The locations are part of a 12-city roll out the carrier has committed to for 2018. Dallas, Atlanta, and Waco were previously announced as roll-out areas for the 5G service.

So far, at least, AT&T is avoiding dense population zones like New York, LA, and San Francisco. The company says this is a deliberate move and it intends to launch the 5G service in a blend of big and mid-sized cities “to avoid a new digital divide.”

5G mobile service is roughly 10 times faster than 4G and many companies say it will be a breakthrough technology that eases wireless data transfers.

Mayors of the cities added to AT&T’s 5G list were understandably enthusiastic about the decision.

“In a global, interconnected economy, access to the most advanced technology is vital for creating jobs and driving economic growth that benefits everyone in a community,” said Charlotte Mayor Vi Lyles. “Access to 5G technology can make a genuine difference in the lives of families.”

While there’s certainly reason for excitement, there is one part of the puzzle the cities and carrier aren’t talking about.

To take advantage of AT&T’s 5G, you need a phone that works with the service. And there aren’t any on the market yet. (They’re expected to become widely available in 2020.)

AT&T is not the only mobile company working on 5G service, of course. Verizon plans a limited launch later this year. And T-Mobile and Sprint are readying for a 2019 launch.
