Contraband Cell Phones in Prisons [PDF ebook] 
Technology Solutions and Perspectives

Just as consumer demands for mobile devices have risen rapidly, the use of cell phones by prison inmates has grown as the U.S. prison population continues to expand. This use is considered contraband by prison officials. The number of cell phones confiscated by prison officials has dramatically increased in only a few years. This increase in unauthorized cell phone use by inmates is a mounting concern among correctional administrators across the country. This book investigates and examines wireless technology solutions to prevent contraband cell phone use in prisons, such as jamming, managed access, and detection.
