3G/4G Performance Map: Data Speeds for AT&T, Sprint, T-Mobile, and Verizon
How to Use the Map: We tested wireless service in 13 cities, and in each city we tested in ten locations. The map below displays our test results for each location.
To zoom in on a city, use the navigation controls at the upper left of the map, or click repeatedly on or near the group of map pins.
Click the blue pins to display the results. You'll find download and upload speeds (in megabits per second), network latency (in milliseconds), and Web page download and video stream times (in seconds) for both the 3G and 4G services of the four national wireless carriers.
