When it comes to preventing information leakage, signal jammers and mobile phone signal blocking cabinets are two options that can be considered. These two devices are usually used in different occasions and have different purposes.
One of the most well-known applications of mobile phone signal jammers is the examination room. In important examinations such as the college entrance examination, postgraduate entrance examination, and national examinations, in order to maintain order and prevent cheating, the government requires the use of signal blocking equipment, and usually the examination room will be equipped with signal jammers.
In addition to the examination room, signal jammers are also often used in conference rooms, especially in places with high confidentiality requirements such as government agencies and scientific research institutions. In this case, whether to use a cell phone signal jammer or a mobile phone signal blocking cabinet depends on the specific needs of the venue for signal blocking.
For large venues that require signal blocking, multiple mobile phone signal jammers are usually used, and the specific number depends on the size of the area. In this case, it is recommended to use a mobile phone signal blocking cabinet. These cabinets generally have 20-60 compartments, each with a small drawer that can be locked separately with a separate key. Participants only need to put their mobile phones in the drawer at the entrance of the venue before the meeting, and open the cabinet to retrieve their mobile phones after the meeting.
The interior of the mobile phone signal shielding cabinet is electroplated, the surface is electrostatically sprayed, the radiation resistance is strong, the shielding effect is obvious, it can effectively shield the wireless signal, and multiple mobile phones can be stored at the same time. Each drawer is equipped with a secure mailbox lock and can be managed independently.
Compared with the mobile phone signal blocker, the main advantage of the shielding cabinet is that the shielding effect is better, and the signal can be effectively shielded even close to the base station. But the inconvenience of using the cabinet is also a disadvantage. All participants must put their mobile phones in the cabinet, which may be considered a hassle.
Mobile phone signal blockers and shielding cabinets have their own advantages and disadvantages. Therefore, the choice should be made according to the specific requirements of the current situation.
