6 GHz freqency band
- [Instructor] For over two decades, Wi-Fi networks relied on the 2.4 gigahertz and five gigahertz frequency bands, as we discussed in our previous video. Then in 2021, an extension was added to Wi-Fi 6, which is also known as IEEE 802.11ax, and this extension was called Wi-Fi 6E, and it added support for the six gigahertz frequency band, which gives our wireless networks an additional 1,200 megahertz frequency range to use. In fact, if we were just using 20 megahertz channel widths, the six gigahertz band would support 59 non-overlapping channels. However, we typically bond multiple 20 megahertz channels together, which allows us to have more simultaneous communication streams. And with the six gigahertz band, if we used 160 megahertz channel widths, which we could get by bonding together eight 20 megahertz channels, we could have seven, non-overlapping 160 megahertz channels. Compare that to only two non-overlapping 160 megahertz channels that are supported by the five gigahertz…
