AT&T Communications has confirmed that its original 5G network – which was launched in December 2018 using 39GHz millimetre wave (mmWave) frequencies – is now available in parts of 35 US cities. This service, referred to as ‘5G+’ by the telco, offers ‘extra speed and capacity to serve high-traffic areas such as arenas and campuses’ and now covers locations such as Baltimore, Cleveland, Detroit, Miami, Oakland, Philadelphia and Phoenix.
Meanwhile, AT&T’s low band 5G service, which went live in ten markets on 13 December 2019, is now operational in 19 markets, following launches in the likes of Baltimore, Buffalo, Detroit, Las Vegas, Louisville, New York City, Philadelphia and Washington, DC. This network utilises former 3G spectrum in the 850MHz band and is expected to be made available on a nationwide basis in the first half of 2020.
