Wi-Fi 6, or IEEE 802.11ax, was certified by the Wi-Fi Alliance in the fall of 2019, and unlike past upgrades, this generation highlighted efficiency by introducing multi-user concepts, rather than focusing solely on faster speeds and bigger channels. Then, the Federal Communications Commission (FCC) made Wi-Fi even more powerful by opening up the 6 GHz band (5925-7125 MHz) for Wi-Fi use, a capability known as Wi-Fi 6E. With this decision, the Federal Communications Commission (FCC) made an additional 1,200 megahertz of spectrum available for unlicensed Wi-Fi use, and according to most industry experts, it was the biggest thing to happen to Wi-Fi in the last decade.
