The college entrance examination season is coming soon, and our examination room layout work has been carried out one after another. At this critical moment, our parents and teachers always worry about whether the anti-high-tech cheating tools used in the examination room will have an adverse effect on the health of the candidates? Among them, mobile cell phone jammer have become a hot spot for everyone. As a well-known manufacturer of mobile phone signal jammers in China, Foshan Linchuang Technology will answer this question for you.
First of all, we must take a rational and scientific approach to the mobile phone signal jammer. The working principle of the mobile phone signal jammer is to send out a specific signal to awaken or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or cannot find the network service. The text message sent and received by the mobile phone will also become garbled. Therefore, the original message cannot be recognized.
However, in this process, the barrier effect is not achieved by unrestrictedly increasing Power and competing with mobile phone base stations. The intensity of electromagnetic signals emitted by mobile phone signal jammers is very weak. As long as qualified products produced by regular manufacturers, their electromagnetic radiation intensity has passed the strict inspection of the national authoritative testing and certification machine, such as the "China Center for Disease Control and Prevention Environmental and Health Related Product Safety Institute" , The electromagnetic field intensity measurement values at all sampling points are lower than the relevant frequency band standard limit of the "Electromagnetic Radiation Protection Regulations" (GB8702-88) formulated by the State Environmental Protection Administration (this standard is only 1/5 of the European standard and 1/ of the Japanese standard) 10) It will not cause harm to the human body, so there is no need to panic. The unnecessary psychological burden is the real obstacle.
Secondly, the Power of the mobile phone signal jammer is very small (≤1W), and its range is only 20 to 30 meters. It will not cause interference to the mobile phone base station at all. Moreover, when it is applied in specific occasions, there is no question of endangering public information security. The frequency of the electromagnetic signal emitted by it falls completely within the working frequency band of mobile phones stipulated by the country, and this signal is always in a relatively static and constant state, so a regular mobile phone signal jammer will not affect any other electronic equipment. Will not interfere with people's brains and affect people's normal thinking.
