| dc.description.abstract | The popularity of broadband Internet services has increased significantly over the past few years. Similarly, the development of mobile network technologies has seen rapid growth. Due to these trends, Fifth Generation (5G) Fixed Wireless Access (FWA) networks have been proposed as a potential competitor to other broadband access technologies, such as Optical Distribution Network (ODN). However, technological advancement itself cannot show the performance, acceptance, or economic viability of an investment without a detailed technical and economic feasibility assessment of possible broadband deployment alternatives. This thesis conducts a techno-economic comparison between 5G FWA at mid-band frequency range and Gigabit Passive Optical Network (GPON) based ODN to provide broadband services for residential users. It presents a techno-economic analysis of four possible deployment scenarios: namely, two scenarios (Sc-1) and scenario (Sc-2) based on 5G FWA using new and existing infrastructure, respectively. The other two scenarios (Sc-3) and scenario (Sc-4) are GPON-based ODN using new and existing infrastructure, respectively. These scenarios are evaluated in the context of the capital city of Ethiopia, Addis Ababa, around an area called Tulu Dimtu. Data collected from the operator, ethio telecom, serves as main source of information. For the evaluation, the most popular and widely used techno-economic tool, called Techno-economic Results from the Advanced Communications Technology and Services (TERA), is modified and implemented including network dimensioning, revenue modeling, cost modeling, and economic analysis. For all analyses, 10-years study period and 10% discount rate are considered. The analyses were evaluated using standard economic indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PBP). MATLAB and Microsoft Excel are used for the implementation. Achieved result shows that the PBP of the scenarios are: 4.48, 3.75, 4.63 and 4.37 years for Sc-1, Sc-2, Sc-3, and Sc-4, respectively. Based on NPV results, all scenarios have positive NPV for the study period and greater IRR value than the defined discounted rate. Sensitivity analysis shows that revenue is the most sensitive parameter over the other parameters. The findings indicate that all scenarios are deployable, but they should be deployed based on requirements. | en_US |
