Jammers are the most effective method for fraud

During the school exam, I heard cases of cheating on mobile phones. It has attracted a lot of attention. Need to submit policy. In order to prevent exam fraud, we will install a phone blocker at the school’s exam site. Prevent cell phone communication. Stop the service of the student’s mobile phone. No complicated operations. Gps interference can maintain the fairness of the test. The purpose is to verify the effectiveness of anti-fraud measures and their impact outside the classroom, which directly interferes with mobile phone communications.

I think this will interrupt the class and reduce the concentration of all students. The students ignored the teacher’s speech. Many teachers try to stop sending messages during class. It has no effect at all. Therefore, please use equipment that can interfere with telephone signals. Considering the result of this situation, a deterrent device was used. This product has a function to block calls. There is an exercise to help students concentrate.
You must obtain a license. It is necessary to meet certain requirements.

GPS radio blocker protects your privacy from GPS tracking applications. Essential equipment for drivers. I want to use it so as not to disturb other parties. It will not affect the normal use of mobile phones and other electronic devices during working hours. You need to buy a portable gps jammer. Its small size and light weight can be moved to a very convenient location. Find all kinds of devices that are out of range. It should be emphasized that many mobile phone jammers will block 3G, GSM, CDMA and DC signals.
