In a wireless communication system, which includes a fixed station device and a mobile station device, the efficiency of data communications is easily improved. In the present invention, the mobile station device comprises a connecting means to which a data terminal is connected, a transmitting means for transmitting first digital data inputted from the data terminal to the fixed station device, and a receiving means for receiving second digital data transmitted from the fixed station device and moreover, the fixed station device comprises a receiving means for receiving the first digital data, a modulating/demodulating means for modulating the first digital data and transmitting the resultant first modulated wave signal to the telephone network and for demodulating a second modulated wave signal inputted from the telephone network to form second digital data, and a transmitting means for transmitting the second digital data, so that the transmission data can be transmitted at the preset transmission rate in the wireless zone, and thus the efficiency of data communications can be easily improved.
