How 6G Mobile Networks Will Revolutionise the Rail Industries?

With 5G now fully rolled out, we’re already looking forward to the advent of 6G. By 2030, 6G will digitally interconnect people and objects in ways we couldn’t imagine even three years ago.

What are the opportunities for the rail industry? A glimpse into the future.

Wait, what about 5G?

You might have read about 5G being much more than a faster 4G. And that’s true. 5G offers three distinct advantages over 4G:

Ultra-high data rate, great for the transmission of high-resolution images and video
Low latency, indispensable for autonomous transportation
Quality of Service (QoS), the ability to ‘prioritise’ data: e.g.: safety data from the train are more important than Netflix movies for passengers

That already opens up a realm of possibilities for the rail industry right now. But by 2030…
6G: virtual networks

6G will be fundamentally different. It will create virtual networks, driven by the user’s needs. In other words: wherever there are multiple devices, a network will be created independently of technology. The devices will use whatever connection available – 5G, Wi-Fi, Bluetooth, satellite – to satisfy the user’s needs.

Thanks to the use of virtual networks, 6G offers a much stronger connection. If one connection technology is down or unavailable – e.g. wireless internet connection in remote areas – alternatives can be used.

6G networks will also be symmetrical, that is with equal download and upload speeds. Today, every network – even 5G – is still asymmetrical. It makes sense in a world where only humans connect to the internet: they consume more data than they produce. For Internet of Things applications (e.g. cameras on board a train), that’s no longer valid, however.

Opportunities for the rail industry

More (and better) real-time information

6G’s stronger connection opens the path to more real-time information, like video feed from multiple cameras. But video is only the beginning. With 6G, even real-time holography is possible.

Safety implications

6G will provide a much safer travel experience: AI-cameras can monitor the carriages for passenger aggression, for example. That way, security personnel can intervene quickly.

But 6G will also vastly improve the safety and scope of self-driving trains. Complete autonomy is not possible as of now, because network quality can’t be guaranteed everywhere. And an autonomous train that is not connected is not safe. 6G’s sophisticated QoS will always prioritise safety data.

No more wiring

Modern trains contain several kilometres of wiring. That’s expensive and also adds to the weight of the train. With 6G, we can do without a lot of that wiring: every data connection will we wireless. That’s cheaper and lighter, but also allows for more frequent refurbishments.

… and we’ve only just begun

6G is still in full development. By 2030 – the timeline for the advent of 6G – possibilities will have expanded beyond what we can image at the moment. But it’s already a promising, robust concept that will fundamentally change our technology. And that’s why we’re already looking into it.
