Will the untimely ringing of the phone in a movie theater or a concert quickly make people remember it? In any case, this is what Patrick Devedjian, the Minister of Industry, wants. On October 10, he issued a decree authorizing the installation of " cell phone jammer " to make cell phones in theaters and movie theaters unusable. According to him, this diagnosis requires "necessity": the installation of a mobile phone jammer is to prevent the mobile phone from being picked up at school. Without the network, there is no communication, for any purpose. Philippe Meunier believes that teachers can "declare that they will get the same respect and benefit from the viewers or actors in the entertainment venue" and ask Vincent Peillon if it can" Authorize the manufacture of mobile phone jammers in schools, just like in theaters and movie theaters."
