Engineers of the University of Utah developed a new wi-fi network – no the one used by the computers – that is capable to create waves that are capable of “see” movements through walls.

The technology that was developed by Joel Wilson and Neal Patwari in the university’s Department of Electrical and Computer. It uses radiate tomographic imaging (RTI), which can “see,” locate and track moving people or objects in a surrounded area by inexpensive radiate transceivers that send and receive signals.

Although the reach of the waves is not very wide, an advantage of the system developed by the researchers is that are not necessary expensive equipments create a network of this kind.

Radiate tomographic imaging (RTI) is different and much less expensive than a radar system, and it works in a very similar way to medical CT (computerized tomographic) scanning, which use X-rays to make pictures of the human body. Besides, differently of the optical and infrared imaging systems, it is capable to cross solid objects and it doesn’t represent any danger to the health.

And which would the applicabilities of that system be in our daily life?

The researchers affirm that this system can be very useful to help in other critical situations of safety (when there is the need to rescue hostages), and also to help firemen (to rescue faster people inside of buildings in fires). Besides, the technology can be modified and be improved to detect even the movement of the fires inside of a building, something that will be very welcomed by the FD around the world.

Finally, it is a technology that certainly will be well accepted in our society because it can make the difference between the life and the death.
