"The German federal government is preparing a law that would allow the use of mobile phone jammers during major events, and in prisons. Blocking the use by criminals of mobile phones is seen as an important counter-terrorism weapon. By transmitting on the same radio frequencies as the mobile phone, a phone jammer can effortlessly stifle annoying chatter in movie theatres, at funerals or in hospitals. However, in many countries, including Germany, the technology is officially illegal. Phone jammers not only disrupt licensed services operated by the mobile carriers, but also other services operating in adjacent bands."
