Abstract
In this work, performance of four mobile network operators (MNOs) was measured, analyzed, and evaluated in Shiroro Power Station environs and recommendation were made to improve the quality of their voice and data services. Drive test was performed using transmission environment monitoring software's (TEMs) and statistical analysis was done for performance evaluation. The results show that the receive signal strength level was between the ranges of -50dBm to -110dBm as against the standard range values of -30dBm to -70dBm, recommended by the Nigerian Communication Commission (NCC) and the receive quality for Mobile Network A, B and C were observed to be Excellent. This imply that MNO A, B and C met the NCC recommendation in term of receive quality level. However Mobile Network D receive quality level was observed to be poor. MNO C offered the best quality of service in term of call setup time(CST), Call setup success rate (CSSR), Call completion success rate(CCSR) whereas in term of dropped call rate (DCR) MNOA and MNO B were the best. MNO D receive quality signal was observed to be poor in the studied area. Mobile internet service of MNO B was observed to be the best in term of Latency and Throughput follow by MNO C but in term of data rate MNO A was observed to be the best followed by MNO C. Certain technical issues were observed to be responsible for identified poor performances.
