Summary

This talk is partitioned into 4 sections. It starts with a comprehensive Wi-Fi 6 introduction. Also known as high-efficiency Wi-Fi, for the overall improvements targetting dense environments, the former IEEE 802.11ax standard has been ratified early last year. The first part introduces its main concepts which amongst others go by abbreviations like OFDMA, 1024-QAM, 160 MHz channels, MU-MIMO, TWT, and WPA3. Wi-Fi 6E enabling operation of features in the unlicensed 6 GHz band is also covered. The second part looks at the Wi-Fi 6 OpenWrt AP/router landscape. The only officially supported devices are all based on the MediaTek MT7915E chipset while supporting promising Qualcomm IPQ807x resp. Qualcomm QCN5054/QCN9024 based devices is still a work in progress. Wi-Fi 6 clients are covered in the third part with the pre-dominant Intel AX200/201/210 cards, MediaTek MT7921K Wi-Fi 6E, and Qualcomm QCA6391 based clients all running mainline Linux, of course. The last part concludes with a discussion of various real-life configurations and benchmark demo use cases.
