This invention is related to the method and apparatus to accomplish wide area paging. Currently there arc limited nation-wide paging services using one of a few dedicated nation-wide frequencies such as in the 900 MHz domestic paging allocation. A roaming pager simply monitors one frequency for messages targeted for its user. Using a common frequency at 900 MHz is possible since that band was previously unallocated. The popularity of this nation- wide paging service has steadily grown as the country and world get smaller. The capacity of these frequencies will eventually not be able to meet the demanded need. Certainly advanced digital modulation schemes will be used in concert with the present signalling schemes to make more efficient use of the available physical channels to support more users. These pagers, being more complicated, will certainly cost more than today's pagers. An alternative to provide both low cost pagers and an economic fixed end network to provide nation-wide service, is sought.
