To design a nationwide synthesizer paging system that includes less expensive transmitters, pagers (or receivers), and simple operation. Each city will have transmitters with one frequency, and each subscriber will carry a synthesizer pager that could be switched to any frequency in the nation; hence, subscribers can travel to different cities and still get pages just like local pages. The subscribers would be provided a list of frequen- cies for every city in the network (could be coded list).
