Patent ID: 8804590

Claim:
A communication apparatus comprising: a wireless communication device configured to perform wireless communication with one or more terminal apparatuses; a transfer rate setting device configured to set a transfer rate of the wireless communication performed by the wireless communication device; a beacon generation device configured to generate a beacon which specifies a first period in association with a first transfer rate and a second period in association with a second transfer rate lower than the first transfer rate; and a control device configured to cause the wireless communication device to wirelessly transmit, for every predetermined period, the beacon generated by the beacon generation device, wherein when causing the wireless communication device to wirelessly transmit the beacon, the control device is configured to cause the transfer rate setting device to set the transfer rate different from a transfer rate previously used for wirelessly transmitting the beacon and cause the wireless communication device to transmit the beacon to the one or more terminal apparatuses, and wherein, when the wireless communication device fails to transmit a data signal at the first transfer rate in the first period, the control device is configured to cause the wireless communication device to retransmit the data signal at the second transfer rate in the second period.
