    The measurements were carried out at different geographical positions of the town at varying time intervals. The study revealed several levels of KPI achievements by the different networks with Globacom performing best, coming tops in twenty-three 23 indicators out of the thirty-seven 37 considered followed by Zain and then MTN. It also revealed that the networks achieved some NCC QoS benchmarks and failed in some other notable ones. The coming of GSM has radically transformed people's way of life, brought economic prosperity to many and made the country a very important telecommunication destination in the world.

    GSM revolutionalised business environment, enhanced social relationships, empowered the people economically through creation of mass employment and has equally become a major source of revenue for the government.

    Despite all these, focus has gradually shifted from providing coverage to provision of quality service.

    There have been numerous complaints from all parts of the country regarding call and voice quality, interconnectivity, billing integrity, inability to make calls, poor network reception and total lack of service etc. As far back as , NCC had warned telecom operators to improve services rather than concentrating solely on generating revenue.

    The regulator felt that customers had had enough of paying for unreliable network performance, and it considered regulation to improve the standard of service in the industry. NCC has been doing all things possible to compel the operators to improve on their services, recently adding that the operators have been cooperating and have promised to improve on their services [1].

    This situation has since improved but as with the rest of the country, some lapses are still being experienced. This research is concerned with evaluating the performance of GSM Network service providers to ascertain the level and efficiency of their service provision in Okada, hometown of Igbinedion University.

    The scope of this research is limited to measures on some technical parameters and Value Added Service Key Performance Indicators KPIs relating to network Quality of Service QoS since this is of more concern to subscribers and more useful to network service providers in issues of network optimization for the benefit of subscribers. The performance of the GSM network depends on several factors which could positively or negatively affect its quality of service.

    Interference is recognized as a major cause of poor quality and dropped calls. As the subscriber density on a network increases the limited number of available channels is reused.

    Multi-path problems can also occur in the network when a carrier signal is reflected off buildings or other physical obstructions. In a cellular radio system, the quality of the connection between a base station and a subscriber terminal varies continuously.

    This variation is due to disturbances in the radio path and to the attenuation of radio waves as a function of distance [2]. It has been found that path loss varies with increase in separation distance from base station, power reception level also varies with distance, being stronger outside a building than within, while signal attenuation factors within buildings vary according to the material used for its construction [3].

    Another reason observed to be the possible cause of GSM poor performance is the use of GSM Gateways which are devices containing one or more GSM SIMs whose original purpose was to allow fixed line telephones to interface with mobile networks where the latter are connected to the device which then connects calls made by them to the GSM network using the SIMs contained within it.

    Research Methodology Research framework: There are several reasons why performance evaluation is a necessary part in any GSM network investigation. They include Error detection and Correction; traffic load measurement; resource availability measurements; Quality of Service measurements; and statistical data acquisition.

    The goal of performance measurement PM could be for network planning; network operation; network optimization; grade of service or marketing and control. The scope of this research was limited to reasons and goals of PM relating to quality grade of service.

    These KPIs give insight into determing how well the network is doing, thus knowing if it is meeting up or falling short of the desired expectations.

    The chosen parameters were viewed to be of direct relevance as they relate to the subscribers usage and monitoring them can lead to network optimization for the benefit of subscribers if operators strive to conform to agreed standards.
