1. A paging system, comprising:

  • a satellite having a predetermined footprint for generating timing information and transmitting said timing information on a downlink channel;

    a plurality of paging sites disposed in the footprint of said satellite;

    a plurality of satellite receivers, one of said satellite receivers disposed at each of said paging sites for receiving at least the timing information from said satellite, said timing information received at each of said satellite receivers at substantially the same time;

    a paging source for generating paging information and transmitting it to each of said paging sites;

    a paging receiver disposed at each of said paging sites for receiving said paging information;

    a paging transmitter disposed at each of said paging sites for transmitting said received paging information on a paging frequency in accordance with said received timing information within a predetermined locale proximate to each of said paging sites for reception by a paging receiver within said paging locale; and

    said predetermined locales for substantially all adjacent ones of said paging sites having substantial overlap such that if one of said paging transmitters fails in its associated predetermined locale, said paging transmitters at the adjacent ones of said paging sites will provide sufficient field strength to be received by a paging receiver in substantially all locations within the predetermined locale associated with the failed one of said paging transmitters.
