NCC - Network Colour Code

The Network Colour Code is broadcasted as part of the BSIC (Base Station Identity Code). It consists of 3bits, which are used to differentiate between operators utilizing the same frequencies. An example of when this will be required is on an international border when both operators have been allocated the same frequency or frequencies.
