Modelagem de um enlace de comunicação ponto a ponto em microondas para a fronteira de Cuchamano

Abstract

The Professional Internship is a form of completion of the course at the Faculty of Engineering of Eduardo Mondlane University. This report presents the description of the main activities carried out during the internship period at the company Vodacom Mozambique, and the case study carried out to solve an engineering problem verified during the same. The case study is focused on the modelling or planning of a microwave communication link for the border town of Cuchamano, in order to provide 4G mobile telephony services and, at the same time create redundancy for the only transmission medium currently available in the region. In this work, the theoretical calculations necessary for the realization of the microwave link were made, based on the consulted literature and in accordance with the standards/recommendations of the International Telecommunications Union (ITU). Then, the link profile was modeled using computational tools (software). For confidentiality reasons, LINKPlanner, a microwave link planning software owned by Cambium Networks, was used. It performs calculations based on ITU-R P.526-10 (no clutter) or ITU-R P.526-14 (with clutter) recommendations and ITU-R P.530-12, ITU-R P.530-17 or Vigants - Barnett (VB) to predict NLoS and LoS paths to anywhere in the world. It is different from the software that the institution itself uses, however, the results presented are close and representative of the real model, considering that they have the same operating principle. To complement, Google Earth was used, a software that shows a 3D representation of the Earth based mainly on satellite images. In any case, all data and/or results contained in this report must be used strictly for academic purposes.
