Wired Solution
Inter-vehicle systems must satisfy stringent demands, since the cables in motion are subjected to a wide range of different mechanical stresses. These are caused especially by vibration, bending and torsion in addition to occasionally extreme operating conditions and environmental influences.
System cables are manufactured on the basis of specific customer needs, taking into account the proven HUBER+SUHNER design guidelines. Manufacturing is fairly time-consuming because the cables pass through several in-line process operations. The earlier HUBER+SUHNER is familiarised with concrete projects, the easier it will be to satisfy the relevant customer needs.
As a system provider, HUBER+SUHNER offers professional consulting as early as during the development phase. In order to produce optimal cable design solutions, it makes sense in the project engineering phase to allow the widest possible latitude in terms of how the cores and elements are to be combined in the cables.
Wireless Solution
Data can be transmitted between carriages using antennas rather than cables. This means lower installation and maintenance costs, particularly for retrofitting. Less effort is also required to couple and uncouple the carriage.
The signal is often transmitted from carriage to carriage using Wi-Fi standard 802.11 a/n in the 5 GHz frequency band. This is mainly done to avoid problems between the various communication standards within a train. MIMO antennas also allow larger data volumes to be transmitted.
