Case I: Maintain information security in the examination room, an artifact that blocks signals in the entire frequency band!

Examination is a method of equal competition and merit-based admission. To ensure absolute fairness, cheating must be eliminated. In the information age, cheating methods are more high-tech. Only by completely blocking external signals can cheating be eliminated. Therefore, a "weapon" for cheating using electronic products - signal jammers was born.

The project is located in a university in Beijing. There are many examination rooms, and there are often English CET-4 and CET-6 examinations and graduate admissions examinations. Therefore, the school decided to purchase signal jammers to ensure information security in the examination rooms.

The customer compared multiple brands of jammers on the market and finally chose the Linchuang DXK3000K12-channel 5G jammer. This jammer was independently developed by Lin Chuang and is mainly used in school examination rooms, prisons, detention centers and other places. It has been widely recognized since its launch. Lin Chuang took the lead in mastering 5G mobile phone signal shielding technology and established long-term cooperative relationships with multiple schools.

The shielding area is the school ladder classroom, with three classroom areas of 400㎡, 200㎡, and 200㎡. To ensure the shielding effect, it is recommended that each classroom use 2 DXK3000K jammers to effectively shield all 2G/3G/4G/5G Wireless communication signals such as mobile phones, WiFi, and Bluetooth are the security guards of confidential conference venues and standardized examination rooms.
