Is the mobile phone signal jammer harmful to the human body?

In today's society, whenever we have large-scale exams or other exams, we will use mobile phone signal jammers. Then some people may be worried about whether the jammer has any effect on the human body? Then I will give you an answer.

First of all, we must face the signal jammer rationally and scientifically. The working principle of the jammer is to send out a specific signal to shield or interfere with the signal between the mobile phone and the base station, so that the mobile phone has no signal or cannot find network services. Text messages sent and received by mobile phones will also become garbled, so the original message cannot be recognized.

But in this process, it does not rely on the unlimited increase of power to compete with the mobile phone base station to achieve the blocking effect. The electromagnetic signal strength from the mobile phone signal jammer is very weak. As long as it is a qualified product produced by a regular manufacturer, its electromagnetic radiation intensity can pass the strict inspection of the "China Centers for Disease Control and Prevention Institute of Environmental and Health Related Product Safety" and other national authoritative testing and certification agencies, and the electromagnetic field intensity measurement values ​​of all sampling points They are all lower than the relevant frequency band standard limits set by the State Environmental Protection Administration, and are not harmful to the human body. Therefore, there is no need to panic. Unnecessary psychological burden is the real obstacle.

Secondly, the power of the mobile phone signal jammer is very small, and the range is only 20 to 30 meters. Will not cause interference to mobile phone base stations at all. Moreover, when used in specific occasions, it will undoubtedly endanger the security of public information. The frequency of the electromagnetic signal it sends falls completely within the working frequency band of the mobile phone designated by the country, and the signal is always in a relatively static and constant state, so conventional mobile phone signal interference will not affect any other signals. Electronic equipment. It will not interfere with people's brains, nor will it affect people's normal thinking.

So the above is the answer to whether the mobile phone signal jammer has any effect on the human body, please rest assured and treat the jammer rationally and scientifically.
