<p>This Paper focuses on analyzing and evaluating the performance of an existing 4G network based on handoff process in the network since there is need for Network Providers to comply with the Quality of Service (QoS) standard in their network service delivery to the consumers. The regulatory authority in Nigeria being the Nigerian Communication Commission (NCC) sets up some key Performance Indications (KPIs) that the Network Providers need to adhere to in order to ascertain if the deployed model will enhance Mobility and Handoff Management and improve QoS delivery. This research work involved a Drive Test on Mobile Telecommunication Nigeria (MTN) network using Transverse Electromagnetic Simulator (TEMS) - 15.0. Based on the applied Mobile Assisted Handoff (MAHO) technique, and weeks of Drive Test, the Received Signal Strength Indicator (RSSI) in the characterized 4G Network showed evidence of strong signals in the range of -50dBm to -80dBm within the Base Station (BS) footprint for the one week of Drive Tests in which measurements were carried out within a range of 600m radii. MATLAB SIMULINK and mathematical calculations done on field experimental data gathered, confirms compliance with NCC benchmark. Finally, we still recommend an improved performance of the network, in terms of the measured and determined values of some of the key performance indicators.</p>
