Comparative Evaluation of G.S.M Quality Services of Network Performance in the Nigerian Telecommunication Industry.

This study is aimed at presenting a report on the quality of services and the evaluation of GSM network performance forvarious locations. The indicator compares the network’s capacity for calls established as against congested calls given thenumber of call attempts for six different locations. This is demonstrated in the ratio of the network capacity with respect tothe number of call attempts, established, and congested across six distributed locations. The locations were randomlydistributed; series of graphs and measurement were taken. A multi-variate analysis of variance (MANOVA), which led to theuse of a non-parametric test, Kruskal-wallis H, for ranking the difference in median. The result provided comparism of themean and the median for the optimal capacity of the attempted, established and congested calls for each location understudy. This is to enable service provider determine facilities deployed to various locations, to achieve optimal performanceand meet customer satisfaction.Key words: Telecomunication, G.S.M, Teledensity, network capacity
