ipBSC Base Station Controller

ipBSC Base Station Controller

The Prism-IPX ipBSC Model Version 2 is a network base station controller designed for use with the Prism-IPX PriMega series of text message handling systems for message transmission over single transmitter or multiple transmitter radio simulcast networks used primarily for paging technology.

Data for broadcast sent using Ethernet connectivity from the Prism-IPX PriMega is received by the ipBSC and retimed for transmission using GPS technology or Prism computer server time synchronized to a highly stable time standard.


The Prism-IPX ipBSC Model Version 2 is a network base station controller designed for use with the Prism-IPX PriMega series of text message handling systems.

Encoded paging data from the PriMega encoder software is sent via IP Unicast or Broadcast to the ipBSC(s) in systems with a few ipBSC’s, or to the Dispatcher module which handles sending individual data packets to many ipBSC’s. Raw paging data is sorted into dedicated protocol queues for processing when transmission algorithms are ready for the data.

At each simulcast paging transmitter site, a GPS unit is used to provide data synchronization and precise transmitter frequency control using the clock reference derived from the GPS 1 pulse per second and related timing packets. Paging data is transmitted simultaneously from each site using the GPS clock pulse as its timing source.
