In competitive telecom industry customer satisfaction is the single most considerable matter and that depends only on quality of service (QoS) of wireless networks. The major part of the GSM cellular mobile telecommunication system structure is radio frequency related. So that, the quality of the network is relate mostly depend on radio functions. The major expectation is the network should cover whole area as planned the network is free from interference and reliable wireless communication.RF Network planning for GSM is a systematic project covering the whole process of network building comparison to radio transmission theory, from antenna feeder index analysis to network capability forecast, and to test of network performance and system parameter for optimization purpose. In this paper firstly a clear form of GSM cellular system has discussed. After that a complete planning of RF network for GSM has discussed. After successful planning, RF survey, system designing and installation and debugging are performed. Then a BTS is connected with live wireless network to be given opportunity to customers for mobile communication.
