A communication apparatus comprising: a wireless communication unit configured to perform wireless communication with one or more terminal apparatuses; a transfer rate setting unit configured to set a transfer rate of the wireless communication performed by the wireless communication unit; a beacon generation unit configured to generate a beacon which is a first control signal to be transmitted by the wireless communication unit; and a control unit configured to cause the wireless communication unit to wirelessly transmit, for every predetermined period, the beacon generated by the beacon generation unit; wherein when causing the wireless communication unit to wirelessly transmit the beacon, the control unit is configured to cause the transfer rate setting unit to set the transfer rate different from a transfer rate previously used for wirelessly transmitting the beacon and cause the wireless communication unit to transmit the beacon to the one or more terminal apparatuses, whereby the beacon includes a first period value specifying a first period, a second period value specifying a second period, a first transfer rate value which specifies the transfer rate in association with the first period, and a second transfer rate value which specifies the transfer rate in association with the second period and different from the first transfer rate value and an identifier indicating whether the beacon is a first transfer rate beacon or a second transfer rate beacon, and the control unit is configured to cause the transfer rate setting unit to set the transfer rate to the first transfer rate value when causing the wireless communication unit to wirelessly transmit the r first transfer rate beacon in the first period, and cause the transfer rate setting unit to set the transfer rate to the second transfer rate value when causing the wireless communication unit to wirelessly transmit the second transfer rate beacon in the second period. a wireless communication unit configured to perform wireless communication with one or more terminal apparatuses; a transfer rate setting unit configured to set a transfer rate of the wireless communication performed by the wireless communication unit; a beacon generation unit configured to generate a beacon which is a first control signal to be transmitted by the wireless communication unit; and a control unit configured to cause the wireless communication unit to wirelessly transmit, for every predetermined period, the beacon generated by the beacon generation unit; wherein when causing the wireless communication unit to wirelessly transmit the beacon, the control unit is configured to cause the transfer rate setting unit to set the transfer rate different from a transfer rate previously used for wirelessly transmitting the beacon and cause the wireless communication unit to transmit the beacon to the one or more terminal apparatuses, whereby the beacon includes a first period value specifying a first period, a second period value specifying a second period, a first transfer rate value which specifies the transfer rate in association with the first period, and a second transfer rate value which specifies the transfer rate in association with the second period and different from the first transfer rate value and an identifier indicating whether the beacon is a first transfer rate beacon or a second transfer rate beacon, and the control unit is configured to cause the transfer rate setting unit to set the transfer rate to the first transfer rate value when causing the wireless communication unit to wirelessly transmit the r first transfer rate beacon in the first period, and cause the transfer rate setting unit to set the transfer rate to the second transfer rate value when causing the wireless communication unit to wirelessly transmit the second transfer rate beacon in the second period.
