How to properly equip standardized examination rooms with test room signal jammers?

The issue of students using mobile phones to cheat during the college entrance examination has sparked widespread discussion, with people questioning whether there are handheld metal detectors and signal jammers in the examination room, and why mobile phones can still be brought into the examination room to send text messages.

The problem lies not only in the security measures of the examination room, but also in the potential loopholes of the technical defense equipment. Standard examination rooms are equipped with necessary tools such as examination room WiFi jammers, metal detectors, and wireless signal detectors. However, if the jammer is installed, the mobile phone can still send text messages, indicating that the signal jammer may not be able to effectively block the communication signal. It may be that the nearby communication base station is close, and the signal shielding is not sufficient, causing indirect interference.

When purchasing a signal jammer for the examination room, it is crucial to choose the latest 5G version of the cell phone jammer. These updated jammers should cover a wide range of signal frequency bands, including 2G, 3G, 4G and 5G, as well as WiFi 2.4G and WiFi 5.8G wireless signal bands. This comprehensive coverage ensures that the shielding effect is strong and effective. In an environment with strong communication signals, a more powerful signal shielding device may be required to achieve the best results.

Therefore, when purchasing a 5G jammer for a standardized examination room, it is recommended to look for a reputable brand manufacturer to ensure excellent shielding effect. This practice will help create a fair and favorable examination environment.
