LoRa RSSI vs distance

<p>The data set has been used in CityScan experiment within <a href="https://www.fed4fire.eu/">Fed4Fire+</a> 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.</p> <p>The data set contains location information transferred over LoRa from a single tag and registered by 10 nodes from <a href="https://doc.lab.cityofthings.eu/wiki/Nodes">CityLab testbed</a>:<a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node2"> Node 2</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node4">Node 4</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node15">Node 15</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node18">Node 18</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node20">Node 20</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node21">Node 21</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node27">Node 27</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node33">Node 33</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node35">Node 35</a>, <a href="https://doc.lab.cityofthings.eu/nodemap/?focus=node36">Node 36</a>.</p> <p>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</p>
