AT&T has announced plans to roll out a true 5G network in a dozen markets in accordance with the 3GPP’s recently released 5G NR (new radio) guidelines by the end of 2018.

It’s nice to see that AT&T is actually working on a real 5G network, given the company’s announcement of its so-called “5G Evolution” network last year, which largely consisted of the AT&T rebranding existing LTE technologies that competitors had already adopted.

AT&T hasn’t offered too many details, beyond the fact that its network will be based on the newly accepted industry standard for 5. So things like the speeds AT&T will be offering, when this year to expect the roll out, what devices will work with it, or even what the 12 markets will be are all still unclear.

In addition to its true 5G network, AT&T has also said that it will continue to work on expanding its LTE and 5G Evolution networks (a name that it seems the company will be apparently continue to use, which probably won’t be confusing at all to consumers) over the course of 2018.

AT&T is also the last of the four main US carriers to announce its vague 5G rollout plans. Verizon is also planning to have 5G service in five cities by the end of 2018, while Sprint says it will have its network up and running by the end of 2019T-Mobile also announced plans to start rolling out its 5G network in 2019, with nationwide coverage by the end of 2020.
