Signal phone jammer
Cell phone jammers, also known as cell phone blockers or jammers, are devices that disrupt radio connections such as cell phone networks, WLAN or GPS by emitting radio waves. The range is between 10 and 40 meters.
The military and government even have models that can jam radio signals for miles.
Retailers can use jammers to prevent you from comparing prices in-store. This could potentially increase retailers' sales.
In certain rooms where quiet is desired or where distractions are to be avoided, jammers can also be useful. In this way, ringing mobile phones can be prevented during a cinema performance or young people chatting in schools.
But criminals could also use jammers to disrupt wireless alarm systems and other radio connections and prevent an emergency call being made via the mobile network.
