| dc.description.abstract | This thesis describes the conceptual expressions required for network coverage and capacity limiting factors, examines service quality issues, and presents practical solutions to problems common to sub-optimality of Ethio Telecom cellular Code Division Multiple Access (CDMA) networks. The target of radio network optimization is to simultaneously maximize the system coverage and capacity. This thesis addresses the impact of antenna height, tilt and power on network coverage and system capacity. Moreover, the impacts of the aforementioned elements were investigated using MATLAB simulation tools. Accordingly the goal of the investigation is to have as high signal strength as possible in the area where the cell should be serving traffic. The paper also exposes the work carried out via drive test on selected sites located at Addis Ababa, and presents optimization done and recommendation given to improve network coverage and capacity of the cited area. Trade off between several system parameters such as operating frequency, voice activity factor, Uplink threshold, interference factor, data rate and bandwidth are considered to optimize the capacity and coverage of the network. Since, managing system interference by precise power control is a very critical concept for CDMA; reverse link interference analysis, and their effects are also studied.
