Measuring Through-the-Snow Radiowave Propagation of LoRa Signals with Two Different Snow Profiles

Thanks to technological advancements in Search and Rescue (SaR) technology, trough-the-snow propagation of the LoRa protocol can foster operations. Herein, we report the raw data collected during a measurement campaign including a transmitting LoRa radio buried under the snow while the snow is completely profiled by nivologists. Preliminary data suggest that the wetter the snow, the more localized the signal attenuation around the transmitter is, even though the path loss is less affected by the snow type after about 20 meters
