==== Coverage
[https://wiki.cosmos-lab.org/wiki/Architecture/Deployment/Measurements Coverage measurements] were performed in the area around {{{md1}}} in February and March 2022. In total, around 100 measurements have been taken on sidewalks in the area spaced by roughly 5m. The measurement results are presented below.
