Precautions for using full-screen segment cell phone signal blockers in schools from dojammer's blog

The application of full-screen segment cell phone signal blockers cannot give up the cost of modern communication technology for the people.

Among the people who use full-screen segment cell phone signal blockers, some are to prevent cheating in exams, and some are to keep the venue quiet or exchange privacy protection, which are all derived from the desire and purpose of excellence. However, there are still their own interests. For example, the owner of a telephone booth is likely to use a full-screen segment cell phone signal blocker to affect the mobile communication base station around the business location, making it difficult for people working near the telephone booth to use their mobile phones, but to change to voice chat in the telephone booth to improve their source of life. In addition, mobile communication operators may also use full-screen segment mobile phone signal blockers to harm the interests of the other party, allowing you to gain an advantage in some of the same industry competition.

The above is a lot of people use full-screen segment cell phone signal blockers to say, but no matter what the purpose is, do not give up the cost of modern communication technology for the people. In fact, according to scientific research, it is possible to assemble a full-screen segment cell phone signal blocker without affecting the start of modern communication technology for the people. There are three reasons why the full-screen segment cell phone signal blocker disrupts the mobile communication base station signal:.

First, the user of the full-screen segment cell phone signal blocker did not consider the communication fraud of the smiling face, and the target of action was wrong. It should have restricted the mobile phone communication of a small number of people (such as students), but expanded the overall goal to other general people around.

Second, the operation steps are unscientific. Because the installation method of the full-screen segment cell phone signal blocker is unscientific or its signal strength is set too high, it should be controlled within a reversible range but it is not well controlled.

Third, the purchased full-screen segment cell phone signal blocker does not meet the radio equipment approval standards, the power exceeds the standard, or it is a counterfeit and substandard product. Finding the cause, in order to solve the impact on the mobile subway signal, it is actually very simple: first use reliable manufacturers to meet the standards, secondly select the assembly position and direction of action, and thirdly set the appropriate signal strength to limit the transmission signal to a closed reversible range. If the above three points can be achieved, the impact on nearby mobile communication base stations can be minimized.

2. The unscientific application of full-band cell phone signal blockers in schools may cause unnecessary harm to the human body.

Basic knowledge analysis shows that when the full-band cell phone signal blocker is working, if the setting is not standardized and the signal strength is too high, in a reversible large conference room, classroom and other enclosed spaces, electromagnetic waves accumulate in a small space, and according to the original external distance wall, ceiling, and ground multiple reflections, the staff in the room will be in a relatively serious electromagnetic wave radiation. According to the survey, the college entrance examination and the high school entrance examination are the venues where the full-band cell phone signal blocker is used the most. Therefore, some test sites using the full-band signal blocker have caused some victims (college entrance examination inspectors, teachers and students) to become restless, unable to concentrate time and energy, and some students even have headaches. All signs indicate that if the signal strength of the full-bandcell phone signal blocker is too high, it will affect the normal thinking of the candidates who register in the examination room.

As we all know, radio waves are easily transmitted in the air. While the full-screen segment signal blocker is used to isolate the base station signal in a certain area and achieve its limited purpose, it also affects health to varying degrees. Therefore, the full-screen segment signal blocker must be used with caution.
