This repository contains all elements of a large-scale LoRa measurement study, performed by the "Multimedia Communication Lab" (MCLab) at the Hochschule Bonn-Rhein-Sieg, University of Applied Sciences in 2020/2021 in cooperation with Fraunhofer FKIE. It includes the schematics and the source code of our own developed LoRa based GPS sensor which were mounted on garbage trucks to measure the signal strength of several LoRa gateways located in the city of Bonn, Germany. A first evaluation and analysis of the data is provided as well as the raw measurement records. In doing so, we hope to stimulate further research on this topic.
We encourage researchers working with this data and repository to cite this VTC2021-Fall paper or directly use the following BibTeX entry. The author version of the paper can be found here on arxiv.
