1. A wireless communication system in which a plurality of cells are located substantially adjacent one another, the wireless communication system operating over a specified frequency range to provide signals in a forward direction from a central base transceiver station towards subscriber units located in the cells, the system comprising:

  • a hub interface converter, for accepting radio frequency signals from at least one base station, the radio frequency signals comprising at least one base station traffic signal modulated onto a radio frequency carrier (RF), for upconverting such radio frequency signals to an optical frequency carrier signal, and for coupling such optical frequency carrier signal as an optical forward transport signal onto an optical fiber;

    an optical fiber for distributing the optical forward transport signal;

    a plurality of optical splitters connected to the optic fiber; and

    a plurality of cable integrators, each receiving the optical transport signal from one of the splitters, each cable integrator associated with a respective one of the cells, each cable integrator further including an optical demodulator to translate the optical forward transport signal to corresponding transmit radio frequency signals such that the transmit radio frequency signals in at least two cells have the same radio frequency carrier.
