Abstract
Now a day’s internet is one of the most important things in our daily activities. Providing broadband internet by currently prevailing technologies for all people is challenging task especially for communities who live in rural and remote areas. One possible solution to provide broadband internet for rural areas is by using wireless technologies which work at unused spectrum. One of the candidate technologies which can minimize the problem of the rural broadband connectivity is a band which is allotted for terrestrial TV broadcasting but not used; referred as TV white space. The work of using TV white space for rural broadband internet service has been started in different parts of the world.
In order to deploy TV white space network for rural Ethiopia, the government’s policy toward the use of communication media and the pattern of community settlement will affect the network architecture. In Ethiopian scenario, it is assumed that available telecom infrastructure will be used for backbone network; since Ethiopian government takes monopoly of all communication media and there will be no private service provider. From the simple mathematical computation, it is assumed that Okumura-Hata path loss model can be used for rural Ethiopia.
Even though ample amount of spectrum is allocated for terrestrial TV broadcasting in Ethiopia, only fraction of it is being used and it will be available for other secondary applications. Finally, this thesis showed that TV white space is financial feasible for rural Ethiopia compared with currently prevailing technologies even though handset cost is unaffordable.
