LoRa RSSI vs distance

The data set has been used in CityScan experiment within Fed4Fire+ continuous call. RSSI and packet loss between LoRa end device sending data packets and a set of stationary LoRa nodes were studied depending on the distance and other parameters. The data set contains location information transferred over LoRa from a single tag and registered by 10 nodes from CityLab testbed: Node 2, Node 4, Node 15, Node 18, Node 20, Node 21, Node 27, Node 33, Node 35, Node 36. The data is stored in CSV format (with the following columns):<br> <strong>node</strong> - id of the CityLab testbed node<br> (<strong>node_lat</strong>, <strong>node_lon</strong>) - GPS coordinates of the node<br> <strong>tag</strong> - id of the CityScan tag<br> (<strong>tag_lat</strong>, <strong>tag_lon</strong>) - GPS coordinates of the tag<br> <strong>tag_speed</strong> - Speed of the moving tag<br> <strong>dist_m</strong> - Distance between corresponding tag and node (meters)<br> <strong>ts</strong> - timestamp (milliseconds since the UNIX epoch: 1 January 1970)<br> <strong>num</strong> - a sequential number of submitted packet<br> <strong>rssi</strong> - received signal strength indication<br> <strong>received</strong> - Boolean attribute indicating whether or not the data packet was received
