Coverage Report Map
Data-driven reports of cellular performance in every state, county, city, and ZIP code in the U.S.
What is the Coverage Report Map?
The Coverage Report Map is a map of the United States that shows detailed report of the cellular coverage and performance in every state, county, city, and ZIP code.
Each coverage report is generated by looking at publicly available FCC coverage data as well as our own crow-sourced cellular speed test data.
Each coverage report shows:
- What percentage of the selected area each cellular network covers
- The weighted median for download speeds, upload speeds, and latency
- A ranking of the best carriers for coverage, speed, reliability, and overall performance
- The distributions for download speeds, upload speeds, and latency
- A graph of cellular performance based on time of day
Here's what Maryland's report looks like:
The Coverage Report Map is designed with network enthusiasts in mind.
It is included as part of the CoverageMap Pro subscription.
Data-Rich Reports
Bars, charts, and line graphs make a rich set of data understandable at a glance.
Percentage Covered
See how much coverage each carrier has in a given area.
You'll see the coverage broken down by ratings: none, poor, good, great, and, exclusive to the Coverage Report Map, excellent.
Weighted Median
Weighted median reports eliminate outlier speed tests to uncover the true typical performance of each network in a given area.
View weighted median results for download speeds, upload speeds, and latency.
This is our current benchmark for viewing the typical performance of a cellular network in a given area.
Best Carriers
At-a-glance information on which carrier has the best coverage, speed, reliability, and overall performance in a given area.
Speed Distribution
Speed Distribution is one of the best ways for comparing performance between carriers at a glance.
It shows you how slow the bottom 10% and 25% of speed tests are, the median performance, and how fast the top 10%, 5%, and 1% of speed tests are.
Time of Day
See how cellular data speeds slow down or speed up depending on the time of day.
Three Glorious Views
Style the map in a way that's most helpful to you.
Overall
The map is color-coded based on what network has the best overall performance in each area.
Coverage
Easily see what network has the most square miles covered in each area with this view.
Speed
Color the map based on what carrier has the fastest speeds in each area.
Reliability
See the most reliable carrier in every area using this color view.
How the Coverage Report Map Compares
To our knowledge, nothing quite like the Coverage Report Map exists in a consumer-facing way. You're experiencing the first map of its kind ever made available to the public.
