IN Brief:
- Kontron has opened a Düsseldorf production line for automotive and industrial 5G modules.
- Product development takes place in Berlin, with assembly and series manufacturing based in Germany.
- The modules will support industrial IoT, connected transport, critical infrastructure, and future FRMCS rail networks.
Kontron has opened a production line in Düsseldorf for automotive network-access devices and industrial M.2 5G communication modules, connecting its Berlin development operation with German series manufacturing.
The line will produce 5G automotive network-access devices alongside M.2 modules intended for embedded computers, gateways, routers, controllers, and edge systems. Initial application areas include smart factories, connected vehicles, energy infrastructure, medical equipment, industrial IoT, and communications used within critical services.
Automotive network-access devices provide the cellular link between a vehicle and external networks, while the M.2 form factor offers equipment developers a standardised route for adding cellular connectivity to an existing embedded platform. Integration still requires careful work around antennas, RF layout, thermal behaviour, firmware, carrier approval, cybersecurity, and product certification.
Development is undertaken at Kontron’s Berlin site, with industrial production at Düsseldorf, where approximately 120 employees work across 3,700 square metres of manufacturing space and 2,000 square metres of warehousing. The facility expects to produce around 15 million PCB assemblies and more than one million electronic control units during 2026.
Existing assembly volume gives the new line access to automated production equipment, process engineering, inspection, test, procurement, and quality systems already operating at industrial scale. Moving a radio design from engineering samples into repeatable production requires control of soldering, shielding, calibration, traceability, firmware loading, and end-of-line test rather than assembly alone.
Kontron is also targeting the Future Railway Mobile Communication System, or FRMCS, which is intended to replace GSM-R across Europe’s rail network. Based on 5G technologies, FRMCS will support operational voice, train control, data services, and future digital railway applications with greater capacity than the existing communications standard.
Rail electronics normally remain in service far longer than commercial communications products, creating tension between network evolution and fleet lifecycle. Modules must withstand temperature, vibration, electrical disturbance, and long maintenance intervals while remaining available through qualification, deployment, and subsequent replacement programmes.
Cybersecurity and software maintenance extend those obligations beyond the original hardware delivery. Cellular equipment may require vulnerability remediation, certificate management, network updates, configuration control, and support for evolving operator profiles throughout its service life.
European manufacturing gives Kontron closer control over firmware configuration, production changes, component traceability, and security-sensitive assembly. Shorter organisational links between engineering and the production line can also accelerate corrective action when component substitutions, radio certification, or field data require changes to a module.
The modules will nevertheless remain dependent on a global component base. Cellular basebands, RF front ends, memory, power-management devices, filters, oscillators, substrates, and production equipment are sourced through international supply chains, even where final development and manufacturing take place within Europe.
Control of design data, software, assembly, and validation offers a more realistic form of regional resilience than complete component independence. It gives manufacturers greater authority over configuration and lifecycle decisions while reducing dependence on finished communication modules produced and managed entirely outside the region.
Industrial connectivity is also becoming more heterogeneous. Private 5G, public carrier networks, Ethernet, time-sensitive networking, Wi-Fi, and legacy field systems will coexist across machinery and infrastructure, with gateways expected to translate between communications domains without compromising availability or security.
The arrival of Wi-Fi 7 in industrial gateway designs reflects the same architectural shift. Equipment increasingly requires several network technologies, selected according to coverage, latency, determinism, power consumption, spectrum availability, and the ownership model of the surrounding network.
Headline data rate is seldom the decisive factor in an industrial deployment. Antenna placement, handover behaviour, interference, network scheduling, power draw, environmental qualification, and the cost of maintaining operator approvals can determine whether a cellular interface remains reliable after installation.
Pre-integrated modules reduce part of that engineering burden by combining the modem, RF circuitry, power management, security functions, and software interface within a supported assembly. Standard form factors also make later replacement more practical, provided mechanical, thermal, and electrical compatibility are maintained across product generations.
Kontron expects the production capability to support later 6G systems, although the immediate challenge is to qualify the 5G modules across automotive, rail, industrial, and infrastructure programmes. Manufacturing scale, software support, radio approval, and long-term component continuity will determine how much of the Düsseldorf line’s projected capacity is converted into sustained deployments.
