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.
