How GSM and 4G signal jammers work

GMS and 4G jammers are devices that can jam the signal of cell phones. Suppressing mobile communications is an effective way to protect confidentiality at a business meeting, during negotiations. A stationary cell phone jammer is often installed at commercial facilities, at schools during examinations (4G jamming on the exam is especially common), in theaters and other facilities where a powerful and prolonged blocking of communication is required.

To protect themselves and their personal data from unlawful interference from other people, and at the same time from annoying telephone chatters who are not familiar with the rules of behavior in public places, people have invented 4G signal jammers, also known as GSM frequency jammers. If you suspect that someone is following you using covert surveillance systems, audio and video equipment to record your personal meetings and conversations, or hidden cameras and microphones to monitor you, then you need to install a GSM 3G jammer. This signal jammer will help you get rid of many types of tracking and surveillance used by people watching you. In order to make yourself even more secure, you can also use WiFi signal jammers and VHF UHF blockers along with suppressors of other, not so common, but still used frequencies.

The purchase of GSM jammers for personal safety and within your private property is completely legal. However, it is worth remembering that you have no right, using various means of suppression, to prevent the use of communication services by third parties in public places.


How to block GSM and 4G signal on cell phone?
Before using for the first time, the antennas must be tightly screwed to the corresponding connectors on the body of the phone jammer. The built-in rechargeable battery must then be fully charged for several hours. A portable cell phone jammer can work autonomously for about 2 hours from one battery charge, while if you connect the jammer to a charger, it can work continuously.
