Performance evaluation of GSM and WCDMA networks: A case study of the University of Ilorin

Abstract

Mobile networks are evaluated to assess and measure network performance, thereby, improving customer satisfaction and revenue generation. This paper focuses on evaluating the performance of mobile networks, identified as Operator A, Operator B, Operator C, and Operator D, providing voice communication service(s) in the University of Ilorin, Ilorin, Nigeria. A drive test method was used to obtain the key performance indicators (KPIs) for accessibility, retainability, mobility, and service integrity, in comparison with the NCC-defined target for each. The KPI results were aggregated to give the overall network performance for each network operator across the selected drive route – main campus and staff quarters. The Wideband Code Division Multiple Access (WCDMA) network performance in both locations is far behind the Nigerian Communications Commission (NCC) defined KPI target and below the customers’ satisfaction, while the Global System for Mobile Communications (GSM) network performance in both locations is permissible. This paper recommends that network operators regularly monitor, optimize and improve on the services provided to subscribers as well as invest in network resources to meet customers’ satisfaction as well as increase revenue generation.
