Market overview

The market expects digital

Liberalization has opened up the EU passenger train market, adding to bus and air transport competition. In response, train operators must compete on more than just process, schedules, and routes; digitalizing their rolling stock to enhance their passengers’ experience and boost their own operational efficiency.

Customers today expect high-performance Wi-Fi connectivity, with passenger information systems and onboard ticketing to cut stress. For comfort, IoT devices control indoor air quality, temperature, and humidity.

Meanwhile, digitalization improves operator efficiency with high-reliability communications plus great network performance visibility, CCTV, physical and network access control, proactive onboard equipment maintenance, and GPS-based location tracking.

These goals demand better data connectivity. 4G/LTE ground to train communications are essential; 5G is far better if available. Satellite links are also important for route sections lacking cellular coverage, as are trackside links for stationary trains. Above all, all communications channels should be reliable, secure, and amenable to easy remote management.

On board, multi-service communications routers and gateways should support all train to ground links, and supply corporate-standard networks – including Wi-Fi access points for staff and passengers’ mobile devices, plus BT/BT LE connectivity for IoT devices and apps.

What are the important points related to Rolling Stock

  • Increase Operational Efficiency

    Operators can remotely configure, view, and control their rolling stock WAN environment – optimizing maintenance, managing physical and network security. AI can be applied to automatically collected data to help decision-making.

  • Enhance Passenger Experience

    Passengers, even in crowded carriages, can enjoy great Wi-Fi 6 connectivity. Passenger information systems and convenient online ticketing reduce stress, while IoT-based environmental management maintains onboard comfort.

  • Train to Ground Communications

    Multi-channel connectivity, using 4G/LTE, 5G, satellite and Wi-Fi are essential to ensure reliable, secure communications at all times – whether the train is in a remote location, halted at a station, or within a maintenance depot.

  • Onboard Communications

    Multi-WWAN routers distribute data throughout the train via dual Gigabit Ethernet cables to Access Points providing secure, high-speed Wi-Fi 6 to passenger devices in crowded carriages, and Bluetooth/BLE ports for IoT hardware.

Understanding Rolling Stock

Bandwidth, coverage, functionality

Competitive rolling stock digitalization calls for multi-WWAN links, security-ready and high-performance router, switching and AP hardware to achieve the bandwidth and coverage required, for all locations. But it takes advanced SD-WAN software components to optimize operational efficiency and deliver the passenger experience expected by today’s rail users.

Will 5G solve the railway dilemmas?

Every day we hear more news on 5G, its progress and evolution, as the demand for connectivity between vehicles, towns and cities, devices and sensors continues to grow. As you might expect, the railway sector and it’s train communications are no less affected, being one of the main players anxiously awaiting these new developments to adapt the 5G technology and use in their area of railway intra and intercommunication.

Wi-Fi 6 improves Passenger Experience on trains

Train communication systems are key to enhancing passenger experience and operator competitiveness, so it makes sense to use the best technologies available – and within the carriages, that includes access points that can deliver Wi-Fi 6 for passengers. Below, we look at the standard’s technical features, and then at how these translate into better transaction, information, and entertainment experiences on passengers’ devices.

Why 5G FWA can succeed.

IoT: Use cases and challenges

After several years in which the growth forecasts for the IoT market were not met, 2019 exceeded expectations, and certain market analysts predict connected devices will increase by 21% in 2020. We can therefore say that the broader adoption of this technology is finally taking place, and this mass adoption comes with several questions
