Measurement of LoRa signal propagation in urban areas utilizing aerial gateway and ground gateway

In this study, a comprehensive measurement of a large-scale LoRaWAN network in an urban environment was conducted. Specifically, 28 LoRaWAN end-devices have been deployed in various locations, covering outdoor, indoor, and multiple floors of buildings. Moreover, an aerial gateway mounted on the DJI Mavic 3, along with three ground gateways, has been deployed for data collection. The performance of aerial gateway at altitudes of 50m, 100m, and 150m was also tested. Finally, a total of 28,576 raw data entries were obtained, including valuable information like RSSI, SNR, and timestamps.
