Technology Wi-Vi will see through walls
A group of researchers from the Massachusetts Institute of Technology have developed a new technology called Wi-Vi, which allows you to track the movement of objects through walls. New uses for inexpensive radio transmitters that can be installed virtually anywhere.
At MIT, says that the new sensors Wi-Vi in the future can be embedded in smart phones, other handheld devices, equipment for police and fire services. Katabami Dean, MIT professor and one of the developers of technology, said that the new technology can be used to create home security systems that would allow the owners of houses to see who is hiding behind the walls of the home.
"Do not worry about what the neighbors will spy on you, considering you are wearing pants or not. System displays images at a very low resolution," - says catabolism. By its action it resembles aircraft radars that monitor the aircraft itself, but not provide information about what is happening in his cabin.
Katabami says that, technically, the accuracy of the system could be improved and then Wi-Vi will be able to recognize faces, but in this case the system Wi-Vi in the sale would be limited. "Like all technology, our depends on how you use it "- says catabolism. New works by sending WiFi-waves through the obstacle detection and how they will be reflected. Similarly, working radar or sonar.
However, there are no powerful antennas and bulky equipment with restricted frequencies. The system relies on two different types of radio signals that bounce and give an idea about the movements on the other side of the wall. Moreover, all the components of the system - a standard for devices that are in most modern smartphones.
From the point of view of energy consumption Wi-Vi corresponds exactly to the WiFi. "The vision through the walls can be useful not only in the consumer, but also in the military sphere as well as mobile transmitters to carry with you," - says catabolism.
