BASE STATION PAGING
Base Station Paging is the one of simplest paging confi gurations and is shown in Figure 2-2. The
paging encoder (or terminal) connects to an MT-4E transmitter, through the paging modulator, for
broadcast over the local coverage area. A third party paging encoder generates the paging format for
either analog (tone and voice) or digital display (numeric output). The MT-4E transmitter then sends the
radio signal to the handheld pager. Optional high-power power amplifi ers are available to extend the
coverage area.
