You can see all these amendments on the IEEE's official timeline (Opens in a new window). The IEEE has had working groups on 802.11 back to the 1990s, and it's currently working on amendments to the Wi-Fi standard that wouldn't take effect before 2022. The well-known forms of Wi-Fi aren't the only versions of the 802.11 standard. There are no 802.11ax clients yet, but expect many 2019 mobile phones to support the standard. In short, 802.11ax really improves performance in crowded Wi-Fi areas, where there are a lot of different networks or a lot of people on your network.Ĩ02.11ax access points started becoming available this summer, ahead of official certification, which is coming in 2019. The details are still correct, except for the launch dates, which were too optimistic. Why do you want Wi-Fi 6, anyway? I wrote an explainer on what was once 802.11ax back in 2017. So, if you get a Wi-Fi 6 router but all your devices are on Wi-Fi 4, you'll see an icon that clearly shows you need to upgrade your devices to get better speeds. The Wi-Fi Alliance will try to get device makers to push people toward newer Wi-Fi devices by having user interface icons show the Wi-Fi level a device is connected to. You'll see the new numbering on routers, laptops, and other Wi-Fi devices going forward. You're likely to see these new names taking hold in 2019 and really becoming widespread in 2020.
