Channels 1, 6, and 11įirst of all, let’s talk about 2.4GHz, because even in 2021, the majority of Wi-Fi installations still use the 2.4GHz band in some way. Rather than asking people to continue playing “Guess the relevant Wi-Fi standard,” somebody decided it would be easier to just call the current major consumer version “Wi-Fi 6.” There’s an even newer standard, Wi-Fi 6E, which supports signals in the 5-6GHz band, but the Wi-Fi 6E hardware in-market is a rather poor deal at present. If you’re wondering why we moved to branded naming as opposed to the standard number + a signifying letter combination, it’s because there are a lot more low-level updates and specification changes to 802.11 than there used to be. The fastest version of Wi-Fi currently available is branded as “Wi-Fi 6E,” aka 802.11ax-2021.
