Since its inception, Wi-Fi has struggled with a lack of brand recognition. The IEEE (Institute of Electrical and Electronics Engineers) establishes the universal wireless networking standard and uses a cryptic numbering system.
This is the original Wi-Fi standard, which is referred to as 802.11, followed by the letters 802.11a, 802.11b, 802.11g, and so on. Engineers had to wrap their heads around the fact that 802.11ad isn’t an extension to 802.11a, but rather an amendment of its own.
This has always been a source of consternation for me (is ac really that much faster?). It’s finally been renamed by the Wi-Fi Alliance, the industry group that certifies and brands Wi-Fi.
We’re now using version numbers instead of letters. While there is no official Wi-Fi 1, 2, or 3, there are locations in Wi-history Fi’s where those versions can be found. These are the new names for the current six consumer standards.
|Outdated Title||New Title||Launched||Max. Velocity||Bands|
|802.11b||“Wi-Fi 1” (unofficial)||1999||11Mbps||2.4GHz|
|802.11a||“Wi-Fi 2” (unofficial)||1999||54Mbps||5GHz|
|802.11g||“Wi-Fi 3” (unofficial)||2003||54Mbps||2.4GHz|
|802.11n||Wi-Fi 4||2009||600Mbps||2.4GHz and 5GHz|
|802.11ax||Wi-Fi 6||2018/2019||10.53Gbps||2.4GHz and 5GHz|
In 2019, these new names are anticipated to gain traction, and by 2020, they will be widely used. Routers, laptops, and other Wi-Fi equipment will all use the new numbering system going forward.
The Wi-Fi Alliance wants device makers to utilize user interface icons to show the Wi-Fi level a device is connected to in order to encourage customers to upgrade their Wi-Fi equipment. You’ll see an icon warning you that you need to upgrade your devices if you receive a Wi-Fi 6 router but all of your devices are still on Wi-Fi 4.
What’s the big deal with Wi-Fi 6? In 2017, I penned an explanation of what was formerly known as 802.11ax. Details are correct except for the launch dates, which were too optimistic. In other words, 802.11ax is a game-changer in densely populated Wi-Fi hotspots where multiple networks coexist or where there are many concurrent users.
This summer, 802.11ax access points went on sale ahead of 2019’s planned formal certification. As of right now, no 802.11ax clients exist, but by the end of 2019, several mobile phones should support it.
Wi-Fi Alphabet Soup
The 802.11 standard comes in a variety of flavors, not just the well-known Wi-Fi flavors. There have been 802.11 working groups since the 1990s and the IEEE is now working on improvements to the Wi-Fi standard that won’t be in place for another two years. On the IEEE’s official timeline, you can see all of these changes in action. However, here’s a quick synopsis of what each one accomplishes and when it was approved.
