Abstract
In a radio paging system wherein paging calls are initiated by a central radio station and sent over lines to subordinate radio stations for transmission to paging devices, the subordinate stations are synchronized to transmit paging messages by introducing time delays between reception of a message from the central radio station before transmission, the time delays being functions of the message transmit times via the lines to the various other stations as well as the radio propogation time between the other stations.
