This New Tech Will Let You See Through Walls Using Wi-Fi

German scientists have found a working method to take 3D holograms of objects inside a room, from the different room. The technique had been developed by Philip Holl and Friedemann Reinhard of the Technical University of Munich. To recall, back in August 2016, 3D-imaging sensor company based in Israel has developed a 3D-imaging sensor for Android smartphone that allows phones to peer right through the walls. Well, something similar had been discovered now. We all are known to the fact that Wi-Fi can pass through walls and it helps us to surf the internet by sitting anywhere within the reach of Wifi. However, what if you can use this wifi technology to scan through the walls to get an idea of what’s there? Well, German scientists have found a working method to take 3D holograms of objects inside a room, from the different room.

This New Tech Will Let You See Through Walls Using Wi-Fi

Well, the technique had been developed by Philip Holl and Friedemann Reinhard of the Technical University of Munich. All of the radiation getting out of the router doesn’t address it to our smartphones, or computers. Rather, they bounce off different objects.

Well, the researchers have utilized this characteristic of Wifi to develop 3D pictures of objects inside a room. Philip Holl said “The past two years have seen an explosion of methods for passive Wi-Fi imaging”

The method uses Wifi signals to scan a room. Using two antennas, they register a Wi-Fi field circling a particular room. Well, these two antennas are used to obtain the phase and intensity of the field, both from source spot and areas it bounces off.

This method gives the holographic picture of the room which can be used in various kind of applications. Well, this method will be very useful in case of rescue operations like after avalanche or earthquake.

Well, such inventions also open new privacy exploitation issue. Friedemann Reinhard said in a press release “It is rather unlikely that this process will be used for the view into foreign bedrooms in the near future. For that, you would need to go around the building with a large antenna, which would hardly go unnoticed.”
