<p><P>PROBLEM TO BE SOLVED: To suppress the consumption of a battery of radio communication equipment by decreasing a carrier sense frequency and so on and to change a carrier frequency to avoid jamming. <P>SOLUTION: The radio communication device equipped with a carrier frequency changing means having a carrier sense frequency register 13a which stores the carrier sense frequency, a threshold OVER counter 13b which measures and stores the frequency at which a received signal level exceeds a specified threshold, and a local-station-address matching counter 14 which judges whether received data are addressed to its station and stores the number of signals addressed to its station reads out the carrier sense frequency, the frequency at which the signal level exceeds the threshold, and the number of the signals addressed to its station and judges whether the carrier frequency needs to be changed from the read-out frequencies and number. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
