AT&T offers nationwide service using 5G NR and 4G LTE technologies. The company offers 5G service in low-band, mid-band, and mmWave radio frequencies. Much of this service operates in common frequency bands used by other carriers, but AT&T's also uses several unique bands: 14, 29, and 30. The company currently has 4G LTE technology deployed in those bands. Band 29 is unusual because it is only used in conjunction with other bands to boost download speed. In band 14, the company operates FirstNet, which gives priority to public safety users. AT&T also operates 5G in the unique lower part (A block) of band 77, also known as the 3.45 GHz band. AT&T Mobility was known as Cingular until 2007.
