According to Tang Tai, the principle of a mobile cell phone jammer is very simple: it emits noise waves on the same channel and submerge the communication signals of normal mobile phones and base stations in the noise.
Because the current mobile phones (GSM and CDMA) use digital communication, they have strong anti-interference ability
To forcibly interfere with the communication signals of the mobile phone and the base station, it is necessary to use high-power, wide-channel noise signals (due to The mobile phone itself has a frequency hopping function) to completely cut off the signal between the mobile phone and the base station. "It is extremely unsuitable to use this kind ofprofessional equipment in examination places, because the radiation of this type of equipment is seriously exceeding the standard, which will directly affect the thinking activities of the examinee's brain."
"Last year, during the inspection of the college entrance examination, I received reports that some candidates and teachers were irritable, unable to concentrate, or even headaches in severe cases!" Tang Tai's tone was a bit agitated when it came to the discovery process. These test rooms all use cell phone jammer, and it is harmful to the human body, especially the test takers in the test room are more affected, which will interfere with people's normal thinking."
Speaking of this, Tang Tai is very angry: "When persuasion is invalid, I now strongly oppose using it in the examination room!" He revealed that even a researcher in his own laboratory, working in a similar environment all year round has a certain degree of resistance. However, if you stay for half an hour under microwave radiation of this intensity, you will still experience mild headaches, irritability, and inability to concentrate.
The potential health risks of using cell phone jammers, especially in environments such as exam rooms, where people are exposed to microwave radiation for long periods of time. While the principle of cell phone jammers is simple—emitting noise waves to interfere with communication signals—it is critical to consider their unintended consequences, especially the impact on human health.
Concerns about excessive radiation exposure from cell phone jammers are not unfounded
Adverse effects reported by test takers and teachers during the college entrance exam include irritability, difficulty concentrating, and headaches. These symptoms can seriously impair an individual’s ability to perform effectively in high-stakes situations such as exams, ultimately undermining the integrity and fairness of the assessment process.
In addition, Tang Tai’s personal experience in a laboratory setting highlights the pervasiveness of microwave radiation and its potential impact on cognitive function and health. Even people who are accustomed to working in similar environments can experience mild discomfort symptoms and cognitive decline after prolonged exposure to high-intensity radiation.
Given these concerns, Tang Tai strongly advises against the use of cell phone jammers in exam rooms and other sensitive environments. He recommends not resorting to potentially harmful jamming methods, but exploring other ways to address the issue of unauthorized cell phone use without compromising an individual’s health and well-being.
Tangtay's position highlights the need for increased awareness and regulation of the use of cell phone jammers, particularly in settings where personal cognitive function and performance are critical. By prioritizing human health and safety, educators, policymakers, and administrators can ensure that measures to discourage cell phone use remain effective while minimizing potential harm to individual well-being.
