Train coupling and keeping wireless connections up and running

What do you consider to be important characteristics for a wireless connection? Most people would answer that question with the need for a high data transfer rate and a stable, uninterrupted service available at all times. That of course are essential aspects of any connectivity challenge. But there is one more thing. Setting up the connection mustn’t be too difficult or complicated. That is particularly true in an environment where frequent changes in setup are necessary, for example in the field of trains. Westermo Neratec provides solutions that make train coupling and wireless setup easy.

Why train coupling and wireless connectivity must go hand in hand

The field of railways and trains is no exception to the rule that interconnectivity is a prerequisite to conducting business successfully. In cargo trains for example, technical devices are commonly installed to monitor the health of the load as well as the functionality of the carriage, ensuring secure transportation. But when trains are reordered and carriages are on the move in train coupling, the wireless connection to other parts of the train must go with them to ensure continued data transfer.

Train coupling: maintaining wireless connections is a safety feature

Unbeknownst to passengers aboard, the train they are sitting in transmits and receives signals all the time. It connects to stations and to traffic control units and to other trains on the track. Furthermore, there also inter-carriage links installed so that the engineer or central operations units can be alerted in case something goes wrong in one of the carriages. Most of these connections are an integral part of a train’s safety and security feature set. Thus, when train coupling, the wireless connections must be maintained and re-established seamlessly between all parts of the train.

Smart solutions for train coupling and the wireless connection setup

When you are a renowned expert in your field then it will be easy for you to come up with good ideas on how to master any challenges that might arise. That is certainly true for Westermo Neratec, the company that supplies railway companies around the world with wireless connectivity under the EN50155 802.11 standard. For train coupling situations, the wireless connections can be quickly and easily re-established using Westermo Neratec’s access points, bridges and switches that enable an automatic coupling or decoupling process and removes the need to use additional cables.

Train rolling or train coupling, the wireless connection stands

While the difficult task of train coupling and securing the wireless connection at the same time can be solved easily with technology developed for this specific situation, the connection must also be able to withstand a large number of other challenges when the train is in operation. Once rolling, all equipment installed is subject to the vibrations and shocks that come with the territory and that would often render wireless devices inoperable. Westermo Neratec’s products keep the connection strong at all times.
