Wireless Network Modded To See Through Walls

Posted by CmdrTaco on from the still-can't-see-through-pants dept.

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."

  1. Fear mongering by skornenicholas · · Score: 5, Funny

    Went straight for the "everyone is spying on me!" ploy a little quick there. Seriously, if anything my neighbors request to see LESS of my movements. This may be due to the fact that I have a clear shower curtain and my bathroom doors lines up to a big bay window facing the road...took me two months to realize that one.

    And imagine the teens' surprise and horror when they discover their parents aren't "sleeping" at all...

    What with three wireless hubs, an RFID scanner, and half-a-dozen Bluetooth devices always on, I'm pretty sure I'm already casting EMF shadows on my walls.

    Been seeing some really big spiders, too...

  4. Seymour Hersh hinted at this a few years ago by mantis2009 · · Score: 5, Interesting

    Investigative reporter Seymour Hersh said that the U.S. military had developed a secret new technology for use in urban warfare. He said the technology was revolutionary, equivalent to the first time tanks were deployed on the battlefield. From what I remember, there was speculation that Hersh had learned that the military could now see through walls.

    Which means they'll want WiFi access on the porch, the back yard - the patio and the sundeck.

    I think you mean the front observation deck, the firing range, and the snipers nest.
