After AT&T decided to start rolling out "5G Evolution" branding on phones and networks that use 4G LTE Advanced technology, competitors have had to make decisions on how to respond. While T-Mobile mocked it with a sticker, Verizon (Engadget's parent company) fired off a letter. So what is Sprint going to do? It has filed a lawsuit in federal court, seeking an injunction to prevent AT&T from using 5GE tags on its devices or advertising.
In its claim, Sprint said it commissioned a survey that found 54 percent of consumers believed the "5GE" networks were the same as or better than 5G, and that 43 percent think if they buy an AT&T phone today it will be 5G capable, even though neither of those things are true. Sprint's argument is that what AT&T is doing is damaging the reputation of 5G, while it works to build out what it calls a " legitimate early entry into the 5G network space."
