Device-Free RF Residential Monitoring System
Radio tomographic imaging (RTI) can localize people by monitoring the changes in the radio frequency (RF) attenuation field of an area where a wireless network is deployed. The technology does not require people to carry any electronic device. This video shows an RTI system developed by a team of researchers from Finland's Aalto University and the University of Utah. The residential monitoring system is deployed in a typical single floor, one-bedroom apartment with the aim to localize the resident during daily activities. The video spans a ten minute period.
