Hybrid Connectivity Solutions For Public Transport
While LEO satellite connectivity solutions provide an impressive level of capacity and availability on their own, aggregating satellite networks with cellular, trackside, and even other satellite networks as part of a “hybrid strategy” improves the overall capacity and reliability of the connectivity being supplied to the vehicle; filling coverage gaps and ensuring a more seamless experience overall.
Invented in 1999 and improved upon ever since, SureWAN™ is one of Icomera’s core proprietary technologies. Specifically designed for use on public transport, SureWAN empowers Icomera’s multi-modem mobile access routers to aggregate all available cellular capacity across multiple cellular modems in parallel, delivering the fastest, most reliable connection possible to the moving vehicle.
Using SureWAN in conjunction with Icomera’s satellite solution for rail, transport operators can aggregate and use all available communication links simultaneously, ensuring that the available capacity from multiple terrestrial cellular and multiple satellite networks is available for use by the onboard network.
The hybrid satellite connectivity solution is very simple and cost-effective to install or scale upOperators can easily add additional satellite antennas to new or existing Icomera installations. Satellite solutions are also fully supported by Icomera’s ICONIC monitoring and configuration tools.



Case Study: Deutsche Bahn
Gigabit Zug 2030
Icomera carried out a pioneering research project, ‘Gigabit Zug 2030’ (“Gigabit Train 2030” / GZ30), with its long-time client and partner, Deutsche Bahn. GZ-30’s principal aim was to develop and test innovative concepts for train-to-ground communications and onboard connectivity for passengers and connected devices on trains.

The GZ-30 trial carried out measurements using DB’s advanced TrainLab (aTL) (“the fastest lab on rails”), using railway lines across Germany as a testbed.
The GZ-30 research project was co-funded by Germany’s Federal Ministry of Transport and Digital Infrastructure (BMDV) through its Innovative Netztechnologien (InnoNT) Programme.
The tests took place on railway lines across Germany, evaluating important parameters such as total network throughput, coverage, latency, and connection stability over the entire route.
Gigabit Zug 2030: Methodology
Icomera and Deutsche Bahn installed 2 satellite antennas onto the vehicle and seamlessly aggregated satellite and cellular communication links using its SureWAN™ algorithm, supporting the hardware using its ICONIC network monitoring software suite.
After several weeks of vehicle modification in preparation for the trial, DB tested the performance of its onboard network under real-life drive-test conditions across the span of 7 weeks and a total of 15,000 km (around 9,320 miles).

Gigabit
The results of the trial were impressive.
Icomera demonstrated consistent availability and high throughput for the duration of the test. An average throughput of 784 Mbit/s was reached, along with a peak of 1.6 Gbit/s, delivering an exceptional level of capacity for onboard devices, systems, and passengers.
With only two satellite antennas installed, their throughput reached an average of 188 Mbit/s and 169 Mbit/s, respectively, accounting for nearly as much throughput as 10 cellular links could manage.
The GZ-30 trial demonstrated that a ‘Gigabit Train’ can become a reality within weeks, rather than years, underscoring the benefits of aggregating multiple technologies to address the challenges of modern rail. The ability to combine disparate sources of connectivity in real-time, even uncorrelated terrestrial and satellite networks, provides a powerful blueprint for digital trains of the future, even far beyond 2030.

Exploring the Frontiers of Connectivity:
Arctic Circle Connectivity Trial
Icomera recently partnered with Sweden’s KTH Royal Institute ofTechnology to test a combination of cellular and Low Earth Orbit (LEO) satellite connectivity in one of the most demanding environments for digital communications: the Arctic Circle. The study assessed how networks perform in remote northern regions, where sparse population density and limited infrastructure mean traditional cellular networks often struggle to provide adequate capacity. These challenges are not unique to Sweden. From Canada and Alaska to northern parts of the United Kingdom and the wider Nordic region, rural rail routes still experience gaps in coverage. With cellular networks alone unable to guarantee consistent performance across rural or isolated routes, LEO satellite solutions such as Starlink have become more than just a compelling possibility, but a virtual certainty.

At the time of testing, the Starlink constellation was less dense across Northern Latitudes. However, there are now far more Starlink satellites in orbit around the northern latitudes since the measurements took place, with the number set to increase even further in the coming months.

Arctic Trial Methodology
Travelling 970km from Umeå to Vilhelmina, the trial used an Icomera X5 router with only a single Starlink Flat High-Performance terminal alongside a commercial 5G setup to measure performance in both urban and remote conditions. With more than 50,000 Starlink and 23,000 cellular observations collected, the study delivered a detailed comparison of network coverage, throughput capacity, and availability in one of the world’s most challenging environments.
The Results
The results of the study highlighted the distinct advantages of combining uncorrelated networks, as well as the solid performance of satellite in sparsely populated regions:
Throughput Performance: Starlink demonstrated a significant advantage in median throughput, delivering speeds nearly ten times higher than the cellular network. This makes it a viable option for bandwidth-intensive applications such as real-time Digital Video Surveillance and highperformance Passenger Wi-Fi.
Connectivity Gaps: It was clear that despite the Arctic Circle being situated outside its main coverage area, Starlink still excelled in overall performance, offering a peak throughput of over 300 Mbit/s. Cellular networks provided more consistent baseline throughput but struggled to match Starlink’s bandwidth capabilities.
The Sky’s No Longer the Limit:
The Implications for Public Transport
Icomera’s demonstrations to date have shown that in real-word transport applications, simultaneously aggregating Starlink with terrestrial networks along the route offers highly improved overall network performance, which translates to more availability and capacity for onboard devices and applications, with fewer interruptions.
Given the attractive pricing of Starlink’s data plan and Icomera’s ability to design, install, and support the solution as part of its existing ecosystem, there has never been a better or easier time to benefit from all that LEO satellite connectivity has to offer.
