Device Free Localization (DFL) technology leverages real-time collection and processing of heterogeneous radio signal streams (e.g., those found in 4G/5G and WiFi connections) and multiple Channel State Information (CSI) between different links/antennas. Perturbations induced by moving bodies/objects on the EM wavefield can be processed to extrapolate a 2D image of humans and the environment. DFL is designed to perform real-time tracking of non-instrumented subject/object motions (humans, robots, machines) in line-of-sight, non-line-of-sight, and through-the-wall scenarios. The prototype is based on a network of  IEEE 802.15.4 compliant wireless devices (from 8 up to 50) and can be deployed according to arbitrary layouts. It is designed to track one human subject in a human-robot shared space. Below some video demos.
