1. A method of adjusting transmission power of a transmitter during a communication with a receiver, said transmitter transmitting a burst signal to said receiver, said method comprising the steps of:

  • broadcasting an upper threshold signal strength value, a lower threshold signal strength value, and a nominal signal quality value to the receiver;

    measuring a received signal strength of said burst signal received by said receiver;

    developing a signal quality value for said burst signal received by said receiver;

    setting a power control bit to a first value if said received signal strength is lower than said lower threshold signal strength value;

    setting said power control bit to a second value if said received signal strength is higher than said upper threshold signal strength value;

    setting said power control bit to the first value if said signal quality value is lower than said nominal signal quality value and said received strength signal is both higher than said lower threshold signal strength value and lower than said upper threshold signal strength value; and

    ,setting said power control bit to the second value if said signal quality value is higher than said nominal signal quality value and said received strength signal is both higher than said lower threshold signal strength value and lower than said upper threshold signal strength value.
