A Guide to Wi-Fi 6E – Wi-Fi 6 in the 6 GHz Band 2
1. Introduction
On April 23, 2020 the FCC voted unanimously to make 1,200 megahertz of spectrum available for unlicensed use in the 5.925-7.
125 GHz (6 GHz) band. This historic event was the culmination of several years of work by Wi-Fi advocates underscoring the FCC’s
commitment to promote unlicensed standards as the indispensable engine for wireless connectivity for American consumers.
The extension of Wi-Fi in the 6 GHz band, named Wi-Fi 6E by the Wi-Fi Alliance [1], has been strongly advocated for by many in the Wi-
Fi industry. From chipset and equipment manufacturers to service providers and end users, everyone agrees that m
