For fleet operators, transport OEMs, and systems integrators building solutions for connected vehicles and remote infrastructure, reliable connectivity isn’t just a feature—it’s a core requirement. The Teltonika ATRM50 is a router designed specifically for that context: high-speed, mobile, industrial-grade, and ready for the realities of deployment in transport environments.
It combines fast, low-latency 5G cellular with dual SIM support—including eSIM—housed in a compact but highly ruggedised unit that’s been engineered from the ground up for installation in vehicles, control cabinets, or exposed industrial locations.
Made for Vehicle Integration
Unlike generic industrial routers, the ATRM50 is built with transport deployment in mind. Its steel housing is IP67-rated for dust and water resistance, and it’s certified to withstand vibration, temperature extremes, and electrical noise typically found in vehicle environments.
Power input is wide-range (10–34 V DC), with built-in ignition sense—making it easy to integrate with vehicle electrical systems. Whether installed in trucks, buses, agricultural machinery, or even rail applications, the ATRM50 can boot and shut down with the engine or run continuously as needed.
Installation is flexible: the compact form factor (88 × 73 × 25 mm) and multiple mounting options (including DIN rail and panel mounting) allow it to fit into tight spaces, cabinets, or equipment bays.
5G Connectivity with Smart Failover
At the heart of the ATRM50 is a 5G modem capable of operating in both standalone (SA) and non-standalone (NSA) modes, with support for high-speed sub-6GHz bands. That gives you access to the bandwidth and low latency of next-gen networks, with fallbacks to 4G LTE or 3G if coverage drops—ensuring devices stay online regardless of location.
For critical applications—like vehicle telemetry, remote diagnostics, or mobile video—the router can use failover logic to switch between mobile networks. And thanks to its dual SIM slots, one of which supports eSIM (eUICC), you don’t need physical access to the device to switch carriers.
Built-in eSIM for Flexible Roaming and Remote Provisioning
With eSIM support, the ATRM50 is ready for modern SIM management workflows. That means:
- Profiles can be pushed remotely over the air.
- You can switch between carriers without touching the device.
- Global roaming becomes seamless and controlled—ideal for fleets operating across borders.
If your business already uses a global IoT SIM provider, integrating their platform with this device allows automated SIM provisioning, operator switching based on location or signal quality, and centralised control over data costs and usage.
Having both a physical SIM and eSIM slot also enables smart redundancy—for example, one SIM might serve as a backup network or kick in when crossing into a new region.
Hardware Interfaces and Expansion
Connectivity doesn’t stop at cellular. The ATRM50 includes:
- 2× Gigabit Ethernet ports – for LAN/WAN flexibility or connecting to local onboard systems.
- USB-C port – for diagnostics, updates, or tethered access.
- Mini-PCIe slot – allows hardware expansion such as custom wireless modules.
- GNSS support – GPS, GLONASS, Galileo, and BeiDou support with active antenna input for location-based services.
This combination of ports makes it easy to integrate the router into existing telematics platforms or extend functionality with additional modules.
RUTOS and RMS: Firmware and Remote Management
Like other devices in the Teltonika lineup, the ATRM50 runs on RUTOS, a hardened Linux-based OS with a full feature set:
- VPNs (OpenVPN, WireGuard, IPsec)
- Firewall and traffic shaping
- Captive portal support for Wi‑Fi applications
- SNMP, MQTT, Modbus for integration with telemetry and SCADA systems
It’s also fully compatible with Teltonika’s RMS platform, enabling remote provisioning, firmware updates, real-time monitoring, and SIM profile automation across large deployments.
For large fleets or distributed infrastructure, this kind of remote control significantly reduces installation time, downtime, and operational cost.
Certifications for Automotive and Industrial Use
This isn’t a router that just happens to be rugged—it’s been built to meet tough environmental and industry-specific standards:
- IP67 enclosure
- EN 50155 for rail applications
- ISO 7637-2 for vehicle power systems
- E-Mark certification for in-vehicle electronics
- EN 62368-1 safety compliance
Whether you’re supplying a national coach fleet, retrofitting smart city infrastructure, or rolling out telematics in construction machinery, the ATRM50 is built to comply from day one.
Use Cases That Make Sense
Fleet Management
The ATRM50 can collect real-time data from vehicle systems, transmit telemetry to the cloud, and host applications like driver behaviour monitoring or predictive maintenance—without relying on external modems or hotspots.
Dual SIM with eSIM is especially useful for fleets operating internationally. Operators can avoid roaming fees and downtime by switching networks based on geography or cost models.
Onboard Wi‑Fi and Infotainment
For passenger transport—buses, coaches, even boats—offering Wi‑Fi is a customer expectation. The ATRM50 can act as a mobile access point or gateway for third-party Wi‑Fi solutions. It’s compact enough to mount discreetly, and its high bandwidth 5G connectivity ensures smooth streaming, content access, or ticketing.
Remote Equipment and IoT Systems
In infrastructure or agriculture, you can deploy the ATRM50 as a standalone communications node. Power can come from vehicle systems or off-grid solar/battery setups. Its rugged build means it will survive exposed installations like fences, gates, pumps, or weather stations.
Rail and Roadside Installations
Thanks to its compliance with rail and roadside electronics standards, the ATRM50 is a suitable choice for embedded use in kiosks, terminals, roadside cabinets, or mobile surveillance units. It offers remote diagnostics, 24/7 uptime, and long-term operational stability.
