Abstract

"MéTODO DE TRANSMISSãO DE DADOS DE UM SISTEMA DE LIGAçãO DE RáDIO, E, SISTEMA DE LIGAçãO DE RáDIO". Esta invenção relaciona-se a transmissão de dados em um sistema de ligação de microondas particularmente por conexões de ponto a multiponto. O arranjo de acordo com a invenção utiliza ambos arranjos duplex de divisão de freq³ência e tempo para simplificar estruturas de subestação. De acordo com a invenção, uma subestação transmite em momentos diferentes do que recebe, e usa freq³ências diferentes para a transmissão e recepção. A estação central, por sua vez, inclui uma unidade de duplexador, por meio de que ela pode ambos transmitir e receber simultaneamente quando as freq³ências de transmissão e recepção estão separadas suficientemente. Tal arranjo alcança vantagens do arranjo duplex por divisão de tempo, tal como por exemplo uma estrutura de subestação barata, sem as desvantagens relacionadas ao arranjo duplex por divisão de tempo.
