Abstract: A receiver includes a first detector that detects a Received Signal Strength Indicator of a desiring signal wave transmitted from a transmitter, a second detector that detects a power of interfering wave generated by an external device, a transmission rate selection processor that selects a transmission rate, which is used to transmit a signal from the transmitter to the receiver, from among a plurality of transmission rates based on the detected Received Signal Strength Indicator of the desiring signal wave and a detected power of the interfering wave, when the second detector detects generation of the interfering wave, and a transmission rate notificator that notifies the transmitter of the transmission rate selected by the transmission rate selection processor.

Abstract: A wireless communication device has an aim of specifying, when transmitting data to another communication device, an antenna among antennas that can transmit data at a low transmission power. The wireless communication device switches between a first antenna and a second antenna upon transmission of a request signal to the other communication device, and increases or decreases transmission power for transmitting the request signal when switching between the first antenna and the second antenna.
