2. Towards Battery-free Radio Tomographic Imaging : Battery-free Boundary Crossing Detection
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Radio tomographic imaging (RTI) is a novel device-free localization technique which utilizes the changes in radio signals caused by obstruction to enable various sensing applications. However, the deployment of these applications is hindered by the energy-expensive radio sensing techniques employed in these systems. READ MORE
