AT&T: Mobile 5G coming this year to Atlanta, Dallas, Waco, nine more

In early January, shortly after AT&T told us that they had plans to launch mobile 5G before the end of 2018, the collective eye-roll throughout the industry could be felt far and wide.

AT&T said its 5G network should be 10 to 100 times faster than 4G. The other major wireless networks also promise a 5G network, but AT&T and is the first to announce an official rollout. More cities will get the same connection in the next few months. AT&T hints that it's working to make sure there's 5G hardware of some sort available in late 2018, but it'll probably be 2019 before there's any kind of selection.

AT&T has recently posted a press release about its plan to offer 5G to consumers in a number of cities in the US.

The 5G that AT&T is rolling out this year will only use millimeter-wave spectrum, which means that it will function very differently to our current LTE cell networks.

"You have to jumpstart the ecosystem", Mansfield said.

Just how fast will 5G go?

"Our mobile 5G deployments this year will be based on 3GPP standards". But Georgia is often a testing ground for new AT&T products and services, with the company recently testing a new technology in a rural part of the state called AirGig to deliver super-fast internet service via power lines.

Telecom operators are expected to invest about $275 billion in infrastructure for 5G, according to research by consulting firm Accenture.

With a mobile 5G network and a compatible 5G smartphone, customers can expect multiple gigabits per second speed on their devices with lower latency. That level of 5G is likely years away, though mobile 5G is a promising place to start.
