Abstract

"REDE SEM FIO, E, Nó DE REDE DE UMA REDE SEM FIO". A invenção se refere a uma rede sem fio com uma pluralidade de nós de rede, cada um dos quais consiste de pelo menos um aparelho elétrico e pelo menos um dispositivo de rádio que são arranjados para intercambiar dados através de um meio sem fio. Um nó de rede inclui um suprimento de relógio para suprir tanto aparelho elétrico quanto dispositivo de rádio com seu relógio. Um nó de rede que é designado como uma rede principal transmite, através de seu dispositivo de rádio, um padrão de sincronização que é dependente do relógio de seu suprimento de relógio. Todos os outros nós de rede, referidos como nós de rede secundários, são atribuídos para diferentes classes de distância hierarquicamente ordenadas dependendo de sua distância do nó de rede principal que é atribuído para a mais elevada classe de distância. Todos os nós de rede secundários de um classe de distância transmite, através de seu respectivo dispositivo de rádio, um padrão de sincronização que é dependente do relógio de seu respectivo suprimento de relógio e caracteriza a classe de distância. Um nó de rede secundário sincroniza seu suprimento de relógio por meio de pelo menos um padrão de sincronização recebido de uma classe de distância hierarquicamente mais elevada.
