AT&T's current wireless network uses 5G NR, 4G LTE, and 3G WCDMA (UMTS) / HSPA+ technology. All of these technologies are deployed in bands 2 (1900) and 5 (850). The company's 4G LTE network also uses bands 66, 12, 29, and 30. Band 29 is unusual because it is only used in conjunction with other bands to boost download speed. The company also offers faster mmWave 5G service in the central areas of major cities using band 260. The company also operates the FirstNet LTE network for public safety in band 14. AT&T Mobility was known as Cingular until 2007.
