Patent abstract
An acquisition unit determines the location of an object. A setting unit sets a wait time if the determined location satisfies predetermined conditions. The range of wait time that the setting unit can set is narrower than the range of wait time that can be set by other kinds of terminal devices capable of broadcasting packet signals by means of carrier sensing. A carrier sense unit performs a carrier sense over the set wait time. A modulator-demodulator unit and RF unit broadcast a packet signal together with the results of the carrier sense.
