If there is a necessity to avoid information leakage, eliminate interference with other equipment, or maintain silence in certain areas, the best solution is the purchase of GSM jammer.
Cell phone jammer or GSM (Global System for Mobile Communications) jammer is an appliance, which is used to block a signal of cell phones.
How Do Signal Jammers Work
• Faraday cage principle
• Radius signal blocking technique
When it comes to the Faraday cage principle it means that a mobile jammer is framed with special panels, which are made of metal. These panels passively block any signals. Such a construction of a jammer is considered to be the simplest one.
The second way of the GSM blocker functioning implies a more complicated mechanism. Thus, a phone blocker, which is aimed at the radius signal blocking, can detect the presence of an active phone signal within a defined territory. Any cell signal within a certain radius is jammed upon identifying any call attempt. Such a device can make a phone go into standby mode.
