Abstract

MÉTODO E EQUIPAMENTO PARA REALIZAR AVALIAÇçO DE CANAL EM UM SISTEMA DE COMUNICAÇçO SEM FIO. São providos um sistema e método para classificar canais em um sistema de comunicação sem fio de saltos de freqúência. Uma máquina de coleta de dados opera para obter as métricas de canal indicando o nível de interferência para cada canal utilizado pelo sistema de comunicação sem fio. Uma máquina de análise de dados funciona para prover um mapa de canal para saltos de freqUência adaptativos (AFH) e/ou um mapa de canal para evitação de canal. Mais especificamente, a máquina de análise de dados funciona primeiramente para filtrar as métricas de canal para remover as métricas de canal indicativas de interferência de saltos de freqUência. A seguir, os canais são divididos em um número de blocos de canal cada um incluindo pelo menos dois canais adjacentes. Para cada bloco de canal, as métricas de canal dos canais dentro do bloco de canal são combinadas para prover uma soma de métrica. A máquina de análise de dados opera então para classificar cada canal como utilizável ou não-utilizável com base nas somas de métricas para cada um dos blocos de canal.
