Arrangement for transmitting security-relevant data over radio path has second antenna and redundant evaluation device per station with both antennae being connected to transmitter and/or receiver

摘要

The arrangement has a transmitter (18,20) and a receiver (22,24) per station (14,16) with an antenna (30,32), an evaluation device (38,40) and a changeover device (26,28) for connecting the antenna to the transmitter and/or receiver. Each station has a second antenna (34,36) and a redundant evaluation device (42,44). Both antennas are connected to the transmitter and./or receiver, which are associated with the first and/or second evaluation unit. Independent claims are also included for the transmission of a security-relevant data over a radio path.
