What do you need to know before choosing a cell phone jammer?

  • 2022-05-27

Near June, major universities are preparing for the college entrance examination. Many schools choose cell phone jammers to prevent students from cheating using devices such as mobile phones. So how to choose correctly and avoid some unnecessary problems.

First of all, it is necessary to estimate the area to be shielded on the spot and test the shielding distance of cell phone jammer. Do not only use the network test of a certain business provider, but try it several times. During the exam, cheating candidates use different mobile networks. There are many 5g mobile networks. If the power of some signal shielding devices is not enough, they may not be able to shield the network completely. This is the difference between the models of shielding equipment. The parameters set by different shields are different, and the application environment is also different. Be optimistic about the installation location in advance and communicate with manufacturers in advance to reduce uncertainties and ensure greater role.

In the examination, using cell phone jammer to manage students' examination is indeed a more effective method. However, the shielding effect of signal shielding equipment often depends on whether electronic products can receive and release signals and the strength of on-site signals. When purchasing signal shielding equipment, repeatedly verify its shielding effect and long-term stability in combination with the situation at that time. In order to ensure the quality of signal shielding equipment, it is necessary to purchase.
