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