Radio Solutions for Trains (TETRA)
TETRA radio systems are increasingly used for communication in public forms of local passenger transport. Here, special demands are placed an TETRA systems and their radio components, and in particular on the train equipment. Schnoor Industrieelektronik has mastered the challenge and has developed very different solutions for this field of application.
This solution comprises of a TETRA end device built into a 19" rack, connected to the passenger announcement system in the respective train as well as the operation via one operation and communication terminal from each driver's cab.
The seperation of the second operation terminal from the central unit takes place via a two-wire cable and can total several hundred metres.
The train driver has the choice of communication with the control centre or other participants of the radio system, a means of interconnection to the announcement system in the train. In the same way, it is possible to make announcements in the passenger compartments via the control centre.
