发明名称 Terminal device
摘要 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.

主权项 1. A terminal device comprising: a positioning portion that acquires a location of an object; a setting portion that sets a waiting time period in a case where the location acquired by the positioning portion meets a predetermined condition; a carrier sense portion that performs carrier sensing for the waiting time period set by the setting portion; and an output portion that outputs a packet signal based on a result of the carrier sensing performed by the carrier sense portion, wherein a range of the waiting time period which the setting portion is able to set is narrower than a range of a waiting time period that another terminal device, which is able to perform carrier sensing to output a packet signal, is able to set.
