Teltonika RUTX12
The RUTX12 is Teltonika's flagship dual-modem 4G router — two independent LTE Cat 6 modems in a single industrial chassis. Combined, they deliver up to 600 Mbps of cellular throughput and enable genuine simultaneous-dual-network operation: load-balancing across both modems in normal use, or instant failover if one carrier drops. Built for mission-critical links where one SIM isn't enough.

Best for
Mission-critical primary connectivity
Two carriers, one device. Run two SIMs from different networks in active/active load-balance to spread load, or active/standby for hot failover that's invisible to your application.
Live broadcast and media uplink
600 Mbps combined cellular is enough to backhaul a 4K stream with headroom. Pair with Cellular Private LAN to keep the production traffic off the public internet.
Retail and digital signage estates
No downtime when one operator has an outage — the second modem takes over in seconds. RutOS handles store-side networking and the SIMSY portal handles fleet visibility.
Site monitoring and SCADA
OT-grade hardware with two cellular paths. Wired LAN to your PLCs and sensors, both modems carry the upstream traffic.
