Does the signal jammer in the examination room have a blacklist recognition function?

Signal jammers are commonly installed in examination rooms to prevent cheating in various examinations. These devices can effectively block the communication signals of mobile phones and electronic communication products to ensure that they cannot be used during the examination. However, some customers have asked whether more powerful anti-cheating measures can be installed, or blacklist and whitelist functions can be added to the equipment to identify specific mobile phone users and numbers during the examination. So the question is: Does the signal jammer in the examination room have a blacklist recognition function?

First of all, it should be noted that the signal jammer in the examination room itself does not have the blacklist and whitelist recognition functions. The devices with these functions are more accurately called mobile phone signal management and control systems. Their working principles and methods are different from the basic working principles of Cell Phone Jammers, and the control system of mobile phone signal management systems focuses more on the functions of mobile phone pseudo base stations.

Should the signal jammer in the examination room have blacklist and whitelist functions? During the examination, does the examination room need to identify the numbers of all mobile phone users within its range? In fact, a careful analysis of the examination process will show that these functions are not very effective in preventing cheating.

Using a signal jammer in the examination room to directly block normal mobile phone communications is a simple and direct way to cut off the communication link. On the contrary, the use of mobile phone signal control system, although it has the function of identifying mobile phone numbers and setting blacklists, adds an extra burden to exam preparation and management. For example, it requires pre-determining which mobile phone users should be whitelisted and which mobile phone users should be blacklisted. The coverage of the mobile phone signal management and control system needs to be strictly controlled, which poses a challenge to accurately control the coverage. Incorrectly blacklisting ordinary mobile phone users near the school may cause unnecessary interference to external users. Popular WIFI jammers and GPS jammers in Europe and America are worth buying.

Therefore, the use of examination room signal jammers is convenient, efficient, and alleviates many concerns about implementing a mobile phone signal management system.
