AT & T continues to promote the development of its low-band 5G network. Recently, it has added support for 6 cities: New York City, Washington DC, Baltimore, Las Vegas, Detroit, and Philadelphia. . Like the 5G network launched earlier in December last year, the six new cities also use the company’s conventional 5G network based on its low-band 850MHz spectrum technology.
In addition to the introduction of low-frequency bands, AT & T will also launch mmWave 5G + networks in parts of Baltimore and Detroit, but 5G + networks are not yet open to ordinary users.
These six new cities bring AT & T’s total 5G supported cities to 19 (5G + cities totaled 25), but the operator has so far launched only one 5G phone: the $ 1300 5G version of the Galaxy Note 10. Nonetheless, the addition of metropolitan areas such as New York and Washington is encouraging AT & T, especially as more 5G devices will arrive in 2020.
