BCH - Broadcasting Channel

A Broadcast Channel (BCH) is a downlink channel in a GSM system that is used by the base stations to provide signalling information to the mobile stations. The mobile station needs this information to find a network, synchronize with it and to connect to it.

There are three types of broadcasting channels:

  1. Broadcast Control Channel (BCCH),
  2. Synchronisation Channel (SCH),
  3. Frequency Correction Channel (FCCH).
