The next version, efficiently dubbed Wi-Fi 6, represents the new 802.11ax standard. For the average consumer, this means very little. I imagine some were able to glean improvement just by the increasing letters (and quantity of letters) but most didn’t care. Now, it’s obvious, version 6 is better than version 5 which is better than version 4, etc.
This new descriptive system is likely to make its way to just about everything that has Wi-Fi capability with the caveat that not all companies will adopt it at the same time. It is a no-brainer and definitely a welcome improvement.
