Starting with the next generation of WiFi devices, WiFi will finally have a comprehensible naming scheme. In the past, different versions of wifi went by various letters, that were hard to keep track of even if you were in the industry. 802.11, 802.11a, 802.11b, 802.11g and so on up to 802.11ay. Each version works with the last version but unless you memorized all the versions it was hard to know which was which.
Now, WiFi will go by simple numbering, and the latest standards will be renamed WiFi 6.
It’s nearly the best thing since sliced bread.
