The introduction of 4G LTE communication technology was basically designed to meet the increasing demand by users for high quality multimedia services, data communication speed and improved quality of service (QOS). It is pertinent to note that with an ever-increasing subscriber base, it is essential to assess and analyse the network performance. To perform this task, there is need to use the key performance indicators. This research study tends to evaluate KPI’s gathered from field measurements, using statistical approach to establish the performance and determine the present condition of the quality of service offered by a 4G LTE network in Port Harcourt, Nigeria. In this study, drive test approach was adopted to measure the KPI’s and analysis was achieved with the use of TEMs Discovery software adopting statistical approach. The result showed the value range of the measured KPI’s were; RSSI (-90, -49.7dBm), RSRP (-117.7, -68.6 dBm), RSRQ (-14.2, -22.8dB) representing minimum and maximum values. The probability distribution of the various KPI’s indicated that the best signal ranges were distributed as 38.21%, 69.63% and 65.63% for RSSI, RSRP and RSRQ respectively. The KPI parameters were within acceptable range, though require optimization to provide better service for a greater population.
