    ^A In the 2.4 GHz bands bonded 40 MHz channels are uniquely named by the primary and secondary 20 MHz channels, e.g. 9+13. In the 5 GHz bands they are denoted by the center of the wider band and the primary 20 MHz channel e.g. 42[40] ^B In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions.

    Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...

    They do not exist in the official nomenclature. [6][7][8] IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [c] The standard has been retroactively labelled as Wi-Fi ...

    Dynamic frequency selection. Interference by 5 GHz Wi-Fi seen on Doppler weather radar. Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military ...

    802.11a uses the 5 GHz U-NII band which, for much of the world, offers at least 23 non-overlapping, 20-MHz-wide channels. This is an advantage over the 2.4-GHz, ISM-frequency band, which offers only three non-overlapping, 20-MHz-wide channels where other adjacent channels overlap (see: list of WLAN channels). Better or worse performance with ...

    en.wikipedia.org/wiki/Wi-Fi_6

    Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks (WLANs). It operates in the 2.4 GHz and 5 GHz bands, [9] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [10] It is an upgrade from Wi-Fi 5 (802.11ac), with improvements for better performance in crowded places.
