Icomera has conducted a successful trial of the world’s first 5G-enabled router on an X2000 train travelling on the Stockholm–Gothenburg route in Sweden.
The train is receiving over 1 gigabit of data per second using only commercially available 4G and 5G cellular networks: an industry-record-breaking level of throughput, surpassing the benchmark referred to in the public transport industry as ‘the Gigabit Train’.
Icomera has a strong track record when it comes to world firsts, having installed the first ever on-train Passenger Wi-Fi service, way back in 2003. At that time, megabit-level speeds were considered impressive and, seventeen years on, the onboard connectivity delivered in the current trial is over a thousand times faster. For context, the provision of ‘gigabit’ speeds is equivalent to passengers streaming over 10,000 songs or 200 HD films concurrently.
The onboard 5G technology trial, which began in October, involves fitting an X2000 train travelling on the Stockholm-Gothenburg route with Icomera’s X5 5G-enabled router, which houses four 5G radio modems. The results of the trial show delivery of over 1 Gbps of net throughput (data speed) to the train as it passes through telecommunications operator Tele2’s 5G cellular network in Stockholm’s central station, as well as other telecommunications operators’ LTE (4G) networks along the train route. The new Icomera system is also ready to use the 5G networks offered by all other cellular operators on the Stockholm-Gothenburg route, as they roll out.
The backwards-compatible 5G modems also yield gigabit speeds when using only 4G LTE networks thanks to ‘LTE CAT 20’ technology, which allows for faster data transfer by aggregating up to seven ‘frequency carriers’ at once. This indicates that transport operators upgrading to 5G-enabled technology ahead of the full 5G rollout should expect to see substantial increases in the throughput from existing networks, while establishing a future-proof means of delivering high-speed gigabit onboard Internet.
Icomera’s connectivity platform uses external antennas to connect to all available networks along the route. The data capacity from these networks is then aggregated by the onboard router and delivered directly to onboard systems via Ethernet, and to passengers via Wi-Fi. This method offers faster, more stable connectivity than having onboard devices connect directly to cellular networks along the route.
Mats Karlsson, CTO and SVP Innovation for Icomera, said: “Icomera is excited to demonstrate the technologies that will be used to deliver the true ‘Gigabit Train’. The trial presents an early look at the throughput achievable when using 5G-enabled hardware and cellular network aggregation technology, even before 5G rolls out. We look forward to furthering the digital future of public transport, delivering benefits for both transport operators and their passengers.”
