Celldar
Availability: 3-10 years.
Cellphones emit microwave radiation at similar wavelengths to radar systems. Celldar is a passive radar system that listens to the signals reflected by cellphone emitters. When a solid object passes between a transmitter and a cellphone it reduces the signal strength at a receiver.
Celldar was originally designed as a military system that would use reflected cellphone emissions to locate aircraft passing above the protected area. However, by correlating signal strength across a wide number of cellular transceivers (both base stations and phone handsets) in real time it should be possible to build up a picture of what objects are in the vicinity. Subtract the known locations of buildings, and you've got a system that can place any inhabited area under radar surveillance -- by telephone. (As Rodney King demonstrated, we can already be tracked by cellphone. Now the panopticon society can place us under radar surveillance by phone. And as phones exchange data at ever higher bandwidth, the frequencies will shorten towards the terahertz range. Nude phone calling will take on an entirely different meaning ...)
