In anticipation of 6 GHz being released for unlicensed Wi-Fi use, the Wi-Fi Alliance has introduced a new term to the industry, Wi-Fi 6E. The E stands for extended. This is aimed at providing a term to devices with 6 GHz support.
The FCC has not yet allowed 6 GHz for unlicensed use but there are companies performing their own internal lab tests.
6 GHz will provide 1200 MHz of spectrum for Wi-Fi use. The theoretical numbers the industry has been talking about has the potential to be realized. The 6 GHz spectrum would allow network operators to use up to 7x 160 MHz channel widths and 14x 80 MHz channel widths.
