ITM / Longley-Rice model for estimating the range of your meshtastic radio.
Click on the map to select a location, then click run model. The colored tiles are where your signal can be received.
Predicted Signal (dBm)
This tool calculates the ITM / Longley-Rice radio propagation model for Meshtastic LoRa radios (www.meshtastic.org). Its purpose is to estimate the range of a Meshtastic radio, using a realistic physics and terrain model.

An effort has been made to choose model parameters which are realistic for meshtastic devices. However, the model does not account for higher-order effects such as reflections from water, structures, or signal degradation by precipitation or vegetation. The results are approximate and should not be used for safety-critical applications.
No location information is stored by this tool.
The propagation engine is based on work by the author of the geoprop-py repository.
This webpage uses the Leaflet library.
Terrain data is from the NASA Shuttle Radar Topography Mission (SRTM).
The required experimental data were gathered using hardware and software designs from www.meshtastic.org.
