In France, according to the law, cell phone jammer can be used free of charge in theaters, so theaters are also defined as places in their specific layout that allow the display or dissemination of thought works to the public, explicitly designated in cinemas, operas and theaters you can install and use a signal disruptor.
Cell phone disruptors are also suitable for other places, such as stadiums, museums, etc. Of course this is not all. The owner of a bar or restaurant who is responsible for music playback may also install a phone disruptor. His sound device is a specific layout for playing music to the public and therefore requires the right to install the jammer. School teachers prefer to install signal jamming equipment in the classroom so that children can learn better without worrying about students playing mobile games in class.
