Are jammers different in different environments?

Are jammers different in different environments?

  • 2023-01-08

In the current examination, there are always people who want to cheat by using special means, and these means need communication equipment, which can not be separated from signals. And the signal jammer, as its name implies, is aimed at the signals used by some communication devices to interfere with them or make them ineffective.

Most signal jammers use segmented cut-off signals, which are converted one by one. But this kind of equipment can transmit multiple signals at the same time. The signal is stable and can interfere with 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 field will become more and more accurate in the future.

However, if we do not use the signal jamming equipment correctly, the interference effect will be poor, and an examination room accident may occur. Its interference effect will be different under different on-site environments. This is related to the site conditions. When there is a building block, or when the distance between the base station and the signal source is close, the signals received by different mobile phones will be more or less different, so it is very important to detect the local signal frequency band. At present, the signal jammer has become one of the necessary tools in the examination room to strictly prevent examinees from cheating through scientific and technological means, and to protect the information security in the examination room.
