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 ...
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [ 1 ]
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.
The name Wi-Fi is not short-form for 'Wireless Fidelity', [34] although the Wi-Fi Alliance did use the advertising slogan "The Standard for Wireless Fidelity" for a short time after the brand name was created, [31] [33] [35] and the Wi-Fi Alliance was also called the "Wireless Fidelity Alliance Inc." in some publications.

Hotspot 2.0, also known as HS2 and Wi-Fi Certified Passpoint, [24] is an approach to public access Wi-Fi by the Wi-Fi Alliance. The idea is for mobile devices to automatically join a Wi-Fi subscriber service whenever the user enters a Hotspot 2.0 area, in order to provide better bandwidth and services-on-demand to end-users and relieve carrier ...
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 ]
