Sprint filed a lawsuit with the U.S. District Court on February 7, suggesting that AT&T's so-called 5G service is only an enhanced fourth-generation long-term evolving wireless service, namely 4G LTE-Advanced, which is no different from the services provided by all major wireless operators. In Sprint's view, AT&T uses the terms 5GE and 5G Evolution in order to gain a competitive advantage and belittle other carriers'true 5G. AT&T also claims that research shows that consumers believe 5GE has reached or exceeded 5G. Sprint is seeking to remove 5G-related brands from AT&T's network until it fully meets the 3GPP 5G standard and requires that 5GE-related advertisements be suspended and other carriers be compensated for revenue losses.
Since AT&T launched 5G Evolution, its competitors have criticized and boycotted the brand, and have now entered the legal process. AT&T has defended this on many occasions, and made it clear during last month's CES conference that its competitors are totally jealous of AT&T.
After Sprint filed a lawsuit, AT&T defended the 5G Evolution (5GE) brand. AT&T said in a public statement that 5G Evolution's explanation of technology is very clear, including LTE-Advanced technology, and it is indeed a "standard-based 5G evolution step". "We understand why our competitors don't like what we're doing, but our customers like it." "Customers want to know, and should know, when they will get better speed," AT&T stressed in the statement.
The statement also pointed out that Sprint's assertion in the lawsuit seemed to contradict the official review of its proposal to merge with T-Mobile US. Sprint was forced to compromise with the Federal Communications Commission (FCC) that it would not deploy a broad 5G network without T-Mobile. However, Sprint claimed in the lawsuit that it would soon launch "legitimate 5G technology".
AT&T said it would continue to build 5G Evolution in addition to developing 5G mobile based on international standards. In addition, AT&T also announced that more than 1.5Gb/s of speed was measured in the field test of updating 5G software. This test is based on the prototype of mobile devices and the existing 5G network. AT&T intends to apply this technology to its next generation network as soon as possible.
