Slight sparks will be generated when the cell phone battery starts

  With the increasing technological trend of cheating methods, the norms of examination room discipline will also take corresponding countermeasures, which is the reason why many examination rooms have begun to adopt , but for examiners, it is still necessary to block the signal for the examination. The office should formulate specific countermeasures. After all, many people's test scores will directly determine the fate of the workplace, so it is particularly important to strengthen the technology of anti-shielding equipment. This is also a technical condition that cannot be ignored to improve test scores. After all, today's signal shielding And anti-shielding has been achieved at the theoretical level. It is undeniable that the mobile phone signal jammer equipment in the examination room can not only meet the basic signal shielding needs, but also has an ideal effect on the signal shielding around the examination room because of the use of high-power equipment. The specific problem of how to shield the signal in the exam shows that the anti-shielding technical equipment still needs to be used as a solution to effectively relieve the signal interference under the same conditions. I believe this is also of great help to meet different signal reception needs. The key is to guarantee the transmission quality.

  When the cell phone battery starts up, when the ringer rings, it can generate enough energy to cause a slight spark that can cause a fire. Relevant departments such as petroleum, chemical industry, and security have expressly stipulated that the use of mobile phones in gas stations is prohibited. The equipment of the gas station is controlled by the computer. The mobile phone signal will affect the normal operation of the equipment, which will lead to inaccurate measurement. More importantly, the mobile phone will spark during the dialing process, which can easily cause fire and cause the gas station to explode. The current mobile phone signal is almost everywhere, and all electrical equipment is surrounded by it. When the mobile phone is not in use, the interference of the surrounded signal to other electrical equipment is minimal. This is because there is no data exchange between the mobile phone and the base station when the mobile phone is not in use, and it is impossible to form a mutation signal. There is a relatively stable electromagnetic field around the device, that is, a static electromagnetic field. The interference of this static electromagnetic field to the electrical equipment is almost zero.

  In some areas that require strict control, such as national defense areas, prison cells, detention centers, etc, the level of information confidentiality is very high, and strict supervision of mobile phones should be carried out. In the areas of national defense, prisons, detention centers, etc., blocking mobile phone signals can greatly prevent the possibility of leaks. In addition to the applicable occasions of the three types of mobile phone signal GPS jammers described above, other areas such as gas stations, petrochemical plants, hospital outpatient clinics and other areas where phone calls are strictly prohibited, install , and the effect is also very satisfactory. When the jammer is used, it can be selected according to the applicable situation. If the place is relatively large, the mobile phone signal jammer with excessive output power can be used. The excellent signal jammer can carry out high-efficiency networking solutions and fulfill the requirements of mobile phone signal shielding in higher areas.

  Judging from the size of the examination room, it is not very big, and it can be conveniently placed anywhere in the examination room without having to bother to find a special place to place it. In addition, the mobile phone signal shielding device in the examination room operates with almost no noise, and will not interfere with the examination room environment due to the use of the examination room signal shielding device, nor will it affect the state of the candidates. In addition, it is mainly used to interfere with mobile phone signals, so there is no need to worry about the impact of the mobile phone signal shielding device on the normal operation of other electronic equipment in the test room. At the same time, the mobile phone shielding device in the examination room only interrupts the connection between the mobile phone and the base station, and the electromagnetic radiation generated is far lower than the national standard, so there is no need to worry about affecting people's health.
