Abstract

"COMUNICAçõES EM UMA REDE SEM FIO ASSìNCRONA". Trata-se de sistema e técnicas para estabelecer uma referência que corresponda à temporização de um sinal recebido da primeira fonte, determinar a temporização para cada sinal recebido de uma pluralidade de segundas fontes, ajustar a referência à temporização do sinal recebido de uma das segundas fontes, a temporização do sinal recebido utilizada para ajustar a referência que está mais próxima no tempo da referência não-ajustada e sincronizar o sinal com a referência para transmissão. Enfatiza-se que este resumo é apresentado para conformar-se às regras que reqierem um resumo que permita que um buscador ou leitor verifique rapidamente o assunto da exposição técnica. Ele é submetido com o entendimento de que não será utilizado para interpretar ou limitar o escopo ou significado das reivindicações.
