Where are signal jammers used?

  • 2022-07-10

With the continuous development trend of science and technology, the popularity of mobile phones supporting 5g communication is rising rapidly. While 5g technology is convenient, we should pay more attention to the problem of data leakage with 5g mobile communication technology. Especially in some places where the use of mobile phones is prohibited, such as secret related organs, scientific research institutions, detention centers, college entrance examination halls and other unique places, more regulations have been made on the technical nature of mobile phone signal shielding. In order to ensure that these places will not have a negative impact due to the use of mobile phones, it is necessary to select signal jammers to shield mobile phone signals. Nowadays, mobile phone detection and shielding work have eliminated many potential safety hazards that disturb discipline for key venues, such as examination venues, so that when students enter the examination venue, they can ensure that no communication equipment can be brought into the examination venue. Even if they are lucky enough to enter the examination venue, they cannot communicate or surf the Internet normally, so that all students compete under fair and just conditions.

The principle of signal jammer is not very difficult. As a mobile communication technology machine and equipment, mobile phones must first establish a connection with the surrounding communication base stations, and then connect the base station equipment to find the communication arrival station. In the whole process above, all information content is installed and transmitted according to radio waves. The commonly used radio frequency band of mobile phones is spread over the range of 850-4900mhz. The Signal Jammer only needs to be aimed at this frequency range to achieve the purpose of shielding.
