Schools should follow these three standards when applying signal jammers:
Wireless communication management method
1. The application of signal jammer cannot be obtained by giving up the cost of mass mobile communication technology.
Among the people who use cell phone signal jammers, some do it to avoid cheating in exams, and some do it to keep the venue quiet or keep the conference confidential. These are all out of good wishes and purposes. But there are also reasons for self-interest. For example, homeowners who operate public phone booths are very likely to use jammers to affect mobile communication towers near their operating locations, so that people working near the public phone booths they operate can use their mobile phones. It is not easy to use, so it is changed to a public phone booth for voice calls to increase its own economic benefits. In addition, the three major mobile operators are also likely to use jammers to harm the rights and interests of each other, so that they can gain an advantage in the competition among peers in some departments. In addition, mobile phone signal jammers are also very easy to be added to mobile phone software and turned into a veritable monitoring device.
The above examples are the purposes for which we use cell phone signal jammers, but no matter what the purpose is, it should not be obtained at the cost of giving up mass mobile communication technology. In fact, based on scientific research, it is possible to install a mobile phone signal jammer without affecting the normal use of mass mobile communications. There are three reasons why cell phone signal jammers disrupt mobile signal tower signals:
First, the user of the mobile phone signal jammer did not pay attention to the communication needs of the Smiling Man at all, and the function target was wrong. It should have limited the mobile phone communication of a small group of people (such as students), but expanded the target to other nearby general groups.
Second, the operation method is unreasonable. Because the installation position of the mobile phone signal jammer is unreasonable or its signal strength setting is too large, it should be operated within a small range but is not operated well.
Third, the purchased mobile phone signal jammer does not comply with the wireless communication equipment approval standards, the output power exceeds the standard, or is a shoddy and substandard product. Choosing the right reason, in order to avoid its impact on mobile communication signals, is actually very simple: first, use qualified products produced by reliable manufacturers, and secondly, choose the installation location and function direction well. , The third is to set an appropriate signal strength and limit the signal sent to a small, closed range. As long as the above three points are ensured, the damage to surrounding mobile communication signal towers can be reduced to a minimum level.
2. Improper use of mobile phone signal jammers in schools may cause unnecessary damage to the body.
Theoretical analysis shows that when the mobile phone signal jammer is working, if the setting is unreasonable and the signal strength is too high, in a small closed space such as a conference hall or a classroom, the radio waves will be lost in the narrow space. Accumulatively, through multiple reflection surfaces from walls, ceilings, and roads that are originally separated from the outside, people in the room will be exposed to severe electromagnetic radiation. According to the survey, the college entrance examination, junior high school and high school are the places where mobile phone signal jammers are most used. However, in some examination rooms where mobile phone signal jammers are used, some defendants (college entrance examination inspection staff, students and teachers) become upset and lose energy. Due to the concentration of law and other situations, some students even suffer from headaches. Many signs indicate that if the signal strength of the mobile phone signal jammer is turned on too high, it will seriously affect the normal thinking of students in the examination room.
As we all know, the characteristics of electromagnetic waves spreading freely in the air. While cell phone signal jammers can achieve their limited purpose of blocking mobile signal tower signals in a special area, they can also harm human health to varying degrees. , so use cell phone signal jammers with caution.
3. Responsibility management methods Units should increase the scope of control and standards
In response to the increasing use of mobile phone signal jammers by people from all walks of life, departments such as the wireless communication management and security bureau must increase the scope of control and standardize the use of mobile phone signal jammers.
