What Is Wi-Fi 6? New Wi-Fi Names Explained

Must read

Wi-Fi has at all times had a little bit of a branding drawback. The ever-present wi-fi networking commonplace is ready by the IEEE (the Institute of Electrical and Electronics Engineers) and uses the engineers’ arcane numbering system.

The unique Wi-Fi commonplace was numbered 802.11, with speedier extensions getting letters on the finish: 802.11a, 802.11b, 802.11g, and 802.11n. Ultimately, with extra amendments to 802.11 than letters, the engineers began wrapping around: 802.11advert is not the fourth addition to 802.11a, however a modification of its personal.

In any case, that has been complicated (is ac sooner than n?), so lastly, the Wi-Fi Alliance trade group that handles Wi-Fi certification and branding—has rebranded the speeds for consumers.

We’re now swapping letters for model numbers. There isn’t a Wi-Fi 1, 2, or 3; formally, however, there are locations for these variations in Wi-Fi’s historical past. This is how the six present client requirements will get renamed.

You are prone to see these new names taking maintenance in 2019 and changing into widespread in 2020. You will see the brand’s unique numbering on routers, laptops, and different Wi-Fi gadgets going ahead.

The Wi-Fi Alliance will attempt to get gadget makers to push individuals towards newer Wi-Fi gadgets by having consumer interface icons present the Wi-Fi stage a tool is related to. So, when you get a Wi-Fi 6 router, however, all of your gadgets are on Wi-Fi 4, you may see an icon that reveals you’ll want to improve your devices to get higher speeds.

Why would you like Wi-Fi 6, anyway? I wrote an explainer on what was once 802.11ax again in 2017. The main points are nonetheless right, aside from the launch dates, which have been too optimistic. Briefly, 802.11ax improves efficiency in crowded Wi-Fi areas; there are many different networks or lots of people in your community.

802.11ax entry factors began hanging out there this summer season, forward of official certification, which is coming in 2019. There are not any 802.11ax shoppers but anticipate many 2019 cellphones to assist the usual.

The well-known types of Wi-Fi aren’t the one variations of the 802.11 commonplace. The IEEE has had working teams on 802.11 again to the 1990s, and it is at the moment engaged on amendments to the Wi-Fi commonplace that would not take impact earlier than 2022. You may see all these amendments on the IEEE’s official timeline. However, this is a fast rundown of what each does and when it was authorized.
