Abstract

os sistemas e método descritos aqui fornecem a comunicação sem fio eficiente em um sistema de conjunto em fase de onda milimétrica (mmw). o sistema pode compreender uma pluralidade de elementos de antena, cada um dentre a pluralidade de elementos de antena sendo configurado para ativar ou desativar os transceptores em resposta a uma saída de detector de energia indicando que um ou mais dos elementos de antena estão bloqueados. a desativação de determinados transceptores de elementos de antena bloqueados permite que os amplificadores de energia associados com os elementos de antena desbloqueados continuem a operar com eficiência máxima.
