Abstract:

This study involves an assessment of the operational performance of four mobile network operators (MNOs) within the confines of Shiroro Power Station. The objective was to gauge, analyze, and appraise the quality of their voice and data services, subsequently offering recommendations for enhancement. Through the utilization of transmission environment monitoring software (TEMs), a comprehensive drive test was executed, and ensuing statistical analyses enabled a thorough evaluation of performance. The findings revealed that the received signal strength oscillated between -50 dBm and -110 dBm, deviating from the recommended range of -30 dBm to -70 dBm by the Nigerian Communication Commission (NCC). Notably, Mobile Network A, Mobile Network B, and Mobile Network C demonstrated excellent received quality. This observation aligned with the NCC’s criteria for received quality level. Conversely, Mobile Network D exhibited subpar received quality. Further assessments indicated that MNO C excelled in call setup time (CST), call setup success rate (CSSR), and call completion success rate (CCSR). Meanwhile, MNO A and MNO B showcased superior performance in terms of dropped call rate (DCR). In the realm of mobile internet services, MNO B emerged as the frontrunner with an outstanding latency of 2.75 ms and a throughput of 6731.8 kbps. Following closely was MNO C with a latency of 121 ms and a throughput of 153 kbps. In the data rate category, MNO A led the pack with a data rate of 38.85 kbps, trailed by MNO C with a data rate of 10.55 kbps. The study pinpointed several technical challenges contributing to suboptimal performance, encompassing terrain-related issues, inadequate transmit power, the absence of booster amplifiers at base stations, deficient coverage, and the lack of 4G wireless technology.
