Abstract
A communication device transmits a plurality of measurement packets to another communication device while successively varying a transmitting interval. After the plurality of measurement packets have been transmitted, the communication device determines a location of a usable bandwidth in relation to a first bandwidth range that is a range within which bandwidths are measured. The communication device resets the first bandwidth range to a second bandwidth range that is a range within which the bandwidths are measured and in which at least one of an upper limit and a lower limit is different from the corresponding limit in the first bandwidth range in accordance with the determination. The communication device selects a bandwidth that will be used when the measurement packets are transmitted. The communication device transmits the measurement packets to the other communication device using the bandwidth that has been selected.
