IEEE 原版 WiFi-6 802.11ax 协议规范，2021版本。 国际通信协会标准，最新版本，学习这一篇就足够了。

802.11ax，又称Wi-Fi 6，是IEEE 802.11推出的工作标准，是继802.11n之后第二个能够同时工作在2.4GHz与5GHz频段下的WiFi标准。其平均吞吐量能够比Wi-Fi 5（即802.11ac）提高至少4倍，并发用户数提升3倍以上，其速度能够达到600Mbit/s，是5G移动通信标准的有力竞争者。

IEEE 802.11ax wifi6标准_D8.0

IEEE 802.11ax-2019 will replace both IEEE802.11n-2009 and IEEE 802.11ac-2013 as the next high-throughput WLAN amendment. In this article, we review the expected future WLAN scenarios and use cases that justify the push for a new PHY/MAC IEEE 802.11 amendment. After that, we overview a set of new technical features that may be included in the IEEE 802.11ax-2019 amendment, and describe both their advantages and drawbacks. Finally, we discuss some of the network-level functionalities that are required to fully improve the user experience in next-generation WLANs and note their relation with other ongoing IEEE 802.11 amendments

The P802.11ax D8.0 was in the process of the second IEEE-SA recirculation ballot from November 3rd to 12th, 2020.
