Abstract

"DIRECIONAMENTO DE ANTENA PARA PONTO DE ACESSO COM BASE EM QUADROS DE CONTROLE". é fornecido um método de operação de ponto de acesso em uma rede de área local sem fio (wlan). O ponto de acesso inclui uma antena direcional para comunicação com pelo menos uma estação remota em link frontal com base em troca de dados de pacotes que compreende uma série de quadros de controle e um quadro de dados. A antena direcional inclui uma série de padrões de antenas. O método inclui o recebimento de primeiro quadro de controle através de primeiro padrão de antena da antena direcional da estação remota, transmissão de primeiro quadro de dados para a pelo menos uma estação remota e recebimento de segundo quadro de controle através de segundo padrão de antena da antena direcional da estação remota. São medidas a qualidade de sinal do primeiro quadro de controle recebido através do primeiro padrão de antena e a qualidade de sinal do segundo quadro de controle recebido através do segundo padrão de antena. As qualidades de sinal medidas correspondentes associadas aos primeiro e segundo padrões de antena são comparadas.
