The big surge of mass installation should be fully underway by mid-2019. This is not about cell phones, but rather factories, autonomous vehicles, ubiquitous collection of data from sensors, surveillance and Smart City technology.
AT&T named the final five cities that will see the company's mobile 5G before the end of 2018: Houston; Jacksonville, FL; Louisville, KY; New Orleans; and San Antonio. The company also said it plans to launch in seven more cities — Las Vegas; Los Angeles; Nashville, TN; Orlando, FL; San Diego; San Francisco; and San Jose, CA — in early 2019.
The company also made the world's first wireless 5G data transfer over millimeter wave with standards-based production equipment on a mobile form factor device.
