Wireless Standards Wi Fi 6 Evolution and Wi Fi 7

IEEE standardized wireless technologies as 802.11, 802.11a b g n, 802.11ac. 802.11 legacy was released by IEEE in 1997. IEEE 802.11b was made available to users through Wi Fi routers. With 802.11g n increased the network capacity and data throughput support. 802.11n or Wi Fi 4 introduced MIMO technology. Downlink MU MIMO was one of the main features of 802.11ac or Wi Fi 5. The latest 802.11ax or Wi Fi 6 supports both downlink and uplink MU MIMO. The use of OFDMA, dual bands, Target Wake Time technologies will help in handling traffic offloaded from the 5G wireless network and help in catering to dynamic network needs, handling massive dense IoT networks, and high throughput demands. Wi Fi Alliance started working on the next wireless generation that is IEEE 802.11be or Wi Fi 7. Wi Fi 7 will be standardized by 2023.
