dc.description.abstract Digital television and mobile broadband services are significantly progressing for the past three decades; this progress, in turn, is putting a burden in the available spectrum. Two of the factors that contribute to the burden are: underutilization of the spectrum occupied by the previous analogue television transmission and congestion of the spectrum due to several wireless services supported by the spectrum. In Ethiopia, there are a limited number of terrestrial television channels and a single mobile service provider. Hence, there is no imminent challenge from spectrum scarcity at the present. However, as more television services commence in the future and the telecom infrastructure expands further, where both are in the immediate plans of the Government of Ethiopia, spectrum scarcity will likely be encountered. Digital dividend, which creates an opportunity in making use of the underutilized spectrum, is a promising solution for the problem facing the spectrum. Digital Dividend is a free spectrum band that will be created as a result of the transition from analogue to digital terrestrial television transmission. This spectrum can be used to support emerging services from the broadcast and telecom sectors. Therefore, a proper frequency resource planning that accommodates the two wireless systems is needed sooner or later. In light of this, this thesis shows how the resource can efficiently be used without a considerable interference impact between the two systems. As the world has sought the digital dividend as a hopeful solution in dealing with spectrum issues, this paper discusses the context of Ethiopia's spectrum issues Digital Dividend and its Opportunities for Emerging Wireless Services: the Case of Ethiopia Page IV in proposing the analogue switchover and showing coexistence among other wireless services. The coexistence and compatibility studies help radio planners and national frequency regulator bodies to come up with new management of the frequency resource. This facilitates a way forward for designing a standard spectrum plan before many wireless services begin to operate. In this study, the wireless environment of the City of Addis Ababa is analyzed with the possibility of applying the study for the rest of the country as well. The results obtained identify the region 700-1429 MHz band as a digital dividend out of which 795-1429 MHz band can be used for non television wireless services, particularly for broadband mobile services such as the Long Term Evaluation (LTE). en_US
