Researchers at University college of London have applied principles of radar used in defense and designed detector using home based Wi-Fi routers to spy on people across walls. Using the principles behind the Doppler effect, wherein radio wave reflects off a moving object, Karl Woodbridge and Kevin Chetty, at University College London, have built a prototype unit that uses Wi-Fi signals and recognizes frequency changes to detect moving objects. The size of the prototype unit is more or less the size of a suitcase.
