Performance analysis of wireless devices for a campus-wide IoT network

To select an appropriate technology for the deployment of an Internet-of-Things (IoT) network inside the Indian Institute of Science (IISc) campus, we first compare available wireless technologies based on their data sheets. After selecting two of the best available sub-GHz devices, we characterize them by performing controlled lab experiments. Next we test these sub-GHz modules in different real world environments such as open ground, straight road, moderately and densely wooded area, inside a concrete building and on building roof-tops. We then compare their performances for characterization of the wireless channels in different environments. In the end, we propose a sensor and network plan towards monitoring water resources inside the IISc campus.
