Communication apparatus

A communication apparatus that performs wireless communication obtains information of a channel with a possibility of interference in wireless communication that is output based on position information of the communication apparatus, position information of a source of a radio wave which has a possibility of interference in the wireless communication, and time information, and selects a channel to be used in the wireless communication. Whether a channel corresponding to the obtained channel information is the currently selected channel is determined, and the currently selected channel is changed to a channel other than the channel corresponding to the obtained channel information if the channel corresponding to the obtained channel information is the same channel as the currently selected channel. If communication is being performed, it is determined after the communication whether the channel corresponding to the obtained channel information is the same channel as the currently selected channel.

Method and device for selecting a channel based on interference and position information

A receiving unit () receives a message transmitted from any one of the users that are talk targets. The interpreter () attempts to interpret, as an answer to a question, the message received by the receiving unit (). A collector () collects, upon success of the attempt made by the interpreter (), the interpreted answer as the answer from the user who sends the message. When a predetermined requirement is satisfied in a state where a yet-to-respond user whose answer is not yet collected by the collector () is present, an inquiry transmitter () transmits an inquiry about the question to at least the yet-to-respond user among the users. A result transmitter (), after the answers are collected from all of the users, transmits to the users a message indicating a result obtained by tallying the answers.
