Optimization of a full duplex wideband communications system
First Claim
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.

Abstract
Systems and methods are disclosed for a full duplex wideband communications system for a local (e.g. in-home) coaxial network. The system employs a Frequency-division duplex (FDD) scheme that allows identical wideband modems to communicate with each other. To achieve this, the wideband modems contain a duplexer and a switch that allows reversing the connection of the wideband transmitter and receiver to the duplexer. Each wideband modem includes a control modem that is used to control access to the wideband channels. A wideband transmitter, which may be included in a modem associated with a server set-top terminal (STT), transmits a video presentation to a wideband receiver, which may be included in a modem associated with a client STT.

8. A coaxial network for communicating a video presentation, the coaxial network comprising:
-
a plurality of wideband modems for transmitting and receiving video presentation in an optimized frequency to one or more of the plurality of wideband modems, a wideband modem comprising;
a transmitter for transmitting a video presentation;
a receiver for receiving a video presentation from a second wideband modem; and
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 optimized frequency associated with the transmitted video presentation, wherein prior to transmitting the video presentation, an optimization protocol is performed using control signals to determine the first optimized frequency. - View Dependent Claims (9, 10, 11, 12, 13, 14)
