Wi–Fi channel

The Wi-Fi 6 standard (aka 802.11ax) that was launched last year is much faster than the older Wi-Fi 5 (aka 802.11ac) that most of us are still using. However, Wi-Fi 5 and Wi-Fi 6 both use the same 2.4GHz and 5GHz bands to transmit Wi-Fi. The forthcoming Wi-Fi 6E adds a third band – 6GHz – and adds more channels too, for even greater speed.
