Abstract

"MéTODO E APARELHO PARA COMUNICAçãO SINCRONIZADA SOBRE ARRANJO BáSICO SEM FIO". Comunicação sem fio é provido por meio de uma pluralidade de repetidores (12-18) que são sincronizados por comunicação com um repetidor controlador central (11) . os repetidores (11-18) constituem uma rede básica sem fio (100) onde pulso de freq³ência é utilizado para automaticamente estabilizar sincronização apesar de trocas dinâmicas na rede sem fio (100) Um repetidor (12-18) introduzido na rede automaticamente esquadrinha para e sincroniza para outro repetidor (12-18), enquanto continua ao mesmo tempo percebendo outros sinais do repetidor (200) identificando o repetidor controlador (11) ou outro repetidor (12-18) fechamento para o repetidor controlador (11), de modo que para comunicar com o repetidor controlador (11) através de uma conexão de comunicação mais direta (19).
