
