Interference is prevented and radio transmission quality is improved. A radio station (1r) performs communication by the use of a radio signal (d1). A radio station (2r) receives a radio signal (d2) which is indistinguishable from the radio signal (d1). A radio station (3r) is in a radio communication area of the radio station (1r) and a radio communication area of the radio station (2r). A communication format conversion unit (21) generates a radio signal (d2a) by converting a communication format of the radio signal (d2) to a communication format which is distinguishable from the radio signal (d1), and communicates with the radio station (3r) by the use of the radio signal (d2a). |
