Abstract EN
This paper presents a radio propagation model for the UHF band that is designed for an outdoor scenario in the Amazon region of Brazil and comprises city, water, and forest environments.
The model is designed for the Mobile and Home Digital Television (M-DTV and H-DTV) services.
In the case of M-DTV, the electric field is calculated at user height, while for H-DTV it considers a fixed antenna on houses roofs.
The field calculation is based on Geometrical Optics (GO) and the Uniform Theory of Diffraction (UTD).
The results for M-DTV show a good agreement with measurement data in an Amazonian city (Belém) for 521 MHz.
Different parameters of the proposed model are analyzed: the transition zone city-water, the level of water, the incidence angle in the forest, and electrical parameters for forest.
Finally, the comparison that was made between the electric fields for H-DTV and M-DTV shows a difference of up to 19 dB.
