A generic block diagram in shown in the figure: A BS consists of a base transceiver system (BTS) and a BSC. Cellular System Architecture The increase in demand for cellular services combined with the limited availability of the frequency spectrum available for commercial cellular use has promoted engineers to look for techniques to use the available spectrum as efficiently as possible, without sacrificing coverage area.
The RAN manages the radio spectrum, making sure it is used efficiently and meets the quality-of-service requirements of every user. It belongs to the second generation (2G) of cellular technology, and it is a Digital using circuit switching concept to transfer voice and data. A cellular network is a radio network distributed over land through cells where each cell includes a fixed location transceiver known as base station.
