Abstract
In this paper, we establish suitable propagation models and use them to estimate the potential of TVWS for Coastal and Morogoro regions in Tanzania. Four mostly used propagation models, Free Space, Egli, Ericsson and Hata were analyzed. We established an AM-Ericsson model from the Ericsson model, which was closest to the measured results in rural areas but still with a 25 dB difference. The results showed that Hata was the suitable model for semi-urban areas and the established AM-Ericsson model had more than 20 dB improvement from the Ericsson model for rural areas. The study found that there is up to more than 95% TV channels availability for Coastal region and 97% availability for Morogoro region. This research provides a baseline information to facilitate the estimation of the potential TV channels for secondary use in Tanzania. The study also guides a proper regulation and planning of spectrum in the country.
