Coverage Estimation of GSM System Considering Spectral Efficiency, Interference and Cell-Sectoring

Abstract

In this work, the capacity and coverage area of GSM system have been studied. Channel capacity estimation considering spectral efficiency, system capacity estimation considering interference, cell sectoring, cell splitting, microcell zone concept and power control also been studied. MATLAB 6.5.0.180913a Release 13 has been used for simulation and performance evaluation of capacity and coverage in GSM system. A simple Microsoft Excel tool for GSM Link budget calculation has been formulated. Path loss for uplink and downlink has been calculated using Link Calculator software considering 3-sector antenna. Different areas such as urban, sub-urban and rural areas have been considered for this purpose. RF coverage planning has been also done to improve the capacity. Effect of MS antenna height, BS antenna height and effect of output power of BS have been studied for different areas. Analysis reveals that coverage area improves significantly considering spectral efficiency, interference and cell sectoring. As an example, Google Earth 4.3 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.
