Why Connectivity on the Move Matters
Modern transportation isn’t just about moving from point A to B – it’s increasingly about staying connected on the go. Passengers expect Wi-Fi for entertainment and real-time updates, while fleet operators rely on data links for telematics, surveillance, and system monitoring. Delivering reliable internet in motion is challenging due to constant vibration, harsh conditions, and cross-border network changes. This is the problem that the Teltonika ATRM50 router is built to solve.
ATRM50 is a 5G cellular router designed specifically for transportation environments. It combines high-speed mobile connectivity with a ruggedised form factor to keep vehicles and rolling stock online at all times. Featuring industrial-grade M12 connectors, ultra-fast 5G speeds (up to 3.4 Gbps), dual SIM and eSIM support, and full railway certifications, the ATRM50 is built for serious deployment across rail, road, logistics, and industrial IoT networks.
