A method of adapting synchronous transmission to the rules that apply to asynchronous transmission in a radio medium. In asynchronous transmission, it is decreed that the transmitter/receiver operates in monitoring mode for a given short period of time (tm), in order to establish whether or not transmission shall take place. The synchronous transmission is, for instance, a TDMA transmission for a personal telephone system active over short distances (10-200 m). According to the proposed method, the radio medium is monitored by a synchronous transmitter (PT) over a brief time period (G) between two time slots (T1, T2) and the power (Pm) received is measured and compared with a given prescribed threshold power (Pt) in accordance with asynchronous rules. Permission to transmit can be given on the basis of the result of this comparison.
