CNN Money: Xandem's security sensors can see through walls

(CNNMoney) -- Imagine a real-life version of Harry Potter's magical Marauder's Map, which showed the location of everyone prowling throughout Hogwarts castle. That's what startup Xandem is building: a new kind of all-seeing motion-detection system that's poised to shake up the security market.

There are many different ways to track motion, but most commercial systems rely on optical beams that require uninterrupted sight lines. Heat-sensing infrared systems don't have that weakness, but they're prone to false alarms and can be blocked by anything that insulates body heat.

Xandem uses its super powers to take "Innovation Idol" title

With a fast-moving presentation and demonstration of wireless sensor technology that “looks” through walls, Joey Wilson of Xandem took the title of “Innovation Idol” at a Leonardo After Hours event in Salt Lake City event on December 7, 2011. An audience of 175 cast their votes for one of four innovative research and development projects in a speed pitch contest, and awarded Xandem with the first place prize.

Technology that can see through walls goes commercial [Video]

SALT LAKE CITY -- Joey Wilson's Ph.D. project started a few years ago, a crude experimental network of transmitter-receivers. They tracked people inside by analyzing disturbances of the radio waves. Still, it was an entirely new kind of motion detector - one that could detect burglars through walls, which gave the project immense potential.

Now, the first commercial product is ready to be plugged in. Wilson's company, Xandem, even has its first customer - a penthouse owner in Dubai.

"Yeah, we're ready to generate revenue. Do I think we've solved the problems that we want to solve? Not even close. We're at the tip of the iceberg on what this technology can do," said Wilson. He says his product has big advantages over the infra-red detectors on the market now, which are prone to false alarms because they are sensitive to heat. Read the full story here.

Barron's Article Discusses Xandem Technology

Barron'sXandem was recently mentioned as an example of the University of Utah's ability to commercialize new technologies.

"The technologies driving the new businesses are developed by students working under faculty guidance. Case in point: Joey Wilson, who graduated with a doctorate in electrical engineering last year, is now the CEO of Xandem—a company he started in 2009 while attending U of U. The radio-wave technology he developed allows the company's customers to see through walls.

While Wilson and a professor came up with the ideas and developed the technology, the intellectual-property rights remain with the university, which receives a check for as long as the technology is used. D'Ambrosio says that more than 80 universities have sent representatives to the university this year to study ways of replicating its intellectual-property-rights revenue stream."

Xandem featured in Utah Technology Council newsletter

UTCXandem was recently featured by the Utah Technology Council "Under the lens" newsletter. Here's an excerpt:

"What is most interesting about your company's internal culture?

We question everything. We don't follow typical ways of doing things unless we are absolutely convinced that the conventional methods hold up to our questioning. This comes into play in everything we do, from business decisions to our cutting-edge technology research. We understand that true innovation simplifies old complicated frameworks..."

Discover Magazine - X-Ray Vision Is So 20th Century

Xandem's technology was featured in the May 2010 Print Edition of Discover Magazine in an article entitled X-Ray Vision Is So 20th Century.

Xandem featured media."Researchers are building new systems that see through walls using radiation that's a lot safer than X-rays."

"At the University of Utah, engineer Neal Patwari and doctoral candidate Joey Wilson [Xandem founders] are using radio waves to see through obstacles. Their network of radio transceivers measures the signal strength to reveal the locations of people or objects in the area. The system can find targets in the dark and through walls, smoke, or trees. Patwari and Wilson are currently working to expand the transceivers’ range, currently 50 feet. For now the detector can follow only a single individual, Patwari says, “but we will soon be able to track multiple people or objects and tell the difference between them.” The technology could find applications in fire rescues, hostage situations, and border security."

From PC World's Tech Trends 2010: Predictions for the Year Ahead:

Seeing Into the Future
"Superman's X-ray vision will become a reality. Well, not quite, but close. The University of Utah has developed a way to look through building walls using a network of inexpensive radios. Fire departments will use these to find people inside burning buildings. Police will use them to track down criminals. Shopping malls, subways, sports arenas and other public places will use these systems to determine how individuals move around public spaces."

The Economist - Looking Beyond: Through-the-Wall Vision

Xandem featured media.An article in the October 15, 2009 print edition of The Economist entitled "Looking Beyond: Through-the-Wall Vision" features Xandem's innovative location technologies.

"SUPERMAN had X-ray vision, which was useful for looking through walls when rescuing heroines and collaring villains. But beyond Hollywood, the best that engineers have been able to come up with to see inside buildings are devices that use radar. Some are portable enough to be placed against an outside wall by, say, a police unit planning a raid—and sophisticated enough to show, with reasonable accuracy, the location of anyone inside. But the best models cost more than $100,000, so they are not widely deployed. Now a team led by Neal Patwari and Joey Wilson of the University of Utah has come up with a way to peer through the walls of a building using a network of little radios that cost only a few dollars each.


The ability to “see” people moving around in a building with such a cheap system has many plausible applications, and Mr Wilson has set up a company called Xandem to commercialise the idea. Besides military, police and private-security uses, radio networks might be employed to locate people trapped by fire or earthquake. More commercially, they might be used to measure what retailers call “footfall”—recording how people use stores and shopping centres. At the moment, this is done with cameras, or by triangulating the position of signals given off by mobile phones that customers are carrying. Radio tomography could be simpler, more accurate and, some might feel, less intrusive."
