DESIGNING HIGH-SPEED PAGING SYSTEMS

The area of pager systems is changing with the introduction of new pag ing standards, particularly FLEX, in all worldwide markets. The semico nductor concepts for new pagers are developing rapidly towards even hi gher integration. Single-chip concepts, including decoding, controller tasks, level shifting, frequency synthesizer and memory, are becoming common. Roaming requirements present an added level of complexity. Th is article examines solutions and approaches to the design of new page s and explains the software tools, hardware platforms and semiconducto r products that are becoming normal in this area.
