Abstract

"SISTEMA, APARELHO E MéTODO DE COMUNICAçãO SEM FIO, E, PROGRAMA DE COMPUTADOR". Para resolver problemas que surgem quando um sistema de comunicação, como uma LAN sem fio, é construído como uma rede do tipo distribuída descentralizada, sem uma relação de estação de controle e estações controladas, como uma estação mestra e estações escravas, em um sistema de comunicação sem fio composto de uma pluralidade de estações de comunicação, sem uma relação de estação de controle e estações controladas, as respectivas estações de comunicação transmitem sinais-guia com informação referente a uma rede descrita sobre os mesmos, de uma para outra, para construir a rede, e torna-se possível fazer um julgamento sofisticado, como estados de comunicação de outras estações de comunicação, por esses sinais-guia.
