Glossary definition of Base Station Identity Code

Also known as: BSIC

Base Station Identity Code (BSIC) is a 6 bit 'colour code' broadcast on the SCH (Synchronisation Channel) in GSM systems, which uniquely identifies the beacon frequency.

The BSIC is broadcasted in order to identify the NCC (Network Colour Code) and the BCC (Base Station Colour Code) to the Mobile Stations in the area. Adjacent cells in the cellular system will have different 'colours' or BSICs.
