Sweden’s 6G Field Trials Are Under Way – What Will It Be Used For Once It Arrives?

Phones have only just got comfortable with 5G, and the telecoms industry has already moved on to the next number.

Every new generation arrives promising to change everything, and most of us notice it as slightly less buffering. So when Telia and Ericsson announced on 2 November that they’d started testing pre-standard 6G over the air in Sweden, using the upper 6 GHz band, the interesting part was what they’d be using it for.

Alongside the trials, the two companies signed a memorandum of understanding to work on 6G with industry, academia, startups and public-sector partners. Ericsson describes the tests as one of the Nordic region’s first over-the-air demonstrations of pre-standard 6G.

The early trials point to two uses: beefier uploads for AI applications and real-time video, and a network that doubles as a sensor.

Upload Speed Finally Gets Its Moment

Mobile networks have traditionally been built with downloading in mind, which suited a world of people streaming video and scrolling feeds.

AI applications and real-time video flip that around, because the data has to travel from the device to the network first. Ericsson says the upper 6 GHz band is intended to give networks wider channels, room for more traffic and a sturdier uplink.

The trials themselves measure coverage, signal performance, uplink capacity, reliability and latency, according to Telia’s release. Telia also lists self-driving transport, industrial robotics and monitoring of critical infrastructure as possible applications, with 6G combining connectivity, AI, distributed computing and sensing.

Those are the kinds of jobs where a delayed or dropped upload is a real problem.

When Cell Masts Become Radar Networks

The second early answer came from a separate demonstration. A separate demonstration used modified 5G radios to track multiple drones in real time, capturing location, velocity and elevation data. It’s an example of integrated sensing and communication, where the network carries data as usual and also works as a radar of sorts.

Ericsson treats the drone demo as separate from the 6G field trials, since it ran on 5G hardware, though it will support continued development and testing of pre-standard 6G capabilities. The appeal is quite easy to see. A network that can spot what’s flying overhead gives a second job to equipment that’s already carrying calls and data, which fits with the critical-infrastructure monitoring Telia mentions.

Don’t Cancel The 5G Contract Just Yet

According to Telia, partners in its NorthStar innovation programme should have access to initial 6G capabilities from 2029, with commercial rollout anticipated around 2030 to 2032. Ericsson’s own announcement gives no commercial date, and frames 6G as an evolution building on 5G Standalone, 5G Advanced, network APIs and AI-based automation.

That realistic tone is a handy antidote to the usual tech hype. Nothing here is a finished product, and the standard itself isn’t final, which is the whole point of pre-standard testing. The trials are built to produce real operational numbers, which gives engineering teams solid ground to stand on while the specifications are still being written.

The trials are built to produce hard performance numbers, which gives engineering teams something firm to work from while the specifications are still being written.

Startups Have A Seat At The Test Bench

The memorandum names startups alongside industry, academia and public-sector partners, and it covers national test environments including Digital Arena Sweden. Those are the places where early ideas for upload-heavy AI tools or network-based sensing could be tried out on real equipment before the standard settles.

Security is on the agenda from the start too. The partners will study security, resilience and energy efficiency, and Telia plans to convene stakeholders on a national 6G security architecture, with cybersecurity built in from the outset.

A network that carries sensitive data and watches the sky at the same time will have plenty to protect.

Sixth Time Lucky

Every generation of mobile gets remembered for one thing, and 6G hasn’t settled on its party trick yet.  Telia and Ericsson will assess future spectrum needs, including the 6 GHz and 600 MHz bands, which will influence how much room these ideas get once they leave the trial sites.

Over the next few years, the trials will show which of these ideas turn into products people pay for, and which stay in the demo room.
