Built for the Road Ahead: The New ATRM50 5G Router

That’s where the ATRM50 comes in, Teltonika’s first 5G transportation router with M12 connectors, engineered for real-world mobility. With multiple certifications, cutting-edge cellular speeds, and design tailored for high-vibration, high-demand environments, it’s built to keep vehicles connected—whether it’s a city bus, a utility truck, or a train.

So, what exactly makes the ATRM50 stand out? Let’s explore how it goes beyond a typical 5G router.

ATRM50 in Focus: Design, Durability, and Always-On Connectivity

Reliable by Design

Most routers rely on RJ45 or barrel connectors—fine for office walls, but not for moving vehicles. The ATRM50 features four M12 X-coded Gigabit Ethernet ports and one M12 A-coded power input.

This ensures both data and power connections remain stable on the move. No more cables coming loose mid-route or power cuts that disrupt key systems. From onboard surveillance and ticketing to digital signage and diagnostics, the ATRM50 keeps everything securely connected and running smoothly.

Dual SIM and eSIM for Always-On Connectivity

Signal changes fast when you’re moving across neighborhoods, cities, and even borders. That’s why the ATRM50, includes dual SIM slots and an integrated eSIM with up to 7 profiles. It can automatically switch between carriers based on signal strength, network performance, or location, helping you avoid high roaming charges and reduce connectivity costs when traveling internationally.

Whether you're crossing country lines, passing through tunnels, or simply dealing with uneven cellular coverage, the router keeps everything online by switching to the best available connection—no user input required.

Ignition Detection and Low Battery Protection

Smart power management matters in vehicles. The ATRM50 includes ignition detection, allowing it to power on or off automatically with the vehicle—saving energy and extending component lifespan.

Meanwhile, low battery detection ensures the device receives a signal when the vehicle’s battery is running low, prompting it to shut down safely before full discharge.

Certified for Rail – Ready for More

While the ATRM50 is fully certified for railway use (EN 45545-2 and EN 50155), its rugged design goes far beyond the tracks. Built to endure fire, shock, extreme temperatures, and electromagnetic interference, this router is a reliable choice for any harsh and high-vibration environment—not just rail.

From bumpy roads and freezing winds to construction sites, wind turbines, and even mining or oil & gas operations, the ATRM50 stays firmly in place. Its robust housing and integrated mounting flanges ensure it keeps performing, no matter how tough the job site gets.

Speed That Moves With You

A reliable 5G router is essential for modern vehicles. Whether it’s streaming dashcam footage, uploading telematics, or providing fast Wi-Fi for passengers, today’s transport systems rely on high-speed, low-latency connectivity.

The ATRM50 delivers cellular speeds of up to 3.4 Gbps, ensuring real-time responsiveness for data-heavy services. It also works as a failover router with backup WAN, keeping the connection stable even when crossing borders or switching between carriers.

Whether you’re navigating city congestion or speeding down a rural highway, this router makes sure your cloud-connected applications don’t hit a dead zone.

Integrated GNSS for Real-Time Tracking

The ATRM50 comes with built-in GNSS for precise location tracking—ideal for route optimization, fleet coordination, and real-time updates to dispatch centers or passengers. Location data can be securely transmitted over 5G and monitored remotely via Teltonika’s RMS platform.

This makes it ideal for any vehicle where knowing its exact position improves service—be it a delivery van, a shuttle bus, or a long-distance train. Real-time location tracking also opens the door to smarter planning and incident response across entire fleets.

Centralized Control and Enhanced Security

Transportation fleets are constantly on the move and often spread across regions. Managing routers manually isn’t practical, which is why the ATRM50 supports Teltonika’s Remote Management System (RMS).

With RMS, you can push firmware updates, monitor performance, adjust settings, and troubleshoot remotely the entire fleet. For secure connectivity, the ATRM50 supports VPN functionality, allowing encrypted communication between vehicles and your central systems.

The ATRM50 also features a hardware-based Trusted Platform Module (TPM), which securely stores VPN credentials and private keys in a tamper-resistant chip. This adds an extra layer of protection, helping to keep fleet-wide connections reliable and secure.

REAL-WORLD APPLICATION: CONNECTIVITY IN MOTION

As European countries push to reduce carbon emissions, trains are becoming the preferred alternative to short-haul flights—especially on routes where rail travel offers a greener and nearly as fast option. But this shift brings new expectations. Passengers now demand real-time updates, onboard Wi-Fi, and seamless digital experiences, while operators rely on connected control systems to maintain performance and efficiency.

Yet rail environments pose serious technical challenges. From tunnels and cross-border transitions to multi-carriage train lengths and constant vibrations, ensuring stable connectivity in motion is no small feat. Traditional networking hardware often struggles to keep up—making robust, rail-ready infrastructure a necessity for the next generation of travel.

That’s where the ATRM50 steps in—not as a generic 5G router, but as a dedicated transport connectivity router with M12 connectors. In recent rail deployments, operators have used it to maintain seamless connectivity between carriages, stream live surveillance feeds to control centers, and coordinate fleet movements in real time—all without constant technician intervention.

The result? Fewer disruptions, smoother operations, and higher passenger satisfaction. And with remote management tools built in, scaling and supporting hundreds of onboard routers is no longer a logistical nightmare.
