TTN Mapper

This app geotags packets from The Things Network and post them to a server. The goal is to map the actual coverage obtained by the gateways in the network. By inspecting this data "good" gateways can be used as role models for the installation of new gateways. It can also be used to fine tune terrain analysis radio coverage simulations (Radio Mobile, etc). All results available at http://ttnmapper.org.

How it works
This app subscribe to the MQTT api to get notified when packets from a node that you carry with you are delivered. Because we assume that your smartphone is close to the node, the location of the packet is deduced using the GPS of your smartphone. The rssi from the packets are geotagged, mapped and uploaded to the ttnmapper server. On the server the data is aggregated in order to show the coverage of every gateway. The maps can be view at http://ttnmapper.org.

You can use any hardware and software running on your TTN node. As long as you know the address of the node you can use it to map the coverage using this app.

Disclaimer: The app periodically updates the current location using the GPS of your smartphone, in order to accurately geotag your node. Continued use of GPS running in the background can dramatically decrease battery life.
