IEEE 802.11af, also referred to as White-Fi and Super Wi-Fi, [1] [2] is a wireless computer networking standard in the 802.11 family, that allows wireless local area network (WLAN) operation in TV white space spectrum in the VHF and UHF bands between 54 and 790 MHz. [3] The standard was approved in February 2014. [4]
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.
Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

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 ]
In a network conforming to 802.11k, if the AP having the strongest signal is loaded to its full capacity, a wireless device is connected to one of the underutilized APs. Even though the signal may be weaker, the overall throughput is greater because more efficient use is made of the network resources. [2]
Typical Generic Access Network services of this kind, such as Rogers Home Calling Zone (Rogers is an incumbent in the Canadian market), allow the caller to enter and leave the range of their home Wi-Fi network, and only pay GSM rates for the time they spend outside the range.
In 2018 The Wi-Fi Alliance created the simpler generation labels Wi-Fi 4 - 6 beginning with Wi-Fi 5, retroactively added Wi-Fi 4 and later added Wi-Fi 6 and Wi-Fi 6E. [23] [24] [25] Wi-Fi 5 had Wave 1 and Wave 2 phases. Wi-Fi 6E extends the 2.4/5 GHz range to 6 GHz, where licensed. Listed in historical and capacity order.
