Wi-Fi 6 impresses in Industry 4.0 trial’s first phase

The Wireless Broadband Alliance (WBA) has completed its phase one trial of Wi-Fi 6 infrastructure and services at the Mettis Aerospace factory in the UK.

Speeds of 700 Mbps using 80 MHz channels were achieved during the trial and low latency applications, like video calling and video streaming, performed well with the average latency being less than 6ms and the maximum observed latency was 11ms.

The WBA claims that these results prove that Wi-Fi 6 infrastructure can operate well in the presence of interference and noise in a complex and challenging factory environment while delivering high quality services for monitoring and maximising machinery performance, minimising downtime, and improving communications on the factory floor.

The phase I trial involved the following tests (among others), which were performed using devices such as smartphones, tablets, laptops and webcams equipped with the Broadcom BCM4375 and Intel AX200 Wi-Fi 6 chipsets::
