AT&T on Friday added some detail to its commercial 5G launch plans by identifying three more cities where it will deploy a standards-based mobile service by the end of the year. Charlotte and Raleigh, N.C. and Oklahoma City, Okla., join Atlanta, Ga., and Dallas and Waco, Texas, as among the 12 markets the carrier will turn up its next-generation cellular service.
Based on the details released so far, AT&T will use a hot spot device to provide high-capacity cellular using millimeter wave spectrum.
