Schools and prisons use mobile phone signal jammers to be safety-oriented

Schools and prisons should follow these three principles when using cell phone jammers

Radio management

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

Among those who use cell phone jammer, some are to prevent cheating in exams, and some are for quietness of the meeting or confidentiality of meeting information. These are all for good wishes and purposes. But there are also for their own benefit. For example, the owner of a public phone may use a jammer to interfere with the mobile communication base station near his business location, so that people working near the public phone operated by him can use the mobile phone instead of working Public telephone calls increase their economic income. In addition, mobile communication operators may also use shielding devices to harm each other’s interests, so that they can gain advantages in certain local competitions in the same industry. In addition, the mobile phone signal jammer is also easy to add software, becoming a veritable eavesdropping

The above list is the purpose of people using mobile phone signal jammers, but no matter what the purpose is, they should not be exchanged at the expense of public mobile communications. In fact, according to research, it is possible to install mobile phone signal jammers without affecting the normal use of public mobile communications. There are three reasons that cause the mobile phone signal jammer to disturb the mobile communication base station signal:

First, users of mobile phone signal jammers did not take into account the communication needs of outsiders at all, and the target was wrong. The mobile phone communication of a small group of people (such as examinees) should be restricted, but the target was expanded to other ordinary people around.

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

Third, the purchased cell phone signal jammer does not meet the approved standards for radio equipment, the power exceeds the standard, or is a low-quality and substandard product. Finding the reason, in order to overcome its impact on mobile communication signals, it is actually very simple: first, use standard products produced by regular manufacturers, secondly, choose the installation location and direction of action, and thirdly set appropriate transmission power. , It is enough to limit the transmitted signal to a small enclosed area. As long as the above three points are achieved, its impact on nearby mobile communication base stations can be minimized.

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

Theoretical analysis shows that when the mobile phone signal jammer is working, if the transmission power is too large due to improper setting, in a small confined space such as meeting rooms and classrooms, electromagnetic waves are superimposed in a small space and pass through the walls that are originally separated from the outside. Multiple reflections from the ceiling and the ground will cause people in the room to be exposed 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 (the college entrance examination inspectors, examinees and teachers) are irritable and unable to concentrate. Individual examinees Even headache symptoms appear. Various signs indicate that if the transmission power of the mobile phone signal jammer is turned on too large, it will seriously affect the normal thinking of candidates in the examination room.

As we all know, the characteristics of the free propagation of radio waves in the air, mobile phone signal jammers can block mobile communication base station signals in a certain area and achieve their limited purposes, but also harm human health to varying degrees. Therefore, you must use mobile phone signals with caution. Shield.

The functional management department should strengthen supervision and regulate the safe use of mobile phone signal jammers in schools and prisons

Faced with the increasing use of mobile phone signal jammers from all walks of life in the society, functional departments such as the Radio Management and Security Bureau must increase supervision and regulate the use of mobile phone signal jammers
