Abstract: In this work, the capacity and coverage area of GSM system have been studied. This paper presents the importance of using link budget calculations, determining the path loss and cell range for RF coverage planning and improving capacity using cell-sectoring. The major contribution is to estimate the coverage of GSM system which depends on BS antenna height, transmitting antenna gain, output power of BS for propagation environment such as rural, sub-urban and urban case. MATLAB has been used for simulation and performance evaluation of capacity and coverage in GSM system. Path loss for uplink and downlink has been calculated using Link Calculator software considering 3-sector antenna. Analysis reveals that coverage area improves significantly considering spectral efficiency, interference and cell sectoring. As an example, Google Earth and Radio Works software have been used to estimate the coverage area for a particular area. A 3D coverage map has been formulated using this result.
