In a previous article I was writing about what is Wi-Fi 6 and show what are the advantages of one router with this new 802.11ax standard.
As I mentioned in that article, Wi-Fi 6 uses all 2,4 GHz and 5 GHz bands, just like the old standard Wi-Fi 5 (802.11ac). The big difference between the two standards is the division of a wireless frequency channel into several dedicated channels using the technique Orthogonal Frequency-Division Multiple Access (OFDMA), which means that each user connected to a Wi-Fi 6 compatible device will benefit from a dedicated bandwidth, thus avoiding network congestion.
Many users are confused about the standard version name and wireless bandwidth. Wi-Fi 6 uses 2.4GHz and 5GHz free bands, while licensing for 6 GHz Band is still waiting. This frequency is currently regulated, and until US Federal Communications Commission will not agree that it be freely used globally, this will not happen. Currently there is no router on the market capable of supporting 6 GHz Band.
Wi-Fi Alliance (the organization that manages and develops Wi-Fi) says that Wi-Fi routers 6 which will be able to support the 6GHz spectrum will be rated with the standard Wi-Fi 6E.
What will bring the new 6GHz band on 6E Wi-Fi routers
On the 6GHz spectrum there will be sufficient bandwidth for 7 160MHz channels si 14 40MHz channels, as the saying goes Wi-Fi Alliance. Besides the ability to support a greater number of users simultaneously in very crowded spaces, this wider spectrum will increase performance for applications that use high bandwidth, such as high quality live video transmissions si virtual reality applications / augmented reality.
Routers marked with Wi-Fi 6E are expected to appear on markets around the world once the regulatory agreement is approved globally and no license for the 6GHZ spectrum will be required. This 6GHz spectrum is currently only used in research and scientific environments.
How much is a 6E Wi-Fi router required?
Certainly wireless technology will advance even more than it is today. We have routers on the market, several models of laptops and smartphones / iPhones that support Wi-Fi 6, but this technology will not necessarily bring a higher internet browsing speed, but a stable connection with dedicated bandwidth per user in crowded spaces. For a "home user" this technology is not financially worth it at the moment. Wi-Fi 5 (802.11ac / 5GHz and 2.4GHz) is enough.
As for WiFi 6E, this 6GHz spectrum will be more useful in the industry. It will allow the development of applications with more generous bandwidth and will be able to manage several simultaneous connections to the same device.
