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.
