Wi-Vi technology helps a person to “see through walls” using the Wi-Fi signals

Researchers at the University College London (UCL) have designed a novel technology which can track the Doppler shifts of the ubiquitous Wi-Fi and smartphone signals, thus helping authorities to “see” people who are moving even behind walls that are 25 centimeters in thickness.

Researchers believe that this novel technology can be used to detect the indoor moving targets for security purposes such as hostage situations. Apart from using it in public defenses the technology also finds it application in various scenarios such as crowd and traffic monitoring and human-machine interfacing.

At the National Instruments’ NI Week 2015 conference held in Austin, Texas from 3-9 August, this innovative technology has won the Engineering Impact Award under the category of RF and Communications .... http://www.techworm.net
