Wireless Network Modded To See Through Walls 161

KentuckyFC writes "The way radio signals vary in a wireless network can reveal the movement of people behind closed doors, say researchers who have developed a technique called variance-based radio tomographic imaging which processes wireless signals to peer through walls. They've tested the idea with a 34-node wireless network using the IEEE 802.15.4 wireless protocol (the personal area network protocol employed by home automation services such as ZigBee). The researchers say that such a network could be easily distributed by the police or military wanting to determine what's going on inside a building. But such a network, which uses cheap off-the-shelf components, might also be easily deployed by your neighbor or anybody else wanting to monitor movements in your home."

    Horrible, a piece of technology could be abused if used in a certain way by evil and nefarious bad guys. We'll have to ban this wireless technology just in case they're out to get us. Breakout the crowbars, put on the night vision goggles, prep the bolt cutters for backup and defend yourself with the glass cutter before they break in. Tinfoil hats to the rescue!

    Discerning the physical location and movement of an object with radio waves, what can we call such a thing?

    Ahh, yes, Radar...

    While I agree with your last statement, I do have to wonder about your idea of common courtesy. My wife and I usually close the window.

    Talking about dysfunctional, though, it seems strange that your kid feels the need to turn up the stereo. I still can not believe that the thought of your own parents having sex is 'icky' to people without something having gone wrong in their sexual upbringing (and I, too, find the thought of my parents having sex 'icky', make no mistake).

    In our household, sex is discussed very openly today and I sure as hell won't change that just because kids have taken over the house ;).

You will lose an important disk file.
