Currently deployed cellular wireless networks such as GSM/CDMA/LTE are infrastructure type. Cellular network consists of central entity known as base station and mobile devices as MSs (Mobile Subscribers). If MS-B wants to communicate with MS-C, communication happens via base station(BTS) as shown in the figure-1.

Before development of Cellular network users are served using very high power transmitter which used to cover range in Kms but at the cost of high power. Later on cellular networks consisting of many low power transmitters covering more subscribers within its coverage reach have been designed and developed. The main function of Cellular network is to increase more and more subscriber capacity. Due to low power transmitters, the area is divided into small cells, each served by one base station(i.e. BTS in GSM) each. All the base stations are connected in different topology configurations. These BTSs are connected with MSCs and other cellular infrastructure systems.

There are two types cells viz. Macrocell and microcell. Macrocell covers 1 to 20Km while Microcell covers 0.1 to 1 Km. Macrocell uses high power transmitters while microcell uses low power transmitters. Access techniques such as TDMA, FDMA and CDMA are mainly employed in order to enhance the supported capacity of subscribers in a cellular network. It is referred as single hopped system.
