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, [ 6 ] with an extended version, Wi-Fi 6E , that adds the 6 GHz band. [ 7 ]
The Internet in Africa is limited by a lower penetration rate when compared to the rest of the world. Measurable parameters such as the number of ISP subscriptions, overall number of hosts, IXP-traffic, and overall available bandwidth are indicators that Africa is far behind the "digital divide".
Jawug, founded in 2002 [14] by Kieran Murphy, Justin Jonker, Ross Clarke and Steven Carter, was the first wireless user group in South Africa, starting as an experimental network between four students, then quickly expanding into a much larger network by interconnecting several separate wireless mesh networks.

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.
Many cities that previously deployed Wi-Fi based solutions, like Comcast and Charter Spectrum, are switching to municipal broadband. [2] [citation needed] Municipal fiber-to-the-home networks are becoming more prominent because of increased demand for modern audio and video applications, which are increasing bandwidth requirements by 40% per ...
