Cell phone jammers to limit and disrupt communication in various situations

There are many reasons for using a cell phone signal jammer. With the permission of the local government, some of them can be used legally. Mobile phone jammers are usually used in places where mobile signals are blocked and cannot ring due to security reasons or due to forced mobile muting.

A cell phone jammer is an instrument that prevents a cell phone from receiving signals from a base station. When used, the jammer effectively disabled the phone. These devices can be used in almost any location, but are mainly located where the phone will be particularly disturbing because people want to keep quiet.

When the mobile phone jammer is active, most mobile phones will not display network signals, and when the GSM jammer is turned off, the mobile phone will also be active. Mobile phones use unique frequencies to speak and listen. Most cell phone jammers block one of these two frequencies, which indirectly produces the effect of blocking these two frequencies. Mobile phone jammers work on the same principle as jammers that prevent radio communications. They work by interrupting the frequency from the cell phone to the base station or from the base station to the cell phone.

Law enforcement agencies and the military use cell phone jammers to limit and disrupt communications in various situations. Some companies use cell phone portable jammer to prevent corporate espionage by blocking communications in sensitive areas. Some people also use portable cell phone jammers to prevent others from using the cell phone in their vicinity.

Can the driver be prevented from speaking on the phone? New jammers made by Indian engineers can disable the driver ’s mobile phone while the driver continues to talk or text, thus allowing the driver to make a decision.

According to Smithsonian Magazine, the system uses RFID (radio frequency identification) technology to track whether the driver is trying to use a mobile phone in a moving car. This triggers the jammer to stop the driver ’s phone, which is a more effective measure than the smartphone application that needs to be installed on the criminal ’s phone.
