Abstract

An RF wireless communication system operating in the presence of a periodic noise environment, includes first and second wireless devices, each such device having: a source of power; a transceiver coupled to the power source, for transmitting and receiving wireless information; a controller/CPU for controlling the operation of the transceiver; means for detecting and mapping the presence of the RF radiated periodic noise; and means responsive to the mapped 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.
