Patent ID: 8310963

Claim:
A system comprising: a first unit; and a second unit communicatively coupled to the first unit; wherein the first unit is operable to receive a first original radio frequency signal in a first communication direction from an upstream device and the second unit is operable to receive a second original radio frequency signal in a second communication direction from a downstream device; wherein the first and second original radio frequency signals are originally transmitted on a radio frequency channel using time division duplexing; wherein the first unit communicates a control signal in the first communication direction to the second unit, the first unit generating the control signal based at least in part on detecting when the first original radio frequency signal is being received at the first unit; wherein the second unit uses the control signal to determine when to output a first reproduced radio frequency signal in accordance with the time division duplexing used to originally transmit the first and second original radio frequency signals on the radio frequency channel; and wherein the first reproduced radio frequency signal is derived from the content of the first original radio frequency signal and output from the second unit to the downstream device in the first communication direction.
