All RADIO-related functions are performed in BBS the base station controllers (BSCs) and the base transceiver station (BTSs). BASE STATION CONTROLLER (BSC): The BSC provides all the control functions and PHYSICAL links between the MSC and BTS. It is a high-capacity switch that provides functions such as handover, cell configuration data, and control of radio frequency (RF) POWER LEVELS in the base transceiver stations. A number of BSCs are served by an MSC. BASE TRANSCEIVER STATION (BTS): The BTS handles the radio interface to the mobile station, the BTS is the radio EQUIPMENT (transceivers and antennas) needed to service each cell in the network. A group of BTSs are controlled by a BSC.
