1. In a wireless communication system wherein an area is divided into cells and at least one of the cells includes at least a part of a building, with a basestation located in said at least one of the cells to provide wireless communication to subscriber units located in said at least part of a building, the communication carried out by using modulated radio frequency (RF) carrier signals having a carrier signal frequency in excess of five-hundred MegaHertz (500 MHz), an apparatus for distributing the modulated RF carrier signals within the building using existing power line wiring within the building, the apparatus comprising:

  • a basestation radio transceiver for generating multi-carrier RF carrier signals having a carrier signal frequency in excess of 500 MHz intended for transmission to the subscriber units, and for receiving modulated multi-carrier RF carrier signals originating at the subscriber units;

    a connector for connecting the modulated RF carrier signals provided by the basestation radio transceiver to the building power line wiring;

    a plurality of antennas placed at various locations distributed within the building for transmitting RF carrier signals to subscriber units located in the building and for receiving RF carrier signals therefrom; and

    a plurality of antenna couplers, each antenna coupler connecting a respective one of the antennas to the building power line wiring to permit the modulated RF carrier signals to pass between the basestation radio transceiver and the antenna over the building power line wiring.
