Performance Analysis of 4G Technology Across Mobile Network Operators in Nigeria Using Evolve Radio Access Bearer Channel Drop Rate

This study aims to evaluate the performance and reliability of 4G technology across mobile network operators in Nigeria by analyzing the Evolved Radio Access Bearer (ERAB) channel drop rate. Covering a 36-month period from January 2021 to December 2023, the research seeks to provide insights into how well these networks meet the Nigerian Communications Commission (NCC) benchmark of 2% for drop rates, thereby reflecting their capacity to deliver quality service. Data obtained from the NCC were analyzed using graphical and statistical methods to identify trends, strengths, and areas for improvement. Results reveal that all networks consistently maintained ERAB drop rates within the NCC threshold, demonstrating compliance with regulatory standards. MTN consistently emerged as the top performer, followed by Airtel, while 9mobile and Globacom showed relatively higher, but still compliant, drop rates. This study underscores the importance of network optimization and offers actionable recommendations for further enhancing reliability and user experience in Nigeria's mobile networks.
