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.

As Industry 4.0 matures, traditional wired networks often struggle to meet the high demands of modern infrastructure. 5G Industrial Routers and CPE have emerged as the "neural centers" of the Industrial IoT, offering high reliability, low latency, and flexible deployment. These intelligent terminals combine 5G cellular modules, Wi-Fi routing, and industrial gateways, supporting critical features such as dual-SIM redundancy, rugged environmental adaptation.
