Remote antenna installation for a plurality of base stations sharing a single hf supply line for transmitting hf, control and monitoring signals and the supply direct voltage

The invention relates to an antenna transmission control device comprising a multiplexer circuit (11L, 111L; 11H, 111H) on the base station side or the antenna side. A protocol transmission for controlling components (17) close to the antenna is carried out alternately between the two multiplexer ci...

More Information
Summary:The invention relates to an antenna transmission control device comprising a multiplexer circuit (11L, 111L; 11H, 111H) on the base station side or the antenna side. A protocol transmission for controlling components (17) close to the antenna is carried out alternately between the two multiplexer circuits. The current-alerted or protocol-alerted signals created on the antenna-side ports (111'a) of the multiplexer (11H, 111H) provided on the antenna side can be measured or detected by the multiplexer circuits and injected into the transmission paths (5; 5a, 5b) together with a connection-dependent or consumer-dependent protocol.
