WiMAX is a popular broadband solution with diverse applications. With several advantages such as low cost applications and last mile solution for broadband wireless access, WiMAX will no doubt help bridge the ever increasing digital divide in many SubSaharan African countries. Many countries Sub of the Sahara have recently started deploying WiMAX to offer subscribers affordable broadband internet service. Because of the peculiar conditions in Sub- Sahara Africa, critical design and optimization techniques will be vital in making WiMAX networks deliver as expected by subscribers. In order to achieve maximum capacity while maintaining an acceptable grade of service and higher network performance of these newly deployed networks, the effect of interference should be catered for. This paper presents Network simulations results of a newly deployed 4G-WiMAX network deployed in Accra and Tema municipality, Ghana. A Monte Carlo simulation has been used to study the total interference in the network and the results presented. Finally the Network performance is evaluated through measurements of Received Total Wideband Power (RTWP) and outdoor interference and the results compared.
