Abstract

Neste artigo é demonstrado um exemplo de dimensionamento de um sistema de micro-ondas com o objetivo de ligar as cidades sul-mineiras de Varginha, Santa Rita do Sapucaí e Pouso Alegre, fazendo uso do Software Radio Mobile. Os parâmetros usados nas simulações são baseados nas especificações de equipamentos reais utilizados na distribuição de sinais de Televisão Digital no Brasil.

Dimensioning a microwave signal distribution system for digital tv using Radio Mobile software

This paper presents a designing example of a microwave system with the objective to connect three towns located in the south of Minas Gerais State namely, Varginha, Santa Rita do Sapucai and Pouso Alegre, making use of Radio Mobile Software. The parameters used in the simulations are based on real equipment specifications for signal distribution Digital TV in Brazil.

Keywords: Link budget. Point-to-point. Digital TV. Radio Mobile.
