Because of this, this map is the first ever standardized look at 4G LTE mobile data and voice service availability. These standard parameters are intended to create a more uniform and consistent comparison of coverage among service providers than has previously been available through the FCC’s Form 477 process.

The coverage map was created using data submitted voluntarily by the four mobile carriers using certain standardized propagation model assumptions or parameters that were established by the FCC as part of the Broadband Data Collection. Users can choose to view providers’ mobile data and/or voice service by clicking on a provider’s data or voice service layer. How to Use the MapĬonsumers can enter in specific addresses or zoom in to locations to see where 4G LTE mobile data and voice service is available. 4G LTE data service meeting a 5/1 Mbps minimum speed may not be available in areas where only voice coverage is shown on the map. Voice coverage areas represent where customers should expect to make and receive mobile voice calls and send and receive texts over the 4G LTE network, without regard to throughput speed. The map includes separate layers for each carrier’s broadband and voice coverage.


Specifically, it shows where customers can expect to receive 4G LTE broadband service at a minimum user download speed of five megabits per second (5 Mbps) and a user upload speed of one megabit per second (1 Mbps) based on propagation modeling. This map shows the 4G LTE mobile coverage areas of the nation’s four largest mobile wireless carriers: AT&T Mobility, T-Mobile, UScellular, and Verizon.
