AT&T has been placing a big focus on its low-band 5G network, regularly expanding it to new markets throughout the year and recently announcing that it had reached "nationwide" status. Today, though, AT&T is switching things up and expanding its high-band 5G coverage.
AT&T today launched its 5G+ service in downtown Milwaukee, WI. If you find yourself in downtown Milwaukee with an AT&T 5G+-capable device, you'll be able to get 5G+ coverage at the Fiserv Forum, in Miller Park, and in the Deer District.
In total, the 5G+ service is available in parts of 36 cities.
AT&T customers in those 36 cities will need a 5G+-capable device to access that coverage. Those include the Samsung Galaxy Note 20 Ultra, Galaxy Z Fold 2, Galaxy S20 Ultra, Galaxy S20+, and Galaxy Z Flip, as well as the upcoming Google Pixel 5.
5G+ uses millimeter wave (mmWave) spectrum, while AT&T's regular 5G uses low-band spectrum. With mmWave, you can get super-fast speeds — AT&T touts that its 5G+ offers download speeds up to 1Gbps — but mmWave signals can't reach very far and aren't great at penetrating buildings. Meanwhile, low-band 5G can reach long distances, but it isn't nearly as fast as mmWave.
