AT&T 4G LTE Footprint
With the Nov. 20 launches, AT&T 4G LTE will be available in 15 markets: Athens, Ga., Atlanta, Baltimore, Boston, Charlotte, Chicago, Dallas-Fort Worth, Houston, Indianapolis, Kansas City, Las Vegas, Oklahoma City, San Antonio, San Juan, Puerto Rico, and Washington, D.C.
AT&T is the only U.S. carrier providing 4G using both HSPA+ and LTE technologies. HSPA+, when combined with enhanced backhaul, provides customers with compatible devices 4G speeds, meaning customers get a faster and more consistent 4G experience, even when outside of an AT&T 4G LTE area. Customers of other carriers that have transitioned to 4G LTE without further speed upgrades to their existing networks are likely to see a jarring drop-off in speeds when they move out of LTE coverage.
