<P>PROBLEM TO BE SOLVED: To provide a system and method of transmitting sensor signals in a waveguide environment. <P>SOLUTION: A sensor assembly 110 is configured to wirelessly receive a sensor interrogation signal, determine an input power level of the sensor interrogation signal, and transmit a message including the determined power level. The system also includes a sensor controller 108 configured to transmit a sensor interrogation signal, determine an output power of the transmitted sensor interrogation signal at a plurality of frequencies, receive an indication of the received input power level of the sensor interrogation signal from the sensor assembly at the plurality of frequencies, compare the transmitted output power of the sensor interrogation signal to the received power indication, and select a transmit frequency for transmitting messages between the senor assembly 110 and the sensor controller 108 based on the comparison. <P>COPYRIGHT: (C)2013,JPO&INPIT |
