The terminal device includes: an antenna; a reception section receiving, from the control device, via the antenna, data and a beacon containing control information indicating the sequence and its timing; a transmission section transmitting data to the control device via the antenna; a data volume determining section determining whether a transmission can be completed within a predefined period; and a control section controlling, within the period, the reception section to receive the data and the beacon, and the transmission section to transmit the data, and when the data volume determining section determines that the transmission cannot be completed, further controlling the transmission section to, determine a next-to-be-used channel based on the control information, switch to the channel after the period, and continue the transmission.
