As SCADA systems evolve from isolated architectures toward open, cloud-based Industrial IoT (IIoT) environments, the "neural system"—the communication network—becomes critical. Industrial routers serve as the essential bridge, connecting remote RTUs and PLCs to central control hubs via secure 4G/5G VPN tunnels.

Traditional MPLS dedicated lines are being challenged by the agility of 5G. This guide explores how industrial 5G routers—like the WR575, WR578, and the dual-module WR677-D—provide zero-touch deployment and ultra-reliable connectivity. Learn how to design robust enterprise architectures that integrate high-speed cellular links as primary connections for retail, smart manufacturing, and remote branch offices.

WRTOS (Wavetel Router Operating System) is a highly optimized, Linux-based embedded OS designed specifically for the rigorous demands of Industrial IoT. Unlike consumer-grade software, WRTOS prioritizes stability and security through modular design, dual hardware/software watchdogs, and comprehensive multi-link redundancy. With native support for 10 VPN protocols and industrial standards like Modbus and MQTT, it bridges the gap between field-level OT data and IT cloud platfor
