Among the people who use cell phone jammer, some are to avoid exam fraud, and some are to quiet the meeting or confidential information in the meeting. These are all for good wishes and purposes. But it is also for self-interest. For example, the owner of a public phone may use jammers to interfere with the mobile communication base stations around his business location, so that people who work around the public phone they operate, mobile phones are not easy to use. Instead, use public telephones to make calls and increase their economic benefits. In addition, mobile communication operators may also use shielding devices to harm the interests of others, so that they can gain superiority in certain local competitions in the same industry. In addition, the signal jammer is also very easy to add software to become a veritable monitoring device.
The above list is the purpose of people using the device, but no matter what the purpose is, it should not be obtained at the expense of mass mobile communications. In fact, according to research, it is possible to install the device without affecting the normal application of mass mobile communications.
Theoretical analysis shows that when the mobile phone signal jammer is working, if the setting is unreasonable, the transmission power is too large. In a small confined space such as meeting rooms and classrooms, electromagnetic waves accumulate in a small space and pass through the wall originally separated from the outside. Several reflections from the ceiling and the ground will cause the people in the room to be exposed to serious electromagnetic pollution. According to the survey, the college entrance examination and the middle school entrance examination are the places where the signal blocker is the most used, and in some examination rooms where the device is used, some of the parties (the college entrance examination inspectors, candidates and teachers) suffer from irritability and inability to concentrate. Some examinees are even Headache symptoms occur. Many signs indicate that if the transmission power of the device is turned on too large, it will seriously endanger the normal thinking of candidates in the examination room.
Everyone knows that the characteristics of the free propagation of radio waves in mid-air, mobile phone signal jammers can block mobile communication base station signals in a certain area and achieve their limited purpose, but will also damage the health to varying degrees. Use this equipment with caution.
Functional management departments should increase management and control efforts and standardize the application: In response to the increasing use of mobile phone signal jammers from all walks of life, functional departments such as the Radio Management and Security Bureau must increase management and control efforts to standardize the application of this equipment.
