Abstract

"SISTEMA DE COMUNICAçãO DE DADOS DE PACOTE, MéTODO DE ESTABELECIMENTO DE COMUNICAçãO, E TERMINAL MóVEL". Um sistema de comunicação de dados de pacote inclui uma estação de controle e uma pluralidade de terminais móveis, que se comunicam, mediante demanda, com a estação de controle, por uma ligação sem fio. A estação de controle tem uma porta de dados, para a recepção de pacotes de dados destinados aos terminais, um arranjo para a geração de uma pluralidade de canais de dados, para transportar os pacotes de dados, e um arranjo para a atribuição dos pacotes de dados destinados a um terminal em particular a um ou mais dos canais de dados. Um canal de controle transporta a informação de controle referente aos canais de dados. Os canais são transmitidos para os terminais móveis como um sinal de r.f.. Os terminais têm um receptor, para a recepção do sinal de r.f., um conversor de analógico para digital, para a digitalização do sinal recebido, e um armazenador temporário, para o armazenamento do sinal recebido digitalizado. Os terminais monitoram, continuamente, o canal de controle, para extraírem informação de controle. O sinal armazenado é processado, para a extração dos dados de pacote destinados ao terminal, a partir de um ou mais dos canais de dados, em resposta à informação de controle recebida no canal de controle.
