The 6 GHz band is expected to be made available in unlicensed form soon and the Wi-Fi Alliance thinks it’s a good fit for Wi-Fi 6.

With the advent of 5G and the auction of other higher frequency bands for mobile, especially the mid 3 GHz bands, wifi has increasingly come into direct competition with cellular for bandwidth.
