It's easy to buy devices over the Internet that will jam wireless signals for cell phones, GPS signals, Wi-Fi systems, and more. Jammers work by flooding an area with noise that covers the radio bands to be jammed. Since these are inexpensive devices that are not approved by the Federal Communications Commission (FCC), they often broadcast noise in other bands. A US cellular band is adjacent to the 800 MHz band where Nextel, some public safety, government and business systems are deployed, so it is likely that these signals will be scrambled to the target bands.
Jammers are used in schools, restaurants and other places where homeowners want to prevent people from making and receiving phone calls when they are inside. Lately, prisons have started to consider deploying jammers to prevent their inmates from using cell phones in prison. It's illegal to have a cell phone inside a prison, but again, that doesn't seem to prevent inmates from owning them.
