Nowadays, the examination has come to an end, but every year, the content of "taking mobile phones into the examination room to release the examination" has aroused heated discussion. The public is talking about whether the examination room is equipped with handheld metal detectors and signal jammers? Why can you bring your mobile phone into the examination room and send messages with your mobile phone?

The emergence of this problem, in addition to the security problems of the examination room, there may also be some loopholes in the technical defense equipment of the examination room. Signal jammers, metal detectors, wireless signal detectors and other equipment are essential equipment in the standard test room. If the test room is equipped with jammers and mobile phones can still send messages, the signal jammers may not effectively shield the communication signals. This may be caused by the poor shielding of the signals due to the proximity of the accessory communication base stations, or the indirect shielding of the signals, or the signal jammers may not update the latest 5g version signal jammers. The latest 5g Mobile Phone Signal Jammer must be selected when purchasing the signal jammer. The latest 5g Signal Jammer must include 2G, 3G, 4G, 5g signal bands and WiFi 2.4G, WiFi 5.8 wireless signal bands, so as to achieve good shielding effect. If the environmental communication signal is relatively strong, it is necessary to use a higher power signal jammer to achieve a good shielding effect. Therefore, when purchasing 5g Mobile Phone Signal Jammer in standardized examination room, we must identify a good brand manufacturer to ensure better shielding effect and create a good fair and just examination room environment.
