Performance Analysis of Gsm Networks in Minna Metropolis of Nigeria

Abstract

This work examined the performance of GSM networks (P, Q, R and S) in Kano Metropolis, Kano State, Nigeria, where the Key Performance Indicators (KPIs) were used as a key asset for carriers and subscribers alike. The Ericson W995 Phone with built-in Transmission Environmental Monitoring System (TEMS POCKET) software package was used to generate the log files from the active GSM networks. The post analysis of these log files identified problems of parametrical issues. The research results revealed out that the four carriers failed to achieve NCC minimum targets for CSSR, HOSR and call blocking respectively. More than 40% of the samples had poor quality and the five coverage groups were defined in terms of RXLEV and RXQUAL, while group 1 and 5 were the best and worst groups respectively since it comprised both the best and poor RXLEV and RXQUAL. The drive test maps were inspected and found out that the four carriers experienced one or more type of signal interruptions. The work validated the claim made by the NCC; Nigeria Communication Commission, that the carrier P had the best network coverage nationwide. Parametrical optimization was given as a way of network improvement for better reception and huge amount of revenue generation.
