1. An RF wireless communication system operating in the presence of a periodic noise environment, comprising first and second wireless devices, each such device including:

  • i) a source of power;

    ii) a transceiver coupled to the power source, for transmitting and receiving wireless information;

    iii) a controller/CPU for controlling the operation of the transceiver;

    iv) means in the transceiver for receiving radiated RF periodic noise and for detecting and mapping the radiated RF periodic noise, including means for mapping storing and generating a sync signal which represents the envelope of the periodic noise source and its quiescent period signature, and means for continuing to generate the sync signal even when the radiated periodic noise is no longer detectable, and v) means responsive to the mapped radiated RF periodic noise for controlling the operation of the transceiver to communicate with the other wireless device during the quiescent periods of the radiated RF periodic noise, including means for enabling the transmitter to transmit when it predicts the periodic noise is in the quiescent state, thereby making the transmission process efficient.
