Abstract

"MEDIçõES APRIMORADAS DE PERDA DE TRAJETO EM COMUNICAçõES SEM FIO". Método de determinação de necessidades de potência de link superior para um transceptor em sistema de comunicação sem fio inclui a obtenção de medições de um sinal farol que ocupa primeiro espaço de tempo em um quadro; obtenção de medições a partir de pelo menos um canal adicional que possui potência de sinal transmitido conhecida e que ocupa segundo espaço de tempo no quadro; e uso das medições para determinar estimativa de perda de trajeto.
