see through wall

U.S. scientists are experimenting with the technology of Wi-Vi , which, according to them, allowing you to see and track moving objects through walls , using an inexpensive, widely available wireless system. The technology can be implemented in a smartphone or a special portable device for use in search and rescue or military operations, the author assures the development Katabami Dean, professor at the Massachusetts Institute of Technology.

Mrs. catabolism and her assistant, a graduate student Fadel Adib, believe that they have developed technology that can be used not only law enforcement, but also by ordinary users. The system, for example, may prevent the illegal invasion of private land. All the anxiety that your neighbors will be able to spy on you when you are changing, in vain. In its current form the display device is more like a radar tracking of aircraft, rather than X-ray machine. However, scientists continue to work to increase the resolution of the image, so do not be surprised if one day the system will be able to recognize faces. problem of information security is very relevant today. The public is concerned about the safety of the use of Google Glass .

What is the Wi-Vi, the video shown below.

“It all depends on how we are going to use technology,” – says catabolism.

Wi-Vi sends signals via Wi-Fi wall and receives reflections of these signals. The device works on the principle of radar or sonar. But unlike the latter, Wi-Vi dispenses with cumbersome and expensive equipment.

The main advantages of Wi-Vi researchers call a low cost, low power and compact size. Heart technology is a coding scheme which may be made of silicon. The apparatus may be incorporated into the cellular phone, and the cost does not differ from conventional module Wi-Fi.

“All the components used by us are available in portable Wi-FiĀ», – says catabolism.

Given all the advantages of the technology, Wi-Vi can be widely distributed. Modern radar systems in service with the U.S. military transported by truck. U.S. Army needed a more portable equipment, said catabolism.


Opportunities Wi-Vi may be useful to rescuers performing search and rescue work in disaster areas. The police may use Wi-Vi-device for detecting the number of people in the building and tracking movements, for example during the rescue operation. According to the developers, the technology could also find application in games.

Low resolution images on the screen may seem a disadvantage, but in reality it is not. As such, the technology does not threaten privacy and may be used to monitor the elderly or disabled, who do not wish to install video cameras in their room.

But be that as it may, the ability to observe what is on the other side of the wall, raises questions that the law does not give clear answers.

Meanwhile, advocates of personal information requested from Google to reveal all the details about Glass, considering digital Points threat of privacy .
