Satellite paging coverage system can broadcast all kinds of paging information to the area covered by the satellite. The advantages of this system are easy realization, quick construction, high reliability, and low error rate. It consists of one central station and a number of remote receiving only stations.

The paging information may be single channel or multi-channel. Multi-channel paging information can be multiplexed by the Mux installed at the central station to convert several encoded paging information into a integrated data transmission stream, and then be de-multiplexed by the Demux installed at the remote stations to convert the integrated data stream back into encoded paging information.

The system provides perfect network management system to realize the complete network management of the satellite broadcasting system.

Advantages of Satellite Paging Coverage System
