Performance analysis of wireless fidelity network within the university campuses: a case study of Nigerian university

Abstract

This study evaluates the Wireless Fidelity infrastructure at a typical Nigerian University Campus taking Ajayi Crowther University as a case study, and focusing on key performance indicators such as signal strength, channel usage, and network speed across various campus locations. The analysis revealed significant disparities in signal strength, ranging from -50 dBm in the Chief Wole Olanipekun lecture room to -65 dBm in faculty buildings, and identified interference in the 2.4 GHz band as a major issue in high-density areas. Network speeds varied, with averages of 50 Mbps in lecture halls and up to 120 Mbps in administrative offices. While the current network meets basic connectivity needs, critical improvements are needed, including upgrading to IEEE 802.11ac access points, optimizing channel allocation, and increasing access point density in high-traffic zones. These enhancements aim to boost the network’s reliability and performance, though the study faced challenges with fluctuating traffic and environmental factors affecting signal consistency.
