Can mobile jammers really build a style of study?

Aguirre Henry Dec 24, 2020 10:30

Signal jammers are installed in the classrooms, and the teacher only needs to press a button, and the mobile phones become bricks. The teacher's control of this high-tech will undoubtedly make the students "frightened."

On the 27th, Liu Shuai, a student from China University of Petroleum (East China), uploaded a photo in his Renren.com album. This photo was taken of a multimedia teaching console in a school classroom. At first glance, it looks no different from the multimedia teaching equipment on the podium of other colleges and universities, but as long as you look closely, you will find the bright spot: there are two buttons on the console that say the phone cell phone jammer is on and off.

Liu Shuai also attached a caption to this picture. The caption mentioned that "as long as the teacher is willing, when the teacher presses the button during class, the cell phone of the whole class will have no signal." And expressed his own opinion, thinking that if you want to maintain your so-called good school spirit in this way, "then it is really not far from failure."

Netizen: What if there is an emergency call or communication?

Most netizens feel that this approach of China University of Petroleum (East China) is “slightly brutal”. In the survey conducted by Renren.com on "Should mobile phone signal be blocked in class?", the number of netizens who did not support was more than twice the number of supporters.

Some netizens think that this kind of "high school-oriented" education management method is not what the university would choose in their minds. There are also netizens who think that shielding mobile phones is of little significance, "you can play stand-alone games, read novels, and sleep." Netizens are most worried about the phone's lack of signal and emergency calls or communications.

However, some alumni felt that Liu Shuai misinterpreted the intention of the school and the network center, "According to my analysis, this is not for class, even the teacher will not open it, because the teacher's mobile phone has no signal, this should be convenient for exams." . Liu Shuai replied to the alumni: But now some teachers have begun to use it wisely.

Build style of study? Block cell phone signals in university classrooms

The teacher clarified that it is only used in exams

In the East China Bar of China University of Petroleum, it was discovered in the East China Bar of the China University of Petroleum that some students who stayed in school during the summer vacation of 2013 witnessed the school installing a cell phone signal jammer in the classroom and posted photos.

On August 19, Mr. Chen, the director of the Shida Network Center, clarified that the so-called signal jammers and cameras are built in conjunction with standardized examination rooms. They are only used during examinations. They are not used to shield mobile phone signals during normal times. They were installed in the classroom last year. Supplement to surveillance cameras, the standardized examination room is constructed in accordance with the requirements of the relevant documents of the Ministry of Education and the Education Department. In addition, the wireless network established by the lecture hall group and Nanjiao is a wireless network based on campus network account (UPC-Stu), which has nothing to do with mobile wireless (CMCC).

Some universities have installed signal jammers

This is not the one who installed signal mobile phone jammers in the classroom. China University of Petroleum (Beijing) used mobile phone signal jammers throughout the day in its third teaching building in February 2012. It is stipulated that the class starts from 8 am to 11 noon. From 1:45 to 5:15 in the afternoon, and from 6:30 to 9:10 in the evening, a total of nearly ten hours is the turn-on time of the mobile phone signal shielding device. For this reason, some students reported this situation to the Beijing Municipal Education Commission.

In addition, in May 2007, a mobile phone signal shielding device was installed on the third floor of the Fuchengmen campus of Beijing Technology and Business University. In the building, all mobile phone signals were blocked. The school claimed that this was to build a style of study and prevent students from receiving and calling mobile phones during class. However, this practice was questioned by some teachers and students. In May 2006, the Central University of Finance and Economics issued an announcement on its website stating that the school's teaching building and the lecture hall of the attached building would install cell phone signal shielding devices. Students were arguing about this. Many media in Beijing published reports on this, which caused widespread controversy in society.
