Industrial Wireless and Wi-Fi 6 for IIoT: What Manufacturers Need to Know

Why Industrial Wi-Fi Has Been Problematic

Traditional Wi-Fi (802.11a/b/g/n/ac) was designed for office environments — low device density, non-critical latency, and no hard real-time requirements. On a factory floor, wireless networks struggle with: RF interference from VFDs and motors; high device density (AGVs, tablets, sensors); and the latency spikes that occur during channel contention.

How Wi-Fi 6 Solves Industrial Problems

• OFDMA — allows multiple devices to share a single channel simultaneously, reducing contention in dense environments
• Target Wake Time (TWT) — schedules device communication windows, reducing collisions and saving battery life for IoT sensors
• BSS Colouring — reduces interference between overlapping networks by colour-coding frames
• Higher throughput — 9.6 Gbps theoretical peak vs 3.5 Gbps for Wi-Fi 5
• WPA3 security — improved encryption for OT network security

Industrial Wi-Fi 6 Use Cases

• AGV (Automated Guided Vehicle) fleet communication
• Handheld scanner and tablet connectivity in warehouses
• Wireless sensor networks for energy monitoring
• Mobile operator HMI panels on carts
• Remote monitoring of outdoor equipment

Many Avalue industrial embedded PCs and Panel PCs are available with Intel Wi-Fi 6 (AX201/AX211) modules or M.2 Wi-Fi card slots — contact TSL Automation to specify wireless connectivity for your embedded system.
