Does the signal shielding device in the examination room have the function of blacklist identification?
Nowadays, it has long been common to install signal shielding devices in the examination room during various examinations. Once a student taking the test enters the test, even if the student secretly brings a mobile phone or other electronic communication products in, it will be because of the existence of the signal shielding device in the test room. the communication signals of these mobile phones or electronic communication products will be blocked, so that they cannot be used normally. This is the simplest and most effective solution to prevent students from cheating in exams through electronic products. However, now some customers will consult us, expecting to install more powerful anti-cheating products in the examination room, or hope that the new anti-cheating product has the function of blacklist and whitelist, and can identify the scene during the examination. Which mobile phone users and specific mobile phone numbers are there. Then the question arises: Does the signal shielding device in the examination room have the blacklist recognition function?
First of all, it needs to be clearly known that the signal jamming device in the examination room itself definitely does not have the identification function of blacklist and whitelist. For devices with these functions, the correct name should be called: mobile phone signal management and control system. This type of product is fundamentally different from the basic working principle and working method of the signal shielding instrument in the examination room. In addition, the control system of the mobile phone signal management system is more inclined to the function of the pseudo base station of the mobile phone.
Then, should the signal jammer in the examination room also be made with the function of blacklist and whitelist? Does the examination room in the school really need to identify the numbers of all mobile phone users within the examination room range during the examination? In fact, as long as we carefully analyze the actual examination process, we can know that these functions are not very effective in preventing cheating in the examination.
To prevent cheating during the exam, use the signal shielding device in the exam room to directly block the normal communication of the mobile phone signal, which can simply and directly cut off the communication link of the mobile phone. And if you switch to a mobile phone signal control system, although it has the functions of identifying mobile phone numbers and setting a blacklist, this adds extra workload to the preparation and guarantee of the exam. For example, it is necessary to calculate in advance which mobile phone users should Whitelisted? Which mobile phone users should be set as blacklist? The coverage of the mobile phone signal management and control system needs to be strictly controlled. How can the coverage be accurately controlled? Once the mobile phone users of ordinary people around the school are absorbed, they will be set as blacklist users by mistake, which will have unnecessary impact on external users.
Therefore, the test room signal jammer is convenient and fast to use, and it will not have as many concerns as the mobile phone signal management system.
