Schools should follow these three principles when using mobile phone signal jammers

radio management

1. The use of mobile phone signal jammers should not be at the expense of public mobile communications.

Among those who use cell phone signal jammers, some do it to prevent cheating in exams, and some do it to keep the venue quiet or to keep meeting information confidential. These are all out of good intentions and purposes. But there are also those who do it for their own selfish interests. For example, a household owner who operates a public phone may use a jammer to interfere with the mobile communication base station near the location where he operates, so that people who work near the public phone they operate cannot use their mobile phones and use them instead. Make calls on public phones to increase your economic income. In addition, mobile communication operators may also use jammers to harm each other's interests and gain advantages in certain local competitions in the same industry. In addition, it is easy to add software to the mobile phone signal jammer and become a veritable eavesdropper.

The above listed are the purposes for people to use mobile phone signal jammers, but regardless of the purpose, it should not be at the expense of public mobile communications. In fact, according to research, it is possible to install a mobile phone signal jammer without affecting the normal use of mobile communications by the public. There are three reasons why mobile phone signal jammers disrupt mobile communication base station signals:

First, users of mobile phone signal jammers do not take into account the communication needs of outsiders at all, and target the wrong target. They should restrict mobile phone communication to a small group of people (such as candidates), but instead expand the target to other ordinary people in the surrounding area.

Second, the use method is improper. Because the cell phone signal jammer is installed in an improper position or its transmission power is set too high, it should be controlled within a small range but is not properly controlled.

Third, the purchased mobile phone signal jammer does not meet the radio equipment approval standards, the power exceeds the standard, or it is an inferior and substandard product. After identifying the cause, in order to overcome its impact on mobile communication signals, it is actually very simple: first, use standard products produced by regular manufacturers, second, choose the installation location and direction of action, and third, set the appropriate transmit power. , just limit its transmitted signal to a small, airtight range. As long as the above three points are fulfilled, its impact on nearby mobile communication base stations can be minimized.

2. Improper application of mobile phone signal jammers in schools may cause unnecessary harm to the human body.

Theoretical analysis shows that when the mobile phone signal jammer is working, if the setting is improper and the transmission power is too large, in a small conference room, classroom and other closed spaces, the electromagnetic waves will be superimposed in the small space and pass through the walls and walls that are originally separated from the outside. Multiple reflections from the ceiling and the ground will expose people in the room to serious electromagnetic pollution. According to the survey, the college entrance examination and the high school entrance examination are the occasions where mobile phone signal jammers are used the most. In some examination rooms where mobile phone signal jammers are used, some parties (college entrance examination inspectors, candidates and teachers) become irritable and unable to concentrate. Some candidates There may even be headache symptoms. There are various indications that if the transmission power of the mobile phone signal jammer is turned on too high, it will seriously affect the normal thinking of the candidates in the examination room.

As we all know, radio waves propagate freely in the air. While a mobile phone signal jammer can block the mobile communication base station signal in a specific area and achieve its limited purpose, it will also harm human health to varying degrees. Therefore, mobile phone signals should be used with caution. jammer.
