Perfectjammer 2022/05/13

The 2022 exam season is coming. For the major exam rooms, there is a piece of news from last year that needs the most attention: "A candidate in Huangpi District, Wuhan, Hubei Province, suspected to have uploaded a photo of a mathematics paper for the National College Entrance Examination to the APP to search for answers. "And the reason for this was that there was a loophole in the Does Cpr Call Blocker Work On Cell Phones blocking, which allowed the candidate to upload the test questions on his mobile phone. The 2G/3G/4G/5G network frequency bands we use every day are all stipulated by the state. The mobile phone and the base station must use the specified frequency band for normal communication. In the past two years, with the breakthrough of communication technology, 5G technology has been widely used. However, the signal jammers in some examination rooms have not been updated in time, which has caused such a big omission. Therefore, the examination room should update the Cell Phone Jammer in time, and use a more professional and comprehensive mobile phone shield to achieve the shielding effect.

Exam rooms, prisons, and detention centers often use Does Cpr Call Blocker Work On Cell Phones to prevent people from illegally using mobile phones. Signal jammers block mobile phone signals by interfering with the downlink signal of the base station. The principle of mobile phone signal jammers is that the frequency emitted by the jammer itself interferes with the mobile phone receiving base station. The normal frequency of the mobile phone prevents the mobile phone from being able to connect to the base station, making it impossible to make calls, send and receive text messages, and surf the Internet normally. As a kind of interference device, whether the electromagnetic radiation generated by the cell phone signal jammer will harm human health is also a problem that people are more concerned about. While the cell phone signal jammer shields the cell phone signal and ensures information security, it will also have some negative effects. The problem of mobile phone signal jammers will generate some radiation, but the radiation is very low, and it will not have adverse effects on human health.
