Abstract
"SISTEMA DE COMUNICAçõES DISTRIBUìDAS POR PACOTE DE DADOS RADIOFÈNICOS". Trata-se de um sistema de comunicações distribuídas por pacote de dados radiofónicos, compreendendo: - uma estação de controle, e uma pluralidade de terminais remotos amplamente dispersos, estes últimos tendo um modo ativo, durante o qual são capazes de receber e transmitir pacote de dados, e um modo de repouso, durante o qual ficam inativos, dita estação de controle e cada um dos terminais remotos sendo capazes de atrair comunicações em pacote de dados, através da ligação de direção TDM de dita estação de controle para ditos terminais, e uma ligação de retorno ao acesso múltiplo acanalado dos ditos terminais para dita estação de controle; - cada terminal remoto tendo um endereço e sendo pré-assinado por tempos específicos na ligação de direção, durante o que pode ser enviado pela dita estação de controle, e cada terminal incluindo um controlador de tempo operável em dito modo de repouso, fazendo com que dito terminal entre periodicamente no modo ativo, durante seu tempo pré-assinado, e um processador para identificar pacotes recebidos através da ligação de direção; e dita estação de controle incluindo um dado base para armazenar os tempos assinados para vários terminais remotos, meios de transmissão em demanda, pacotes de dados enviados a terminais específicos em seus tempos assinados na ligação de direção e meios para receber dados dos terminais em espaços de tempo na ligação de retorno acanalado.
