Technology has been created that allows you to “see” through a wall using WiFi

Technology seems to be more advanced than we think. Everything indicates that scientists have been trying to create this technology for a while and now, finally, they have succeeded. But does this technology really work or is it just speculation? Read below and learn all about how the scientists developed the dossier Technology that allows you to “see” through a wall Only using Wifi.

The new technology is developed by scientists

It all happened in the US state of Pennsylvania, where researchers from Carnegie Mellon University got together and together developed a method that detects the 3D shape and motions of human bodies in a diverse environment, just using WiFi routers to get that “view through walls”.

They explained that in order to develop the technology, DensePose was used, which is a system that has the function of mapping pixels on the surface of the human body into an image.

According to Vice, this system was thought of and designed by researchers in London and artificial intelligence (AI) researchers at Facebook.

At that time, according to the recently published article uploaded to the arXiv preprint server, a neural network was developed that determines the phase and amplitude of WiFi, which is sent and received by routers to the coordinates on human bodies.

This research has been going on for some time. Scientists have worked hard to come to this conclusion. They have always tried to “see” people without having to use cameras and radar.

Other researchers have tried to advance the technology

In 2013, at the Massachusetts Institute of Technology (MIT), a team of researchers found a way to use smartphone signals to see through walls. Five years later, another MIT team used WiFi to try to detect people in another room and translate their movements into walking stick shapes.

With the advancement of technology, it has become possible to explore and make many discoveries. The researchers, from Carnegie Mellon University, believe that these signals, i.e. WiFi signals, can act as a ubiquitous sensor.

This will only be true for regular RGB cameras and you can only sense people or their movements in the room. Finally, they said that using WiFi tends to overcome hurdles such as poor lighting and occlusion that regular camera lenses encounter.

It seems that technology is advancing very quickly, every day researchers or scientists make new discoveries. What is left for us is to stay up to date with the news and try to understand how it all works.
