Electronically jamming everything from specific cell phones, satellites or any other communications device is the goal of a prototype system military scientists at Defense Advanced Research Projects Agency want to build. Known as the Precision Electronic Warfare (PREW), the goal of the technology and its algorithms will be able to surgically disable targets in small areas on demand without hindering or disabling friendly devices in the surrounding area. DARPA said it envisions two modes of operation for a PREW system: point-to-an-area and point-to-a-spot. The first would target very specific communications devices while the latter would disable an entire region.
