Wi-Fi 6 will extend to 6 GHz spectrum, in addition to existing 2.4 GHz and 5 GHz coverage, this new spectrum will be classified as Wi-Fi 6E and will initially be compatible with devices like smartphones and consumer routers. This is at least the theoretical next step in the Wi-Fi world, according to a press release from the Wi-Fi Alliance, though the organization notes that the 6GHz plan will be submitted for regulatory approval. The hope is that this "important part of unlicensed spectrum... will soon be available by regulators around the world", and after this official approval, Wi-Fi 6E devices will be available soon. As mentioned above, the original Wi-Fi 6E devices are expected to include consumer Wi-Fi access points and phones, and these will be followed by enterprise-grade access points. The Wi-Fi Alliance has also noted that it anticipates considerable adoption of Wi-Fi 6E in industrial settings, which would make it easier for remote maintenance or machine analysis. Also, Wi-Fi 6E should be used in both augmented and virtual reality for commercial and consumer devices. All of this, of course, assumes that the regulatory path is clear for the use of the 6GHz wireless spectrum.
Spectrum shortage
In general, the idea is to address the potential shortfall in Wi-Fi spectrum as more and more wireless devices come online, providing new bandwidth that will have less Interference with existing Wi-Fi 4 or 5 devices. The Wi-Fi Alliance notes: "6 GHz addresses the shortage of Wi-Fi spectrum by providing contiguous blocks of spectrum to accommodate an additional 14 80 MHz channels and 7 additional 160 MHz channels required for high bandwidth applications." band that faster data throughput such as high-definition video streaming and virtual reality.As has always been the case with Wi-Fi 6, the idea is not just faster speeds, but better performance in dense environments where there are many wireless devices (such as apartment buildings or public places) When Wi-Fi 6 was first released, more frequency bands are planned to be used in the future, as well as traditional 2.4 GHz and 5 GHz Wi-Fi: has clearly stated, so it's not surprising that this happens.One small quirk is that the purpose of introducing Wi-Fi 6 as the new name for the wireless standard formerly known as 802.11ax was to simplify the naming scheme and make it easier to to use (as well as previous Wi-Fi standards, which became Wi-Fi 5 and 4). So, announcing Wi-Fi 6E as a different variant goes against this goal in terms of introducing a potential point of confusion for less tech-savvy people.
