A terminal unit for a wireless communication network includes a wireless modem, a wire network controller, and a CPU. The modem can check whether a RTS signal is inputted or not during reception of communication data, and modulates communication data and performs wireless transmission of the data in response to the RTS signal when no communication data is being received, while it temporarily outputs a CTS signal and disables it thereafter in response to the RTS signal when communication data is being received. Upon reception of a data transmission request from the terminal unit, the controller outputs the RTS signal to the modem after completion of reception of communication data when the data is being received, or outputs the RTS signal to the modem when no communication data is being received. The controller determines interruption of data transmission and outputs a RTI signal when the CTS signal from the modem is temporarily input and disabled thereafter. The CPU requests the controller to perform data transmission, performs back-off processing upon reception of the RTI signal, and causes the controller to generate a RTS signal to the modem after a determined back-off period.
