Abstract

<B>SISTEMA E MéTODO PARA AJUSTAR A RADIAçãO DA ANTENA EM UMA REDE SEM FIO<D> Um método para definir radiação de antena em uma rede sem fio envolve direções variáveis de radiação de antena de antenas por toda uma faixa definida. Um receptor de teste mede os parâmetros de sinal proveniente das antenas em localizações de medição quando as direções de radiação de antena são variadas. O sistema de processamento determina uma direção resultante de radiação de antena para cada uma das antenas na rede sem fio, ou segmento da mesma, com base nos parâmetros de sinal medido.
