| Abstract: |
The present invention is directed to a communication system which can be utilized to complement an existing cable television system in which a central office transmits signals along a coaxial cable to a user unit through a tap. The communication system features a central transmitting/receiving unit for wirelessly transmitting first signals generated at the central office and for receiving second signals. A first response unit which may be connected to the tap will receive the first signals wirelessly transmitted from the central transmitting/receiving unit, and will generate and wirelessly transmit the second signals to be received by the central transmitting/receiving unit. A further second response unit may be connected to the user unit, and the second response unit may generate a third signal to be wirelessly received by the first response. The third signal may be used to control the tap connected to the first response unit. Further, a relay unit may be provided to facilitate transmission between the first and second response units in the central transmitting/receiving unit.
