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

This repository contains a cabled, indoor (office environment) and an outdoor (suburban) DASH7 data set. All data sets are formatted as sigmf-data and sigmf-meta files which can be investigated with IQEngine, GNU Radio or MATLAB. The original samples were recorded as complex float 32-bit samples and have been converted to complex signed int 16-bit samples. Below you can find a more extended description of the data sets. ds_indoor.zip: Wireless indoor data set 10 locations 60 packets per location, 10 packets per file pair (SigMF) Fc: 866.5 MHz Sample rate: 7.68 MHz Data type: ci16_le Length: 8 seconds Channel class: Lo-Rate Sync word: 0x0B67 3 Lo-Rate channel recordings per location channel 0 (Fc: 863.0125 MHz), channel 93 (Fc: 865.3375 MHz), channel 186 (Fc: 867.6625 MHz) Payload: 3 bytes [0xAB 0xCD] preceded with a counter byte (0-9) ds_indoor_cabled.zip: Cabled indoor data set 10 recordings per channel 10 packets per file pair (SigMF) Fc: 866.5 MHz Sample rate: 7.68 MHz Data type: ci16_le Length: 4 seconds Channel class: Lo-Rate Sync word: 0x0B67 3 Lo-Rate channel recordings per location channel 0 (Fc: 863.0125 MHz), channel 93 (Fc: 865.3375 MHz), channel 186 (Fc: 867.6625 MHz) Payload: 3 bytes [0xAB 0xCD] preceded with a counter byte (0-9) ds_outdoor.zip: Wireless outdoor data set 20 locations 60 packets per location, 10 packets per file pair (SigMF) Fc: 866.5 MHz Sample rate: 7.68 MHz Data type: ci16_le Length: 8 seconds Channel class: Lo-Rate Sync word: 0x0B67 3 Lo-Rate channel recordings per location channel 0 (Fc: 863.0125 MHz), channel 93 (Fc: 865.3375 MHz), channel 186 (Fc: 867.6625 MHz) Payload: 3 bytes [0xAB 0xCD] preceded with a counter byte (0-9) flowgraphs.zip: Contains 4 folders data_recording Flowgraphs used to record the I/Q data data_conversion Flowgraphs that convert the data to another data type and optionally decrease the length of a data file DASH7_TX DASH7 transmitter flowgraph DASH7_RX DASH7 receiver flowgraph gw_logs.zip: Contains 3 folders indoor, outdoor, cabled Contains all the DASH7 gateway logs per measured channel. locations.zip: outdoor_locations Contains a JSON file with the GPS coordinates of 21 locations and the RX location.
