How can the mobile phone jammer used in the exam prevent vandalism?
Whenever the college entrance examination, high school entrance examination or college English test CET-4 and CET-6, the mobile phone jammer in the examination room, as an important tool to maintain the fairness of the test, ensure the stability of the test room and prevent candidates from cheating, will work throughout the entire test process. However, there are still a small number of people who, out of personal desires, try to avoid the protective measures in the examination room, and even resort to some extreme destructive behaviors. So how can the mobile phone jammer in the examination room prevent man-made sabotage?
Usually, during various types of examinations, the competent unit of the examination will use two methods when using the mobile phone jammer in the examination room. The first is to use a desktop interference device and distribute it to the invigilator before the examination or distribute it to each Examination classrooms will be recycled after the examination is over. This method will bring some problems: the process of issuing and recycling mobile phone jammers in the examination room is time-consuming and laborious, and the installation and use are relatively casual. Some invigilators place the devices directly on the podium, while others place them on On a stool or on the ground, because the interference device must be powered on to use it, and the AC power cord needs to be used to connect the main unit of the device to the power socket, so this method is very irregular. There is also a very important point: in the process of frequently distributing and recycling mobile phone jammers in the examination room, there will inevitably be damage and damage to the equipment.
Another way is to use a wall-mounted mobile phone jammer for the test room, which means that the interference device is installed in the test room in advance, and it only needs to be turned on when the test starts. This installation method is more standardized and safe, and since the installation height will be slightly higher than the upper edge of the blackboard, it is more effective in preventing man-made damage.
From the analysis of the methods of man-made destruction of mobile phone jammers in the examination room, the most common methods of destruction are: unplugging the antenna of the interfering device, unplugging the power cord of the interfering device or the network cable for network communication, etc. At present, in order to effectively prevent these damage methods, the mainstream mobile phone jammers in the examination room basically adopt the method of built-in antenna, that is, the device is made into a whole shell and installed closed, and the antenna can no longer be directly accessed from the outside. And the SMa-818B5 mobile phone jammer specially designed for the examination room environment by our Nanjing Bokang Electromechanical Technology Co., Ltd. has achieved the purpose of concentrating the switches, power lines, network communication lines, etc. of the equipment in a concealed installation box , which makes the level of protection against man-made damage has been further improved!
