Gao Shengyong, director of the Propaganda Department of Hohhot Vocational College, said that at the moment when students complete their studies or final exams, the school adopts a system of inspections by school leaders and invigilators, and no mobile phone jammers are used for internal exams. According to Gao Shengyong, the exams using Cell Phone Detector And Jammer Mini Project are all national exams. 3 to 4 national exams every year need to occupy the school's premises.

Gao Shengyong said that the test period may have an impact on the mobile phone signals of surrounding residents, but it is impossible to affect it every week. At present, the school's English Band 4 and 6 exams are conducted in the University City of the East Campus. There are no large-scale exams recently. cell phone jammer
Hu Bisi Haratu, deputy director of the Academic Affairs Office of Hohhot University for Nationalities, said that Cell Phone Detector And Jammer Mini Project is not used in the examinations of the school, and the main purpose is to invigorate the examinations by teachers. Every year, the national examinations use mobile phone jammers. But before the jammer is used, the electromagnetic frequency has been adjusted, and the mobile phone will naturally have a signal if it goes out of the test range. During the exam, the shielding area is limited to classrooms and corridors, and residential buildings are unlikely to be affected. Hubishalatu said that there have been cases of no signal or weak signal in the office building, and the staff could not explain why the residents of the Mongolian expert's building had no signal when they were at home.
