In the information age, with the rapid development of communication technology, mobile phones have become an indispensable tool in people's daily life and work. However, the widespread use of mobile phones has also brought us some more or less influence, especially as a channel for leaking information, which poses a threat to the security of confidential information. Therefore, as long as you carry a mobile phone in confidential occasions, whether in use or in standby mode, there is a possibility of information disclosure and a great security risk to the school examination. What are the main considerations for the school examination room in selecting mobile jammers?

First of all, we should consider the location used by the school. For example, in the classroom, we can usually install it on the corridor or on the back wall of the classroom. Then the mobile jammer can be turned on at any time during use, and it can cover the whole classroom. Generally, the built-in mobile jammer is used in the school examination room.

Secondly, with the popularity of 5G networks, if we choose mobile jammers from the functional point of view, and if the budget is sufficient, we can consider new 5G mobile jammers. The 5G mobile jammers we said already include 2G, 3G, 4G and 5G mobile jammers of China Mobile Unicom's three networks.

Finally, when choosing the mobile jammer, we first choose a regular channel product with a brand, and the machine package includes instructions, warranty cards and other information. If you buy a "three no" product, you can't guarantee the after-sales service in the later period.

This is how the school examination room chooses to purchase a wireless signal shielding instrument. It should consider all aspects comprehensively and choose a regular company product with a registered brand.
