Telecompetitor has the details:
AT&T nationwide 5G plans include a multi-pronged strategy. Those plans include leveraging millimeter wave spectrum for dense urban areas. AT&T calls this their 5G+ coverage, which will provide the fastest mobile broadband experience.
This service will be delivered primarily through small cells using a centralized radio access network (CRAN) architecture. CRAN allows multiple (maybe hundreds of) small cells to be controlled from a single centralized hub. AT&T 5G+ is currently available in select locations in 19 cities. It can offer gigabit capable speeds, notes Mair.
“I really like the momentum I’m seeing right now from our build in terms of the CRAN or small cell capabilities,” said Mair in his remarks. “That millimeter wave, basically 200, 300 plus meters radius, so there’s a lot more of those small cells that you need to put in place to provide that capability.”
For broader, more macro coverage, AT&T will use their sub-6 GHz spectrum holdings, with 700 MHz a likely 5G workhorse. This capability will be put on existing AT&T towers, with their FirstNet build helping facilitate the transition to 5G.
