Cellphones in jail? Not with this technology

Cincinnati-based Cell Command Inc. successfully tested its beacon system for shutting down contraband cellphones in prison by deploying the system at the Hamilton County Justice Center. “We turned the beacons on, and the phones shut themselves down,” said John Fischer, who developed the patented technology and hopes to build a multi-billion dollar company around the idea. “We knocked down every single phone we tried to knock down within a very short time period, anywhere from one to five seconds upon boot up.”
