Abstract
A data rate is to be determined depending on circumstances. A control unit () transmits, at a predetermined frequency, a request signal by which to supply information on a data rate to a targeted radio apparatus compatible with a variable data rate. The control unit () receives rate information from the targeted radio apparatus. The control unit () sets a data rate used in the case of transmitting data, based on the information on a data rate contained in the rate information. The control unit () identifies the reliability level of the data rate contained in the rate information. And when the reliability level is low, the control unit () lowers the frequency at which the rate request signal is transmitted.
