Iowans, we’re going to have to wait. We’re not among the three cities AT&T says will get zippier mobile service — aka 5G. AT&T announced late Tuesday that it will first roll out 5G to three locations: Dallas and Waco in Texas, and Atlanta, according to CNN Tech. The article says the company will announce more cities in the coming months. 5G, heralded as the next generation of wireless network technology, is about 10 times faster than 4G, according to experts. That’s enough to download a 3-D movie in 30 seconds. It would take six minutes on 4G.
