Remember the good old days of wireless g, n, and ac? Well, they’re gone, replaced by Wi-Fi 4, 5, 6, and now 6E. Of course, much of this is mere rebranding. Under the new nomenclature, what was once rather clumsily known as 802.11g wireless networking is now known simply as Wi‐Fi 3. Similarly, 802.11n becomes Wi-Fi 4, 802.11ac is
renamed Wi-Fi 5, and 802.11ax is the latest Wi-Fi 6 standard.
But what of Wi-Fi 6E? In simple terms, it’s any Wi-Fi 6 device capable of operating in the 6GHz spectrum. In other words, 6E is simply 6 “extended” into the 6GHz spectrum.
That definition was made official in January this year when Wi-Fi 6E was certified by the Wi-Fi Alliance, the industry standards
body that oversees interoperability and backwards compatibility, and also ensures that Wi-Fi 6E supports the latest WPA 3 security features.
