<P>PROBLEM TO BE SOLVED: To enable measurement of radio wave environment of a radio channel when no communication is made on a network. <P>SOLUTION: A radio communication device periodically transmits a beacon signal to a plurality of radio terminal devices in a network by using either one of a plurality of radio channels. Thereafter, the radio communication device detects an electric field strength of the plurality of radio channels, chooses a specified period from a period during which radio communication with unspecified radio terminal devices in the network is prohibited in beacon intervals as a communication limitation period, and detects the electric field strength of the plurality of radio channels during the communication limitation period. <P>COPYRIGHT: (C)2012,JPO&INPIT |
