| dc.description.abstract | Mobile Worldwide Interoperability for Microwave Access (WiMAX) is a broadband wireless technology based on the IEEE 802.16e standard. It is designed to provide voice, data and video services that require high data rates for fixed, nomadic and mobile users moving at vehicular speeds greater than 120 km/hr. Growth trends of voice and data traffic in various African countries reflect a huge increment in recent years. Currently deployed second and third generation telecommunication technologies will eventually struggle to swallow this perpetual traffic growth. This signals an eminent need to ultimately resort to deploying fourth generation (4G) technologies such as WiMAX that offer better throughput and coverage. This presents an opportunity/market potential for WiMAX or other 4G technologies. In order to deploy WiMAX in any given metropolitan area, it is imperative to perform dimensioning and radio network planning steps. The IEEE 802.16e standard offers several options/choices in its physical and medium access control layers. Within these choices, this thesis work focuses on carving out a mobile WiMAX package that fits a pre-defined coverage and capacity requirement of Addis Ababa city. The basic dimensioning steps for the access and core network are outlined and conducted using the geographic and demographic data of the aforementioned city. Radio network planning tools such as EDX-PRO and ATTOL cost in the order of thousands of US dollars. Therefore, in this research, a Radio Network Planning (RNP) tool/MATLAB program that operates on a selected propagation model and a digital terrain model database is developed and used. This thesis work, to the best of my knowledge, is the first research/case study to be conducted taking capacity and coverage requirements of developing nations. It is also the first research that is not constrained to capacity and coverage planning via theoretical analysis. Theoretical coverage estimations make use of empirical propagation models without any special consideration to the specific terrain type. The development of the RNP tool allows us to perform a more accurate coverage analysis based on actual terrain parameters that are extracted from a digital map. The RNP tool is used on five distinct metropolitan areas with different terrain type, namely, Bole Medhanialem, Gerji, Meskel Square, Piassa and Sidist Kilo. The average coverage per base station is computed from the results of these five areas. This process is useful in forecasting the total number of base stations required to offer the service on every corners of Addis Ababa or a selected portion of the city. | en_US |
