Abstract
In transmission by radio of personal paging calls synchronous radio transmission from several transmitters is often used, i.e. the transmitters send on the same frequency. The characters of the call must also be sent simultaneously from the transmitters so that they shall be correctly comprehended by the receivers. A method and an apparatus are described here for synchronizing the separate transmitters (2:2, 3:16) such as to transmit on the same frequency.
