So earlier this month, we noted how AT&T had pissed off competitors and consumers alike by pretending its existing fourth generation wireless network (4G) was actually 5G. More specifically, AT&T has been changing the "4G" icon on its customers phones to say "5G E," despite the fact that actual 5G service at scale is still probably several years away. Technically, AT&T simply took some of the improvements it recently added to its 4G networks (like better MIMO antennas and more efficient 256 QAM technologies), and decided to call this "5G Evolution" in a bid to pretend it was the first to launch actual 5G.

Competitors and consumers noticed.
