Device-Free Counting via OFDM Signals of Opportunity [PDF]
2018 IEEE International Conference on Communications Workshops (ICC Workshops), 2018 Counting targets (people or things) within a monitored area is an important task in emerging wireless applications for smart environments, safety, and security. Counting via passive radars rely on signals of opportunity (i.e., signal already on air for other purposes) to detect and count device-free targets, which is preferable, in terms of privacy and

Improving Inertial Pedestrian Dead-Reckoning by Detecting Unmodified Switched-on Lamps in Buildings
Sensors, 2014 This paper explores how inertial Pedestrian Dead-Reckoning (PDR) location systems can be improved with the use of a light sensor to measure the illumination gradients created when a person walks under ceiling-mounted unmodified indoor lights. The process
