Examination of call setup success rate and dropped call rate for 4g networks in Yenagoa-southern Nigeria

This study compares the call setup success rate and dropped call rate of four mobile telecommunication networks operating in Yenagoa, Southern Nigeria, to industry benchmarks and competitor networks in an effort to identify areas for improvement, set performance targets, and establish a relationship between them. The results show that the four networks (MTN, 9mobile, Airtel, and Globacom) performed within the regulator's benchmark in the majority of cases, while noting many instances where their performance fell below the benchmark. The maximum value obtained within the period in view for call setup success rate was 99.77% and it was gotten from MTN while the minimum value obtained was 94.07% and it was from Globacome.; conversely for dropped call rate, the maximum values obtained within the period in view was18.52% and it was in March 2016 for Globacom while the least value recorded is 0.00% and it was in September 2018 for 9mobile. For Airtel, 9mobile, Globacom, and MTN, the correlation coefficients between CSSR and DCR were -0.34, -0.47, -0.60 and -0.69 respectively. The four networks' negative correlation coefficient values show that, in every scenario, a rise in CSSR results in a corresponding drop in DCR  and vice versa.
