We are the world leader in IoT network coverage maps.

Use the links in the menu above to view coverage maps or have a look at our blog to learn more! is a service that shows the measured coverage for the IoT networks like Helium IoT and The Things Network. The coverage is measured by users of the network that do drive tests, and provide the data to this mapping service. Data is aggregated into a heat map, but is also available in raw format under advanced maps.

TTN Mapper was the first version of the service that mapped the coverage of The Things Network. The same technology is used in a larger scale to map the coverage of the hundreds of thousands of Helium hotspots.
