Abstract

This work presents the study of the call quality provided by the two CDMA service operators within Epe town of Lagos State, South-West Nigeria by collecting and analyzing call data from the Network Operation Centre in an attempt to evaluate the call quality parameters as provided by these operators. The result of the analysis is then compared with that those specified by the Nigerian Communication Commission NCC which is the main regulatory body for telecommunication operations in Nigeria. In this work, various call quality parameters were being evaluated for two CDMA mobile operators, that is, Operators 1 and Operator 2 with existing network infrastructures within Epe town. A total of three parameters were evaluated. These parameters are Ec/Io, Rx_Level and Tx_Power. In the course of this research, the six call quality parameters and the quality of services provided by two CDMA network operators were investigated, the research outcome shows that both operators provided a very good quality of services as specified by the Nigerian Communication Commission (NCC) during the period within which this research work was carried out.
