ABSTRACT
The thesis involves the evaluation and selection of appropriate Key Performance Indicators (KPIs) to improve network performance. This thesis studies the key performance indicators of M-tel Network, (Area VI Kaduna), the Base Station Controller (BSC) is considered with particular emphasis on peak period by processing and analyzing the Network KPIs recorded. In network improvement it is exceptionally important to determine what the critical system metrics are or key factors that need to be monitored to determine what is simply the quality to meet or if possible exceed the expectations of the subscribers. The data on the network has been analyzed which revealed that, the network was found to be prone to down time as a result of over reliance on Nigerian Telecommunications (NITEL) transmission. The implication of the results show gradual decline in subscriber base, frequent call drops and handover failure as a result of frequent power outage. Appropriate suggestions necessary to improve the Network for optimal performance were discussed and recommendation made.
