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.

WiFi 6 (802.11ax) introduces OFDMA (multi-user simultaneous transmission), BSS Coloring (interference reduction), and Target Wake Time (power management), significantly improving performance in dense industrial environments with many concurrent devices. In factories with 50+ wireless sensors, PLCs, barcode scanners, and tablets all connecting to the same access points, WiFi 6 reduces latency and improves reliability compared to WiFi 5.

WiFi is not suitable for hard real-time machine control (PLC scan times of 1 a 10ms) due to variable latency and potential packet loss. WiFi is appropriate for non-real-time industrial IoT: data collection from sensors, operator tablet SCADA access, remote monitoring, OTA firmware updates, and cloud connectivity. For real-time control, use wired industrial Ethernet (PROFINET, EtherNet/IP) or TSN-enabled wired networks.

5GHz WiFi is preferred for industrial environments, it provides more non-overlapping channels (less interference in dense deployments) and higher bandwidth than 2.4GHz. However, 5GHz has shorter range and higher attenuation through walls and metal structures. Deploy 5GHz access points at closer spacing in factories. WiFi 6E (6GHz band) offers even more spectrum but requires new hardware throughout the deployment.

Industrial WiFi networks should use WPA3 Enterprise with 802.1X authentication (individual device certificates rather than shared passwords), VLAN segmentation to separate OT (operational technology) devices from IT networks, intrusion detection systems, and network monitoring for unusual traffic patterns. Shared WPA2 PSK passwords are insufficient for industrial deployments where device compromise could affect production.

Yes, Avalue industrial PCs supplied by TSL Automation Solutions support WiFi 6 via M.2 wireless modules, available as factory-fitted options on selected models. Contact our Mumbai team for WiFi 6 configuration options and industrial wireless networking advice.
