Through-Wall Tracking With Wireless Networks (with description)

Joey Wilson and Neal Patwari of the University of Utah describe and demonstrate their through-wall wireless network tracking system. Joey enters a home surrounded by simple radio devices. He does not carry any kind of electronic device on his body, nor are any devices deployed inside the home, and the system is able to estimate his location.

Where's the dog?

[DoughyWilson]

We locked the dog in the kitchen area while we tracked. Small animals don't disturb the signal strength as much as a human, so they probably wouldn't show up much in the imaging. We'll have to look into that in more detail later.

No scam at all! This is all perfectly plausible.

You can broadcast (or use existing broadcast RF signals) to detect movement, I've experimented with this myself quite a bit, so I know what he is doing is very real! Much more accurate than my stuff, but very possible.

Anyone of you guys who doubt this should remember your "Analog TV & radio days", remember that when you walked past your ANTENNA...that you could see a change in your TV or Radio signal? That is the very same technology.

the new world order will love this it will go great with the pre-crime laws

@DoughyWilson What software did u use to visualize the position of the person?? i really would love to know please.

Could you track multiple levels like upstaires and down stares on the same kind of setup

[Tokamak85]

I saw the Senior project presentation for this last year, very cool stuff. It will be an excellent system when it is further developed!

[sshzp4]

Oh and do your sensors know their positions relative to each other? Or is that something you input manually?

[sshzp4]

hmm, pretty cool stuff. But.. isn't that a lot of sensors that you use? What about accuracy attrition per sensor reduction? The post-proc was not in real time (plot reminds me of matlab), or was it? How about multiple moving objects, can you track both at once, even if path intersection occurs? Articles from this? Post that on the info section please. Good job!

[BWAlucarD]

aah ok! thanks... that was something i've asked myself for a long time now^^

[Khaluless]

well next time I see a butt-load of phones surrounding my house I'll quit doing all my illegal activities STAT!

[fuxxfuxxfuxx]

Ahem, this looks much like my new invention - i call it "window"... the demo would be quite more impressive without this frigging GLASS-HOUSE he is walking in...

[CuervoBlack06]

This is just a prototype of course it's going to be unrealistic to put out all of those transmitters. As technology advances they will get smaller and smaller so as that you can just throw them onto the property like if they were in orbs like golf balls or ping pong balls etc. Instead of just placing them one by one and risking hostages lives and their own.
