Network as a Sensor in Agriculture

Communication systems such as public land mobile networks (e.g., 4G/LTE networks) or low-power IoT networks are ubiquitous, nowadays. Temporal variations of the signal strength of such systems can be leveraged for low-cost crop and soil sensing.
The goal of this thesis is to develop new approaches for approximating crop and/or soil parameters.
These approaches will be implemented, deployed, and evaluated on agricultural fields.
