1. A wireless, backboneless communication system for transmitting and receiving radio frequency (RF) signals inside an enclosure having a high likelihood of multipath transmission and reception wherein the strength of said RF signals outside of said enclosure is limited by electromagnetic compatibility (EMC) and electromagnetic interference (EMI) standards, comprising:

  • a first electronic device located in said enclosure;

    a second electronic device located in said enclosure;

    a first transmitter/receiver connected to said first electronic device for transmitting spread spectrum signals based on first transmit data generated by said first electronic device and for receiving spread spectrum signals; and

    a second transmitter/receiver connected to said second electronic device for transmitting spread spectrum signals based on second transmit data generated by said second electronic device and for receiving spread spectrum signals, wherein said first and second transmitter/receivers operate between 100 to 900 MHz and said spread spectrum signals generated by said first and second transmitter/receivers are above a thermal noise threshold of said first and second transmitter/receivers and are below said EMC/EMI standards.
