Wireless Network Modded To See Through Walls
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."
wanting to determine what's going on inside a building.
Now when teens want to sneak out at night, they can easily see thru walls if their parents are sleeping!
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.
Looks like it is time to get hold of some Aluminum Oxide paint.
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...

Step 1:Paint your house with it.
Step 2: Install a Faraday cage in the dungeon *ahem* basement.
Step 3: ??????
Step 4: Privacy!!!!
"It's ok, I'm completely secure as long as my iron is off"
Terribly thin floors & cielings mean that I can monitor where my upstairs neighbor is and what he is doing at all times.
Of course my neighbors can monitor when I have sex and how good it is, but I kind of get off on that anyway...
Up, down, up, down, what the heck are they doing?
You owe me a new mind's eye, I had to poke it out to get rid of that mental image.
It's called a window.
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.

Maybe he only showers every two months?

Another advantage of living in the country.
If someone is within 1 km of my house (and I doubt this system has that kind of range) the dogs and various livestock alert me WAY before that person can see my movements. And those movements will be important to that person at this point. Especially the "cocking the shotgun" movement.

The trick is to imagine the poster as a hot 19 year old chick, who refers to herself as a guy because she's a lesbian.
Is 1563649 a prime number?
