Abstract

Patente de Invenção: <B>"ESTAçãO DE BASE DE RáDIO MóVEL COM ANTENA ADAPTáVEL"<D>. Uma estação de base de rádio móvel, com um transmissor (TRX) para cada freq³ência de transmissão, bem como com vários receptores (RX 1, RX 2, RX 3, RX 0), sendo que as saídas de antenas individuais (AN 1, AN 2, AN 3) ou de uma rede de matriz (BUM), bem como de pelo menos uma antena onidirecional (AN 0), estão unidos com desvios de transmissão/recepção (SE 1, SE 2, SE 3, SE 0) e os ramais de recepção dos desvios estão guiados para os receptores individuais (RX 1, RX 2, RX 3, RX 0), os ramais de transmissão dos desvios estão unidos seletivamente, através de um dispositivo de ligação (SWI) controlado, com a saída de um transmissor (TRX) e, para processamento dos sinais de saída do receptor, está previsto um detector (DET) comum, que está configurado para fornecer, através de um comando de antena (AST), ao dispositivo de ligação um sinal de comando (stw) de um tipo tal que o transmissor seja unido com uma antena determinada no detector (DET).
