Wi-Fi 6, how will the next Wi-Fi version change the concept of wireless networks?

The first Wi-Fi protocol was introduced in 1997. Over 21 years, it has been changed and updated many times with different standards and names, but most users only call them with one. The common name is Wi-Fi.

The organization oversees the adoption of new standards for Wi-Fi, the Wi-Fi Alliance (Wi-Fi Alliance) has continuously implemented new features and improved wireless network protocols. The next improvement of the wireless network protocol with many changes in speed, bandwidth and in particular is the name that will be applied next year.

Accordingly, the next Wi-Fi version will be called Wi-Fi 6, not the technical name as 802.11ab or 802.11n. It doesn't seem like a big problem, but it is a significant change for those who have tried to explain to others why they need to upgrade their routers and version 802.11ac is not the same as 802.11g. , or 802.11n, or 5GHz better than 2.4GHz .

With the change of name, users will now just need to remember that Wi-Fi 6 is newer and better than Wi-Fi 5, better than Wi-Fi 4 . Compared to complicated parameters, this concept It is easier to understand and simplify for general users even though each update will come with many different improvements.

Technically, Wi-Fi 6 refers to devices that support 802.11ax standards. 802.11ax is about 4 times faster than the current standard, 802.11ac helps to bring the maximum speed of 3.5 Gb / s along with improvements in performance. Thanks to the use of technologies such as 8x8 MU-MIMO, orthogonal frequency division modulation (OFDMA), add antennas to help performance in environments that need to serve multiple users. At a time like the stadium, the station . are more effective and consistent.

In addition, Wi-Fi 6 fixes the shortcomings of existing Wi-Fi networks such as congestion and interference. For example, with 802.11ac, if only a few users can receive actual traffic in excess of 300 Mb / s, but when the number of devices accessing is up to 10, then the bandwidth will be problematic. . And this difficulty will be solved by Wi-Fi 6.

In 2019, the device will officially appear on Wi-Fi 6 devices. But for smartphones and laptops to adopt Wi-Fi 6 standard as the default setting, it will need to be added. a few more years.
