AT&T Wireless Coverage

4G LTE Coverage

AT&T's 4G LTE network covers most of the U.S. but trails behind T-Mobile and Verizon in certain areas. While AT&T's network spans every state, some states—such as Alaska, Arizona, Maine, Nebraska, Nevada, and Wyoming—have only 60% or less coverage.

• 4G LTE Benefits: Enables fast data speeds, calls, and texts.

• Comparison: AT&T ranks third in 4G LTE coverage, trailing T-Mobile by 1% and Verizon by 12%.

3G Coverage

AT&T leads in 3G coverage among major U.S. carriers. Though slower than 4G LTE, 3G networks provide broader coverage, especially in rural areas.

• Pros: Wider reach and reliability in remote locations.

• Cons: Slower data speeds compared to 4G LTE.

AT&T 5G Rollout

AT&T planned to introduce 5G services for fixed applications (homes and businesses) by late 2019, with mobile 5G availability in 19 cities, including:

• Major cities: Dallas, Houston, San Francisco, Los Angeles, Orlando, Las Vegas, and more.

• Technology: Uses mmWave spectrum at 28 GHz and 39 GHz, with a broader 5G rollout expected using the 39 GHz spectrum.

AT&T has also rebranded its advanced 4G network as “5G Evolution”, a stepping stone toward true 5G connectivity.

How AT&T Coverage Maps Are Calculated

Coverage maps rely on:

1. Cell Tower Locations: Placement and density of towers.

2. Tower Power and Range: Strength of signal transmission.

3. Environmental Factors: Mountains, buildings, and foliage can obstruct signals.

Even areas marked as covered may experience connectivity issues due to obstructions, requiring solutions like signal boosters or femtocells.
