AT&T 5G Evolution launches today with the help of Samsung's Galaxy S8
According to AT&T, 5G Evolution "offers twice the speeds of [its] 4G LTE network." Mind you, this is not true 5G. Actual 5G standards have yet to be finalized, so we won't be seeing any real 5G networks before 2019 the earliest. Nevertheless, 5G Evolution is now here to "pave the way to the next generation of faster speeds," as AT&T puts it.
AT&T says it'll soon launch 5G Evolution in other areas across the US, starting with Indianapolis (sometime this summer). By the end of the year, 5G Evolution should be available in over 20 major metropolitan areas stateside, including Atlanta, Boston, Chicago, Los Angeles, Nashville, and San Francisco.
