COMMUNICATION DEVICE, COMMUNICATION METHOD, TERMINAL DEVICE AND COMMUNICATION SYSTEM

摘要

Provided is a communication apparatus which allows multi-rate control causing less waste of communication band as compared to conventional, the communication apparatus (100) according to the present invention includes: the wireless communication unit (120) for performing wireless communication with the terminal apparatus; a transfer rate setting unit (102) for setting a transfer rate; a beacon generation unit (106) for generating a beacon which is a first control signal; and a control unit (110) for causing the wireless communication unit (120) to wirelessly transmit, for every predetermined period, the beacon, and, to cause the wireless communication unit (120) to wirelessly transmit the beacon, the control unit (110) causes the transfer rate setting unit (102) to set a transfer rate different from the transfer rate previously used for the wireless transmission of the beacon, and causes the wireless communication unit (120) to transmit the beacon to the terminal apparatus.
