Function and application of mobile phone jammer

Function and application of mobile phone jammer

  • 2022-08-07

Now there are special mobile phone jammers in exams, but some people want to use some means to cheat, and even look for loopholes at all costs. So, what role can mobile phone jammers play in the examination room? Will there be any vulnerability when using this device?

The previous signal shielding equipment used to cut off the signal in sections, and the signal was converted one after another. However, this kind of equipment can transmit multiple signals at the same time. The signal is stable and can shield a long distance. Therefore, don't take chances. Now the technology is more and more developed, and the products produced by many companies are more and more advanced. With the development of science and technology, I believe that the equipment in this area will only become more and more accurate in the future.

Mobile phone jammer is a necessary tool in the examination room to prevent candidates from cheating through scientific and technological means and to protect the information security of the examination room. However, if we do not use the signal shielding equipment correctly, the shielding effect will be poor, and the examination room accident may occur. In different use sites, the effective shielding range will be different. This is closely related to the signal field strength at the site. The shielding range of different mobile phones in the same site is not necessarily the same, so it is very important to detect the local signal frequency band. The factors that can affect the shielding range include but are not limited to: the distance from the base station, the orientation, the presence or absence of obstacles, the wall material of the site building, the installation height and the installation specification of the shield, etc. it is best to comply with the manufacturer's requirements.
