New discoveries show that wifi signals can produce more than just a successful high speed internet signal. They are now able to produce signals showing room occupancies.
Scientists say this new discovery, of being able to tell if a room is occupied by a person during a given time, is possible due to radio waves transmitted through the wifi signal.
Researchers at the University of Utah made this discovery recently, and hope to continue with their progress. So far, the team is only able to detect and see through a maximum of three-feet of wall depth. And as far as “people watching” goes, they are only able to detect through-the-wall neighbors when sensory motion occurs. These motions then activate the radio waves, which activate the signals.
But unfortunately, nothing as detailed as say an actual picture of the neighbor can be generated… not yet.
