NEC Display's Led technology transforms the passenger experience at Arlanda Airport

The largest airport in Sweden has solved the problem with interference caused by Led technology, thanks to NEC Display solutions.

The giant Led screens of NEC Display Solutions Europe installed at Arlanda Airport (Stockholm), the largest in Sweden, have transformed the experience of passengers passing through their terminal, that have real-time flight information and commercial content of interest in your trip.

The project has been especially relevant for this manufacturer of visual systems, since one of the objectives was to minimize electromagnetic interference associated with Led technology, which can cause serious problems in passenger terminals.

Swedavia, The company that owns the ten most important airports in Sweden commissioned NEC Display to supply large-format Led screens to locate them in the check-in and baggage claim areas, so that passengers can consult information and updates about their flights, advertising, Promotions and other content.

These Led screens, with sizes of 44 and 15 square meters, They manage to capture the attention of passengers while keeping them informed, and also provide new revenue and advertising opportunities.

For the development of this project, one of the fundamental requirements of Swedavia was that all Led screens, not just the individual modules, meet EMC Class B standards (Electromagnetic compatibility), so that they do not cause any interference with other systems and devices present in the terminal or at any other point in the airport.

This is how Johan Monie explains it, Head of Passenger Processing at Swedavia, "In the beginning,, we saw another project with Led technology, But during the testing phase we discovered that the screens caused interference with other equipment.. Led technology emits electromagnetic radiation, and they would have caused us serious problems with WiFi and Bluetooth connectivity, generating a negative passenger experience, which is precisely what we wanted to avoid. That's why we turned to our partner NEC Display to find a solution and answer the problem.".

specifically, NEC Display designed two direct vision Led screens, 3.91mm, with special shielding to emit minimal levels of electromagnetic radiation. This manufacturer has been responsible for all aspects of the project, from the design of the modules, of power supply and data, of manufacturing, The installation and commissioning of the screens.

This company has also provided a backend platform that allows Arlanda Airport to collect and manage content from multiple sources for Led screens installed in a single application..

After successfully passing a strict testing period, in which both Led screens exceeded without problems the criteria of EMC, the project was unveiled last month and is currently in operation at this Stockholm airport facility..

"More and more transport centers opt for Led technology for their screens, but they may not be fully aware of the impact they have on other communication systems," stresses Richard Wilks., Airport and Public Transport Business Development Manager, NEC Display Solutions Europe.

In this sense and, unless properly designed, "These screens can compromise the connectivity passengers expect to have when traveling., such as WiFi, Bluetooth technology and 4G and 5G networks. They can also interfere with safety systems that work under radio frequency., such as employee walkie-talkies or radar and air-to-ground communications", assures this manager.

Transportation hubs, such as airports, are getting louder, with numerous signs and huge volumes of human traffic, "That is why we have decided to bet on NEC Display to also change all our LCD screens and comply with EMC Class B”, Wilks advances.

For this manager, “transport hub operators want to take advantage of the Led, But they must be aware of the impact these screens have on other technologies and require their technology partners to provide them with solutions designed to avoid any inconvenience or interference.".
