Application of Vehicle Electronic Jammer

Application of Vehicle Electronic Jammer

Who is the vehicle electronic jammer? Today, let's trace the history of this artifact.

At the beginning, the vehicle electronic jammer was not actually set up for the test scene. The original application is actually prison.

In order to ensure the information security and privacy of the prison's high wall compound, it is necessary for the prison to isolate the communication signals between the prison and the prison, which is the original intention of the vehicle electronic jammer.

When the vehicle electronic jammer was first invented, the whole world only developed into the 2G era. At that time, although there were three operators in China, in fact, mobile phones used the second generation network communication technology. The communication frequency of mobile phones used by manufacturers of different systems is quite different.

The mobile phone can make and receive calls mainly depending on the support of the communication base station. After the phone is turned on, it will actively connect to the nearest communication base station, and the communication base station will command when making and receiving calls. In fact, it is the communication with the communication base station. What should the prison do if it wants to interrupt the communication between the prisoners inside the prison and the outside world?

The answer is very simple. It only needs a machine with the same frequency as the mobile phone to make noise. In this way, when the base station tries to connect to the mobile phone. It will be found that the signals coming from the mobile phone are too complex to recognize, so they will refuse to communicate with the mobile phone.

Based on this principle, after the vehicle electronic jammer was developed, everyone was happy. The prison only needs to be equipped with a few jammers that can emit such noise to interfere with mobile phone communications throughout the prison. With the increasing number of scenarios requiring interference signals. The vehicle electronic jammer originally designed for use in prison has gradually entered the normal commercial scene, such as important meetings and examinations.
