Communicating in the presence of periodic noise

Abstract

A wireless communication system operating in the presence of the periodic noise signals such as from a microwave oven, the communication system, including at least two wireless communication stations with each station including a transceiver, each such transceiver. Each transceiver includes a detector for detecting periodic noise signals and producing a first signal indicating the presence of noise signal's quiescent period and second signals indicating the end of quiescent periods of such periodic noise signal. A controller responsive to the first and second noise signals controls the transceiver to provide effective communication with an other transceiver which minimizes the noise effect of the periodic noise signal. The transceiver transmits information concerning the detected quiescent period for use by the other transceiver to determine when to transmit during such quiescent period.

1 . A wireless communication system operating in the presence of periodic noise signals, the communication system comprising: 
 a first transceiver comprising a detector detecting a quiescent period in the periodic noise signals and the first transceiver transmitting a quiescent period signal; and    a second transceiver wirelessly receiving the quiescent period signal and transmitting an information signal responsive to the quiescent period signal.    
   
   
       2 . A wireless communication method for operating in the presence of periodic noise signals, comprising: 
 detecting a quiescent period in the periodic noise signals at a first location and wirelessly transmitting a quiescent period signal responsive to the detection; and    receiving the quiescent period signal wirelessly at a second location and wirelessly transmitting an information signal responsive to the received quiescent period signal.
