<p>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 is described here for adjusting the time of sending the characters by the radio stations, which earliest obtain the order to send the personal paging call, to introduce a time delay so that all transmitters (2:2, 3:16) send the characters of the message simultaneously. </p> |
