Since electromagnetic signals are omnipresent. Radio Frequency (RF)-seiisting has the potential to become a universal sensing mechanism with applications in localization, smart-home. retail, gesture recognition, intrusion detection, etc. Two emerging technologies in RF-seusing, namely sensing through Large Intelligent Surfaces (LISs) and mm Wave Frequency-Modulated Continuous-Wave (FMCW) radars, have been successfully applied to a wide range of applications. In this work, we compare LIS and mmWave radars for localization in real-world and simulated environments. In our experiments, the mm Wave radar achieves 0.71 Intersection Over Union (IOU) and 3cm error for bounding hoxes. while MS has 0,56 IOU and tflcni distance error. Although the radar outperforms the LIS hi terms of accuracy. LIS features additional applications in communication in addition to sensing scenarios.
