As smart factories integrate digital twins, AI inspection, and autonomous mobile robots (AGVs/AMRs), traditional industrial WiFi networks face severe bottlenecks in device density, latency, and roaming continuity. This article compares Industrial APs with 5G Industrial Routers, highlights the technical limits of Wireless LAN Controllers (WLCs), and explains why a 5G + WiFi hybrid architecture is becoming the mainstream choice for manufacturing.

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
