X-ray vision is a staple of sci-fi films and comic books and now researchers have turned this concept into a reality.
Using
a wireless transmitter fitted behind a wall, computer scientists have
developed a device that can map a nearby room in 3D while scanning for
human bodies.
Using
the signals that bounce and reflect off these people, the device
creates an accurate silhouette and can even use this silhouette to
identify who that person is.

Wonder how much this will cost per ft^2?
To an extent, it can be done right now using the wireless signals from your phone, router and any other wireless device you own. Just not 'that' public yet.
Indeed. Why do you think the analog to digital push was so heavy? Analog devices cannot transmit high speed data, have a variable wave form along amplitude and frequency, and have too much noise that accumulates as the signal traverses the network. Digital signal is much simpler. It's a series of discrete pulses, 1 bits and 0 bits. Digital is easier to reproduce as well. It uses signal regenerators. The digital handles all of the connections needed to basically plug your entire house up to the internet, which in turn could allow for more monitoring of your activities. We are all plugged into the matrix, and that was the goal. Offer all these cool new whiz bang tech gadgets to simplify the surveillance process. Boy that was easy wasn't it? Not that people would rush to jump on board with being constantly monitored through their electronics or anything... You can use a jammer, but be prepared to deal with the FCC. They don't like competition when they are walking all over someone else's signal or snooping on someone. We've got to keep that "emergency traffic" unobstructed, just in case you need an ambulance. Dont ya know? ;)
