They are named as macro, micro, pico, femto and umbrella cells. All the cells have different coverage area, and are used differently as per the requirement of a particular area. The horizontal radius of a cell depends on the antenna height, gain and propagation conditions. The range of a cell can go from few hundred kilometers to several tens of kilometers. One of the key features on GSM is Subscriber Identity Module i.e. SIM. GSM has played a major part in the evolution of wireless mobile communication.
