ABSTRACT:
A satellite (26) is operable to transmit timing information to a plurality of paging sites having towers (10) associated therewith and satellite receivers (48) associated therewith. This provides a simulcast transmission of the timing information such that the timing information arrives at each of the paging sites at substantially the same time. The data that is transmitted from a central station over a radio controlled link from an antenna (16) to a plurality of antennas (14) over a wireless communication link. Data is transmitted, due to the distances have a delay associated therewith. A synchronization network in the form a correlator (157) and a delay loop (158) provide for a delay between the data from the RCL (32) and the transmitted data from an antenna (12) to be adjusted such that the data transmitted from the paging transmitter (12) to the pagers (18) are transmitted from the paging transmitter antennas (12) at substantially the same time.
