You technology advancesespecially with regard to Internet and Wi-Fi, provide a wide range of uses beyond simply distributing connectivity. However, as researchers explore the possibilities of these technologies, some have thought outside the box.
In 2018, a group of researchers aware that we are surrounded by Wi-Fi electromagnetic waves and that these waves can be distorted, began a groundbreaking study.
The essence of this study lay in the idea of using Wi-Fi waves to see through solid objects, revealing what was on the other side.

The exhibit was fascinating: Instead of relying on traditional imaging technologies like x-rays or ultrasound, the research explored the ability of Wi-Fi waves to penetrate objects and return information about what was hidden.
Studies in 2023
In the picturesque town of Santa Barbara in sunny California, a group of minds shiny at the University of Santa Barbara triggered a technological revolution. A fascinating evolution of the discovery made in 2018 is now unlocking a future full of possibilities.
Imagine a scenario where, thanks to this new equipment, we can glimpse what is on the other side of a solid wall. This achievement resembles the operation of underwater sonar, but with a 21st century high-tech twist.
Many may wonder what is different about this new technology. To answer this, the project’s researchers incredibly demonstrated that it was even possible to see a word through the wall.
How does the invention work?
The experiment is remarkably ingenious. Three devices emit electromagnetic waves in the 2.4 or 5 gigahertz range, traversing the wall with millimeter precision.
On the same side of the wall, a small and agile drone takes on the role of observer, capturing and deciphering the signals reflected by objects or people on the other side.
It’s as if Wi-Fi waves became a kind of digital sonar, illuminating what was previously hidden from our eyes.

This technological innovation has the potential to revolutionize various areas, from security, search and rescue to medical and archaeological applications.
Imagine rescuers being able to locate survivors in collapsed buildings after an earthquake, or archaeologists uncovering secrets buried beneath ancient ruins, all thanks to this advancement in Wi-Fi technology.
However, with advances come great responsibilities. Ethical and privacy issues arise as this technology becomes more sophisticated.
It is crucial that research and development of these capabilities continues to be conducted carefully and within strict guidelines to ensure there is no abuse or hacking of privacy.
In Santa Bárbara, a journey of discovery continues, including the future of Wi-Fi technology in store for increasingly exciting surprises.
As we explore the depths of electromagnetic waves, we move towards a world where physical barriers are no longer as impenetrable as they used to be, opening up new possibilities for humanity.
