EVALUATION OF MOBILE COMMUNICATION NETWORK PERFORMANCE IN DELTA STATE, NIGERIA

Abstract

This research offers an assessment of the performance of the mobile communication network conducted in Delta State, Nigeria. The assessment is based on Quality of Service characteristics. Blocks, lost calls, speech quality, and Received Signal Strength (RSS) were all taken into account for the Quality of Service in three distinct mobile communication networks in Nigeria, which were designated as NET A, NET B, and NET C. With the help of Android Version 2.3.5 and TECNO mobile equipment (model number TECNO N3), the RSS data were collected. RF network tracker software was utilized to assess the mobile communication network providers in Nigeria that use the 900/1800 MHz spectrum. To ascertain the degree of speech quality, Mean Opinion Score (MOS)-based subjective testing techniques were also used. The subjective method was carried out in a calm setting at various times, using approved words for each of the three cell networks under examination at unique lengths. Examined were the speaking qualities of men and women. Different causes of dropped calls and low (bad) speech quality degrees were also emphasized. The complete average root mean square error (RMSE) score of the male speech excellent obtained from the three networks considered is found to be 0.601. On the other hand, invariance was the correlation coefficient value found between the male and female speech qualities. Additionally, compared to Net B and Net C, Net A has greater (better) voice quality. Furthermore, in mobile communication networks, a large percentage of dropped calls has been attributed to voice distortions. These results will contribute to the enhancement of mobile communication in Nigeria.
