NETWORK PERFORMANCE AND QUALITY OF SERVICE EVALUATION OF GSM PROVIDERS IN NIGERIA: A CASE STUDY OF LAGOS STATE

Network performance and q uality of service evaluation of GSM Providers in Nigeria is presented in this paper. . The study used Lagos State of Nigeria as a case s tudy in which three major towns ? Ikoyi, Abule - Egba and Agege were covered. Since the commencement of GSM services in the country, the quality of service (QoS ) being delivered by the four major Operators - MTN, GLO, Etisalat and Airtel, has been an issue of concern both to the subscribers and the national regulatory body. For this reason a study on the performance of thes e Operators in terms of service delivery is relevant. To achieve this, Radio Frequency (RF) measurements were made using the standard drive test method. Data collected were evaluated using QoS metrics as the key performance indicators ( KPI) for determinin g the performance of each of the network provider. Using call drop rate (CDR), one of the performance indicators, it was observed that Etisalat had the least value of 0.6% of all the calls initiated during the test
