Abstract

2054198 9115068 PCTABS00007 A spread spectrum communications system uses a leaky coaxial cable for cost effective radio communication in enclosed areas. The system includes radio units (12) which communicate with a transceiver, the transceiver being coupled to the leaky coaxial cable (16). Full-duplex communication includes a first frequency band (F1) for transmitting spread spectrum signals from the transceiver to the radio units at power levels which are adjusted to take advantage of the losses associated with leaky coaxial cable, and a second frequency band (F2) for transmitting spread spectrum signals from the radio units to the transceiver at the more conventional spread spectrum power levels specified by the FCC. The present invention employs this split band configuration to accommodate communication over leaky coaxial cable without expensive and bulky filtering for isolation between the transmit and receive signals.
