1. A wireless communication apparatus for transmitting/receiving a signal within a frequency band for which radar wave detection is required, the wireless communication apparatus comprising:

  • communication means for transmitting/receiving wireless data at a plurality of available carrier frequencies;

    radar wave detection means for monitoring a radar wave at the currently used carrier frequency; and

    communication control means for controlling the communication operation of said communication means either in an interference avoidance operation mode for detecting a radar wave and instructing various stations to change the employed carrier frequency in accordance with a radar wave detection or in a normal operation mode for performing a communication operation while changing the employed carrier frequency in compliance with a remote station'"'"'s instruction for a change in the employed carrier frequency, wherein said communication control means retains a sequence table, which describes an operating sequence that is defined by communication stations operating in the same communication range, to determine the order in which the communication stations operate in the interference avoidance operation mode.
