Abstract
"REDE DE COMUNICAçãO RF PARA COMUNICAR INFORMAçãO, E, MéTODO DE INICIALIZAçãO DE UMA SEçãO DE TRANSMISSãO DE DADOS DE ESPECTRO ESPALHADO DE SALTO DE FREQuêNCIA". é descrito um transceptor de espectro espalhado de baixa potência capaz de preservar a energia, enquanto inicializa seletivamente transmissões de dados num protocolo de espectro espalhado preferido. O transceptor, enquanto em um modo de suspensão profunda para conservação de energia, usa um conjunto de circuitos DSSS para monitorar periodicamente a freq³ência da largura de banda predeterminada por um código de espalhamento de um sinal DSSS proveniente de uma unidade receptora remota (20). Com o recebimento do sinal de espalhamento apropriado, uma transmissão de dados limitada é iniciada. O sinal DSSS contém informação que pode ser decodificada e utilizada para sair do modo de recebimento DSSS e para entrar no modo de comunicação/transmissão FHSS, ou uma seção FHSS pode ser iniciada automaticamente com o recebimento de um sinal de despertar adequado. Enquanto no modo FHSS, os dados codificados FHSS no transceptor do dispositivo de ponto extremo (10) se comunicam com a unidade receptora remota (20). Depois de completar a transferência de dados, o transceptor retorna para o modo de suspensão profunda de baixa potência e recomeça o monitoramento DSSS.
