Authors: *Airoboman A.E, Wamdeo C.L, Lawan S.
The paper investigated the operational performance of some GSM networks in Ota, Ogun State, Nigeria. Various call data of some subscribers that placed call from one network to another were collated. The reliability of inter-network performance was calculated using the Indices of Reliability (IR). The results obtained were graphically analyzed using the Microsoft Excel software. The results showed that the subscriber that initiate call tagged as subscriber ‘B’ had a 40% successful connection performance from other network, while subscriber with network ‘D’’ had a 90% chance to receive call from any network. Further results showed that there is a 60% chance of connectivity between similar network for D-Dl, 20% for line A-Al and E-El respectively. The weakest link in the network from the analysis was identified as line B-Bl with an average reliability value of 88% followed by C-Cl with reliability value of 94% which is lower than the reliability benchmark of a minimum of 99%.
