Why does our school install a signal jammer?

There are different opinions. In order to clarify the truth of the matter, the staff of the Student Union's Rights and Interests Department, the Information Center and the Rights and Interests Service Department of the Graduate Union visited the first time, and now I bring you the results of the visit:

1. The real reason for installing the "multifunctional wireless signal jammer" on the Wushan campus of South China University of Technology (33, 34, Bo Xue Building):
In response to higher-level requirements, the School Education Technology Center has established a standardized test center for the national education examination. At present, it is only in the stage of equipment installation and commissioning, and it will be shut down immediately after commissioning. The shielding device will only be used for large-scale exams such as English Band 4 and 6 and graduate entrance exams.

2. The installation and debugging of the equipment of this project caused inconvenience and misunderstanding to the study and life of teachers and students. The Education Technology Center of the school expresses its apologies.

The solution to this is:

Immediately stop all installation and debugging construction.
The construction time is adjusted to after 12 o'clock in the evening: wait until the teaching building is cleared or there are no students in the classroom for self-study before construction. Turn off the shield when the construction is completed.

Specific schedule of construction time:

The Bo Xue Building will be commissioned after 12 o'clock in the evening on October 25;

Buildings 33 and 34 will be constructed and debugged after 12 o'clock in the evening on October 26 and 27 respectively;

3. The signal will not be affected after the signal jammer is turned off;

Quan Xiaoyi couldn't help but breathe a sigh of relief: It turns out that the installation of signal jammers is not to shield everyone's usual signals~
