Abstract:
1. A system for optimal transmission of high data rate signals among a plurality of full duplex wideband modems, the system comprising: a first wideband modem for transmitting high data rate signals in a first optimized frequency, wherein prior to transmitting the high data rate signals, an optimization protocol is performed using control signals, and for receiving high data rate signals in a second optimized frequency; and a second wideband modem for receiving the high data rate signals in the first optimized frequency, wherein each wideband modem comprises: a transmitter for transmitting high data rate signals; a receiver for receiving transmitted high data rate signals; a duplexer for combining the first optimized frequency and the second optimized frequency; a band select switch coupled on one end to the transmitter and the receiver for selecting one of a high band or a low band in accordance with the first optimized frequency, and coupled on another end to the duplexer, wherein if the first optimized frequency is associated with one of the high band or the low band, received high data rate signals in a second optimized frequency is associated with the other band; a control transmitter, that transmits on a third frequency, for sending control information to the second wideband modem, wherein the third frequency is outside a frequency band of the high and the low bands; a control receiver, that receives on the third frequency, for receiving control information indicating the optimized frequencies; and a diplexer coupled to (1) the duplexer and (2) the control transmitter and the control receiver, wherein the diplexer combines the third frequency with previously combined first and second optimized frequencies.
