Evaluation of Mobile Communication Network Performance

Abstract

This study presents evaluation of mobile communication network performance carried out in Nigeria; it aims to evaluate the performance of mobile communication network based on Quality of Service parameters. The Quality of Service considered blocked calls, dropped call, speech quality and Received Signal Strength (RSS) in three different mobile communication networks with the following nomenclature NET A, NET B and NET C in Nigeria. The RSS data were obtained using TECNO mobile equipment, with model number TECNO N3 and Andriod Version 2.3.5, with RF network tracker software used to evaluate the Mobile communication network providers operating on the 900/1800 MHz spectrum in Nigeria. Also, subjective measurement methods using Mean Opinion Score (MOS) were deployed to determine the speech quality level. The subjective technique became accomplished in a quiet location at diverse instances, with endorsed sentences at one-of-a-kind durations respectively for the three cell networks below consideration. The investigation was for a period of one year, from June 2014 to July 2015 at Ambrose Alli University campus, Ekpoma. The male and female speech quality was examined, also, comparison analysis became finished from various networks to decide their speech fine, the utilization of different statistical techniques such as Root Mean Square Error (RMSE) and Correlation Coefficient. Additionally, different reasons of drop calls and low (poor) speech high-quality degrees were highlighted. It is determined that the full average RMSE value from the male speech excellent received from the 3 networks taken into consideration is 0.601, while Correlation Coefficient value got between male and female quality of speech was in variance. Also, Net A has higher (better) speech quality than Net B and Net C. In addition, speech distortions have led to high number of drop calls in mobile communication networks. It was observed that the average received signal strength from Net A is -75.67 dBm, while Net B is -87.83 dBm and Net C is -79.00 dBm against the recommended RSS value. It was observed that Net A signal strength is more linearly distributed compared to Net B and Net C networks with a value of 0.043 MSR, while the total least average or mean value is obtained from logarithmic distribution of 0.402.
