| dc.description.abstract | Due to innovative data services, the number of mobile subscriptions and amount of mobile data traffic will increase significantly globally. According to Ericsson mobility report, in 2022 the number of mobile data subscribers and traffic is forecasted to reach 9 billion and 71 Exabyte per month, respectively, from the current 7.5 billion and 8.8 Exabyte per month. Likewise, the report presented that Sub-Saharan Africa will also show a faster growth rate than any other region in the globe. 2018’s Ericsson interim mobility report shows, Ethiopia is among five countries in the world that score high in mobile subscription growth. In addition, when we see historical records, market potential, and various telecom expansion plans of the country, mobile subscriber and traffic growth is expected in Ethiopia, particularly in Addis Ababa city. To accommodate the increasing mobile traffic, beside Long Term Evolution (LTE), several operators are deploying and optimizing LTE-Advanced and LTEAdvanced Pro mobile technologies. Having partially deployed LTE network in Addis Ababa, ethio telecom has not yet moved to LTE-Advanced but now considers to accommodate significantly increasing mobile subscribers, traffic and future demand of the city. To that end, there is a need of understanding techno-economically viable LTE-Advanced deployment scenarios for the local context. In this thesis, feasible LTE-Advanced deployment options are developed using scenario planning method. Following, TERA Techno-economic Analysis framework and methodologies are investigated and modified to evaluate possible LTE-Advanced deployment scenarios techno-economically assuming 6 years study period and 10% discount rate. In the framework market analysis and LTE-Advanced radio network dimensioning performed using COST-231 Hata model; existing LTE traffic, standard and demography analysis is conducted for macro and small cells, respectively. In addition, the required bandwidth for the study period is forecasted and determined. Based on resulted Net Present Value and Payback Period of techno-economic evaluation, an LTE-Advanced scenario that applies progressive deployment with out-of-band small cells is feasible for Addis Ababa but not the case for a scenario that applies full deployment with out-of-band small cells. In both scenarios it is shown that LTE-Advanced is feasible if deployed in dense urban and urban areas. | en_US |
