At present, domestic signal jammers are not unable to shield 5G signals, but some types of shielding instruments have not achieved full coverage of 5G commercial frequency bands. This problem is related to the incomplete coverage of the current Cell Phone Blocker For Warehouse Size band. For example, the 5G frequency band of the mobile phone is 2.6G, which is the same as its existing 4G frequency band, so even the old jammer should be able to handle it in theory. However, China Telecom Unicom's 5G frequency band 3.5G is indeed far from the two 4G frequency bands. If you use the old model cell phone jammer , there is indeed a possibility that it cannot be shielded. In order to prevent such cheating incidents from happening again, the most reasonable solution is to develop signal jammers with stronger shielding ability and more comprehensive shielding frequency bands. In addition, it is also important to purchase qualified products from regular manufacturers. But is this the core of the problem?
Why can the mobile phone be brought into the examination room, why can I take out the mobile phone in the examination room to get the test paper, and why can I take out the mobile phone and get the test paper in the examination room? These are the crux of the matter! Don't avoid focusing on what's most important, discussing only the technology, avoiding or even ignoring human factors like poor oversight, poor organization, etc. This is the greatest trampling on public opinion. Many schools are very busy recently, because the days of the college entrance examination are counting down day by day. They are non-stop to prepare the materials and machines needed for the examination room. This is to allow candidates to take the exam in a stable and orderly environment. This is also the responsibility of the school. So recently we can see a kind of machine installed in the examination room. This is a Cell Phone Blocker For Warehouse Size that is being promoted by many schools recently. This is a problem that can effectively counteract the cheating of electronic signals. Although so effective, one thing that is not known is that,
