80211acnax

80211acnax is not a recognized or standard Wi-Fi protocol designation. The Wi-Fi Alliance, which certifies Wi-Fi products, uses specific names for its standards. The current generation of Wi-Fi, known for its speed and efficiency enhancements, is officially designated as Wi-Fi 6 (based on the IEEE 802.11ax standard). Prior to Wi-Fi 6, the standard was Wi-Fi 5 (based on IEEE 802.11ac), and before that, Wi-Fi 4 (based on IEEE 802.11n).

It's possible that "80211acnax" is a misremembered or typographical error combining elements of different standards. IEEE 802.11ac introduced significant improvements over its predecessor, primarily in the 5 GHz band, focusing on higher throughput through techniques like wider channels and advanced modulation. IEEE 802.11ax, now known as Wi-Fi 6, builds upon the advancements of 802.11ac by focusing on increased efficiency and performance in dense environments, even at lower speeds. It achieves this through technologies like OFDMA (Orthogonal Frequency Division Multiple Access) and MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) in both 2.4 GHz and 5 GHz bands, as well as an optional 6 GHz band with Wi-Fi 6E.

Therefore, any reference to "80211acnax" likely refers to either the 802.11ac standard, the 802.11ax standard (Wi-Fi 6), or potentially a combination of features intended to represent an advancement beyond 802.11ac but not yet aligned with the official 802.11ax naming convention. For accurate information on current Wi-Fi technology, it is recommended to refer to the official designations like Wi-Fi 6 and its underlying IEEE 802.11ax standard.
