In large exams, do they use jammers to block cell phone signals?

Whenever we take a large exam, our cell phone signal is always empty. Has the school installed a mobile phone jammer?

High school will be the most important moment in our lives. Because of this critical period, we can get university admission tickets. We must learn knowledge. At the same time, we must also learn some counter-pressure ideas. This will be of great help to the universities where we are admitted. In addition, if we study wholeheartedly, we will have more practical skills and knowledge. In order to improve grades, the school will organize various types of examinations to create a calm and fair environment during the examination. Therefore, schools need high-power cell phone jammer so that candidates cannot check their mobile phones during the exam and have a fair competition and opportunities to demonstrate their abilities.

The jammer emits a frequency band to block the microphone on the connected speaker
