One week after naming Indianapolis as one of the first cities that'll get its mobile 5G coverage, AT&T has revealed another five soon-to-be 5G towns.

AT&T says that it plans to deploy mobile 5G in parts of Houston, Jacksonville, Louisville, New Orleans, and San Antonio in 2018. These five cities join the other seven cities that'll get AT&T 5G this year: Atlanta, Charlotte, Dallas, Indianapolis, Oklahoma City, Raleigh, and Waco.

In early 2019, AT&T's mobile 5G coverage will continue to grow. AT&T plans to roll out mobile 5G in parts of Las Vegas, Los Angeles, Nashville, Orlando, San Diego, San Francisco, and San Jose early next year.

AT&T today also touched on a recent 5G milestone that it completed. The big blue carrier says that it made the world's first standards-based mobile 5G millimeter wave (mmWave) connection. It made a call between a 5G base station in the field and a "smartphone form factor 5G device" that included a Qualcomm Snapdragon X50 5G modem and RF subsystem.
