While it’s true that it’s going to take some time before most of us will actually be able to enjoy the benefits of 5G, that doesn’t mean you can’t sit back and enjoy the fireworks right now. AT&T’s adoption of the “5G Evolution” label has already been controversial among industry followers and fellow carriers alike for watering down the meaning of next-gen connectivity — and now Sprint is looking to do something about it.

The carrier filed suit against what it called “false advertising and deceptive acts” relating to AT&T’s 5G E. The suit notes, rightly, that Sprint, AT&T and other major carriers are all jostling to be first to market, “but calling its network 5G E […] does not make it a 5G network.” In fact, the network is more akin to advanced LTE.

AT&T called itself “[the] first U.S. mobile company to introduce mobile 5G service in a dozen markets by late 2018” courtesy of the label, in a much-maligned attempt to plant its flag. It’s similar to tactics used by the carrier ahead of the rollout of LTE. AT&T has largely waved away criticism, stating that it’s happy that such moves have gotten it into the heads of the competition.

That may be true, but anyone who has watched the industry with even passing interest knows that real network advances take time, and this sort of branding goes a ways toward muddying up consumer understanding. The suit goes on to claim that the 5GE label violates state and federal false advertising laws and does damage to competitors like Sprint, which is invested in the slower rollout of true 5G.

Update: AT&T is standing defiant on this one. Here’s their statement:
