Encyclopedic overview
Radio jamming is the deliberate blocking of or interference with wireless communications. In some cases, jammers work by the transmission of radio signals that disrupt telecommunications by decreasing the signal-to-noise ratio.
The concept can be used in wireless data networks to disrupt information flow. It is a common form of censorship in totalitarian states, in order to prevent foreign radio stations in border areas from reaching the country.
