Each cell is equipped with a base station, which establishes a wireless communication link with the mobile station in its service area. Several cells form a cell group (cell), and the base stations of each cell in the cell group can be connected to the mobile switching center (MSC) through cables, optical cables or microwave links. The mobile switching center is connected to the exchange through PCM circuits.
