AT&T set to official launch of 5G services this week end.

Although AT&T 5G systems are operational in 12 cities of america, they are in mode of launching the services. It will not be a full fledged service launch though limited to business and will be free for next 3 months. 

So it seems to be more a commercial pilot of the services for AT. The cities being there are Atlanta, Georgia; Charlotte and Raleigh, North Carolina; Dallas, Houston, San Antonio and Waco, Texas; Indianapolis, Indiana; Jacksonville, Florida; Louisville, Kentucky; New Orleans, Louisiana; and Oklahoma City. 

Gartner Senior Principal Analyst Bill Menezes said that AT&T's initial 5G play looks more like a commercially available trial than a true commercial launch.

"They're probably going to be very selective about where they want to launch it, but we'll still be able to learn a few things," Menezes said: namely, the performance of the hot spots, such as whether AT&T's 5G service can be provided to, say, an apartment complex or high-density office building without needing external antennas like the ones employed by Verizon's 5G Home; and the value proposition of AT&T's 5G offering. Mo Katibeh, CMO for AT&T Business, said in a statement that he expects that initial customers will be "innovative, growing businesses."

Menezes added that there are likely to be details about the service that AT&T just hasn't revealed yet. If AT&T is looking to serve the broadband market, for example, 15 GB is a small data bucket — but if its 5G plans zero-rate services such as video streaming, he said, that's a different story.
