Abstract
A wireless personal mobile terminal in a cellular data network includes a packet radio transceiver for communicating with cellular base stations and a paging receiver for receiving paging signals from a paging transmitter serving a large geographical area. The wireless personal mobile message unit has power-saving features built into the signal format. This personal mobile message unit accommodates many communication applications due to the high bandwidth and the low latency achieved in the cellular data network. Low-power operation and wide coverage is achieved using existing one-way paging infrastructure. The wireless personal mobile unit can be achieved inexpensively by modifying a conventional one-way pager.
