Caracterização banda larga na faixa de 2,5 GHz em áreas de vivência com predominância de vegetação para projetos de parques digitais

Abstract

Wireless communications networks are in many cases the best solution for a range of needs presented by small and large users. Whether for technical feasibility reasons or to present a lower cost of project implementation. Nowadays, the movement for the universalization of internet access has led to a rapid growth in the popularization of broadband wireless networks. This has been evident, for example, in the many digital squares deployed by Brazil abroad. Thus, there has been a constant search for the improvement of these broadband networks, which runs through the need to study the radio channel propagation through parameters that describe them. This work presents experimental results that allow to characterize in broadband the behavior of the mobile radio channel in an environment with predominance of vegetation, which will serve as data base that will help in the wireless systems design of regions with predominance of vegetation which future may become digital squares. For this, measurement campaigns were carried out on the unlicensed 2.5 GHz frequency.
