We've already gone over how fifth-generation "5G" wireless, while a notable improvement in network speed and performance, has been obnoxiously over-hyped by hardware vendors and cellular carriers. We've also noted that in reality, broad availability of 5G-capable handsets and networks are still quite a few years away, and when products do arrive, they won't, contrary to some claims, magically fix the myriad of problems deeply woven into the U.S. broadband industry, most of which have to do with lobbyist political power and the monopoly domination of cellular tower backhaul.

AT&T's been among the biggest hype generators for 5G, even though its early offerings on this front, while fast, tend to suffer from high prices and low usage caps (did you expect something else?). In addition to over-hyping 5G's impact, AT&T has been busy both distorting what 5G actually is... and dramatically over-stating actual availability. For example, last year AT&T introduced what it called "5G Evolution" wireless connectivity, which wasn't actually 5G, but a collection of tech (specifically 4x4 MIMO (multiple input, multiple output) antenna and 256 QAM technologies) that simply made existing LTE networks somewhat faster.
