> it's perfectly appropriate to apply Wi-Fi to any wireless TCP/IP networking device

Until you try to explain to your Uncle Ed why his laptop can't access the eBay even though they just rolled out the Super-WiFi in his region.



Uncle Ed's laptop may not get 802.11 n or 802.11 ac (maybe not even g) either even those are all official "Wi-Fi" protocols.


An n-only device probably wouldn't get certified as Wi-Fi™; AFAIK Wi-Fi devices have to have b and g for precisely that compatibility reason.
