摘要: A paging system includes a satellite uplink (40) for assembling information and transmitting it to (26). The (26) is then operable transmit in simulcast manner all the various regional systems (42). Each of (42) plurality towers (10) each containing receiver (50), dish (48) associated therewith transmitter (52). receivers (50) are receive transmitted from at substantially same time such that there no phase difference between any towers, regardless location. Therefore, transmitters can through antennas (12) frequency with relative delays (12). backup link (28) provided interfacing (70). In event failure or (26), (70) will directly select ones over separate frequency.
