TROPPO LoRa:
TROPospheric Personal Observatory using LoRa signals

With the growth of LoRa deployments there are plenty of anecdotal reports of very long wireless links, well beyond the line of sight. Most reports suggest that these links are related to anomalous tropospheric propagation. TROPPO allow to study tropospheric links based on TheThingsNetwork, a popular LoRaWAN-based infrastructure.

TropoProbes

We have only deployed three TropoProbes and have already detected tropospheric propagation. We would like to engage the TTN community to add more devices to the platform. Get in touch!
