SDR-based IoT Communication Systems: An Application for the DASH7 Alliance Protocol

<p>This repository contains a cabled, indoor (office environment) and an outdoor (suburban) <a href="https://www.dash7-alliance.org/" target="_blank" rel="noopener">DASH7</a> data set. All data sets are formatted as sigmf-data and sigmf-meta files which can be investigated with <a href="https://iqengine.org/" target="_blank" rel="noopener">IQEngine</a>, <a href="https://www.gnuradio.org/" target="_blank" rel="noopener">GNU Radio</a> or <a href="https://www.mathworks.com/products/matlab.html" target="_blank" rel="noopener">MATLAB</a>. The original samples were recorded as complex float 32-bit samples and have been converted to complex signed int 16-bit samples.&nbsp; Below you can find a more extended description of the data sets.</p> <p><strong>ds_indoor.zip:</strong></p> <ul> <li>Wireless indoor data set&nbsp;</li> <li>10 locations</li> <li>60 packets per location, 10 packets per file pair (SigMF)</li> <li>Fc: 866.5 MHz</li> <li>Sample rate: 7.68 MHz</li> <li>Data type: ci16_le</li> <li>Length: 8 seconds</li> <li>Channel class: Lo-Rate</li> <li>Sync word: 0x0B67</li> <li>3 Lo-Rate channel recordings per location <ul> <li>channel 0 (Fc: 863.0125 MHz),&nbsp; &nbsp;</li> <li>channel 93 (Fc: 865.3375 MHz),&nbsp;</li> <li>channel 186 (Fc: 867.6625 MHz)</li> </ul> </li> <li>Payload: 3 bytes [0xAB 0xCD] preceded with a counter byte (0-9)</li> </ul> <p>&nbsp;</p> <p><strong>ds_indoor_cabled.zip:</strong></p> <ul> <li>Cabled indoor data set</li> <li>10 recordings per channel</li> <li>10 packets per file pair (SigMF)</li> <li>Fc: 866.5 MHz</li> <li>Sample rate: 7.68 MHz</li> <li>Data type: ci16_le</li> <li>Length: 4 seconds</li> <li>Channel class: Lo-Rate</li> <li>Sync word: 0x0B67</li> <li>3 Lo-Rate channel recordings per location <ul> <li>channel 0 (Fc: 863.0125 MHz),&nbsp; &nbsp;</li> <li>channel 93 (Fc: 865.3375 MHz),&nbsp;</li> <li>channel 186 (Fc: 867.6625 MHz)</li> </ul> </li> <li>Payload: 3 bytes [0xAB 0xCD] preceded with a counter byte (0-9)</li> </ul> <p>&nbsp;</p> <p><strong>ds_outdoor.zip:</strong></p> <ul> <li>Wireless outdoor data set</li> <li>20 locations</li> <li>60 packets per location, 10 packets per file pair (SigMF)</li> <li>Fc: 866.5 MHz</li> <li>Sample rate: 7.68 MHz</li> <li>Data type: ci16_le</li> <li>Length: 8 seconds</li> <li>Channel class: Lo-Rate</li> <li>Sync word: 0x0B67</li> <li>3 Lo-Rate channel recordings per location <ul> <li>channel 0 (Fc: 863.0125 MHz),&nbsp; &nbsp;</li> <li>channel 93 (Fc: 865.3375 MHz),&nbsp;</li> <li>channel 186 (Fc: 867.6625 MHz)</li> </ul> </li> <li>Payload: 3 bytes [0xAB 0xCD] preceded with a counter byte (0-9)</li> </ul> <p>&nbsp;</p> <p><strong>flowgraphs.zip:</strong></p> <ul> <li>Contains 4 folders <ul> <li><strong>data_recording</strong> <ul> <li>Flowgraphs used to record the I/Q data</li> </ul> </li> <li><strong>data_conversion</strong> <ul> <li>Flowgraphs that convert the data to another data type and optionally decrease the length of a data file</li> </ul> </li> <li><strong>DASH7_TX</strong><br> <ul> <li>DASH7 transmitter flowgraph</li> </ul> </li> <li><strong>DASH7_RX</strong> <ul> <li>DASH7 receiver flowgraph</li> </ul> </li> </ul> </li> </ul> <p>&nbsp;</p> <p><strong>gw_logs.zip:</strong></p> <ul> <li>Contains 3 folders <ul> <li><strong>indoor, outdoor, cabled</strong> <ul> <li>Contains all the DASH7 gateway logs per measured channel.</li> </ul> </li> </ul> </li> </ul> <p>&nbsp;</p> <p><strong>locations.zip:</strong></p> <ul> <li><strong>outdoor_locations</strong> <ul> <li>Contains a JSON file with the GPS coordinates of 21 locations and the RX location.</li> <li>Cointains a map with all the outdoor locations</li> </ul> </li> <li><strong>indoor_locations</strong> <ul> <li>Contains a JSON file with the X and Y coordinates of 21 locations and the RX setup location with respect to a reference point.</li> <li>Cointains a map with all the indoor locations</li> </ul> </li> </ul>
