Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks . 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 , with improvements for better performance in crowded places.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
IEEE 802.11ax is the successor to 802.11ac, marketed as Wi-Fi 6 (2.4 GHz and 5 GHz) [74] and Wi-Fi 6E (6 GHz) [75] by the Wi-Fi Alliance. It is also known as High Efficiency Wi-Fi, for the overall improvements to Wi-Fi 6 clients in dense environments. [76]

IEEE 802.11be, dubbed Extremely High Throughput (EHT), is a wireless networking standard in the IEEE 802.11 set of protocols [9] [10] which is designated Wi-Fi 7 by the Wi-Fi Alliance. [ 11 ] [ 12 ] [ 13 ] It has built upon 802.11ax , focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz ...
802.11ax WLAN is the first WLAN standard to use OFDMA to enable transmissions with multiple users simultaneously (it is called High Efficiency Multi Users [HE-MU] Access). In OFDMA, a symbol is constructed of subcarriers where the total number defines a Physical Layer PDU bandwidth. Each user is assigned different subsets of subcarriers to ...

The standard symbol guard interval used in IEEE 802.11 OFDM is 0.8 μs. To increase data rate, 802.11n added optional support for a 0.4 μs guard interval. This provides an 11% increase in data rate. To increase coverage area, IEEE 802.11ax (Wi-Fi 6) provides optional support for 0.8 μs, 1.6 μs, and 3.2 μs guard intervals. [citation needed]
