It’s also hella confusing because there’s not a marketing or real protocol name attached beyond the “5G” moniker, at least not that I could easily find.

I can name GPRS, EDGE, UMTS, HSPA, 1xRTT, EVDO, WiMAX, and LTE off the top of my head and tell you what “G” they are associated with (1, 2, 3, 3.5, 2, 3, 4, 4 respectively).

5G is a vaporous term with no real definition right now other than “whatever the fuck the ITU has decided to call 5G”.

EDIT: I guess they’re calling the air interface “5G NR (New Radio)”. How memorable. Guess with everyone finally getting on the same page with LTE in the current generation they felt no need to come up with a real name.
