Your bus is mid-route, the signal drops, and your passenger Wi-Fi goes dark. Or your rail cab needs a router that won't rattle loose after 200,000 kilometres of vibration. The ATRM50 was built for exactly that. Four M12 Gigabit Ethernet ports lock in with hex-key security so nothing backs out at speed. M12 power input means no loose barrel plug in a moving vehicle. You get up to 3.4 Gbps cellular throughput, and when one carrier bails, the dual SIM and eSIM failover picks up the load without your passengers noticing. It's certified to EN 45545-2 and EN 50155, so it meets the safety bar for railway environments and holds up in other demanding transport settings. Built-in GNSS keeps your location data accurate, the integrated mounting bracket means you're not sourcing a separate bracket, and RMS compatibility lets your fleet team manage the whole thing remotely. In the box: the router, a hex key, a quick-start guide, and the packaging. No fumbling for an adapter at 6am before the first shift
