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.
