Abstract
A wireless communication apparatus and transmission power control method are disclosed, which can sustain communication with all microphone handsets while avoiding an increase in radio interference to another radio communication system as much as possible when radio communication is performed with a plurality of microphone handsets. In the wireless communication apparatus, a level measurement section measures an RSSI level of a call signal each time the base unit receives a call signal from each microphone handset; and a transmission power control section controls an amplification section so that a transmission power value is determined at a predetermined timing using a minimum value of the RSSI levels of the respective microphone handsets, and that a control signal is transmitted to the microphone handsets with the determined transmission power value.
