In important exams such as the college entrance examination, the high school entrance examination, and the College English Test Band 4 and 6, mobile phone signal jammers are deployed in the examination room to maintain the fairness of the examination, ensure the stability of the examination environment, and prevent candidates from cheating. However, there are still some people who, out of personal desire, try to bypass the existing protective measures and carry out extreme damage. So, how can the Cell Phone Jammer in the examination room prevent deliberate damage?
Usually, there are two ways for examination institutions to use mobile phone signal jammers in the examination room. The first is to use desktop signal jammers, which are distributed to invigilators or distributed to various examination rooms before the examination and collected after the examination. However, this method also has some challenges. The process of issuing and recovering signal jammers is time-consuming and labor-intensive, and the installation and use are also relatively casual. Some invigilators will directly place signal jammers on the podium, stools, and floor. Since the jammer requires power and needs to be connected to the AC power socket through a power cord, this method lacks standardization, and frequent issuance and collection of jammers can easily cause equipment damage.
The second way is to use a wall-mounted mobile phone jammer in the examination room, that is, the jammer is pre-installed in the examination room and only needs to be started at the beginning of the examination. This installation method is more standardized and safer. Since the equipment is installed slightly higher than the top edge of the blackboard, it can more effectively prevent vandalism.
Analyzing the methods of deliberately destroying mobile phone jammers in the examination room, the most common means include unplugging the jammer’s antenna, power cord, or network cable used for communication. In order to effectively combat these destructive methods, mobile phone jammers used in modern examination rooms usually use built-in antennas, and the equipment is encapsulated in the shell, and the antenna cannot be directly contacted from the outside. For example, our JAMMERSIGNAL Electromechanical Technology Co., Ltd. has developed the SMa-818B5 mobile phone signal jammer specifically for the examination room environment. It uses a hidden installation box to centrally place switches, power cords, and network communication cables, further strengthening the protection against human damage.
