The cell phone signal jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, mobile phone no signal, no service system, etc.

Nowadays, smart phones have long been a must-have for personal life, and there are not a few people in the student party who have mobile phones. How to control the use of mobile phones by students, how to establish the balance between learning and entertainment... It seems that it has always been a problem that lies in front of parents and schools.

The Silver Lake Experimental School in Fuyang District, Hangzhou used a "new solution": a cell phone signal shielding device was installed on the campus and turned on regularly every night to prevent students from playing mobile phones at night. However, in the past two days, there have been voices on the Internet that some residents living in Shijiayuan Garden in Fuyang said that when they use their mobile phones at home, the signal is not stable, and it is suspected to be related to the school's mobile phone signal shielding device.

The reporter from Qian Bao contacted Teacher Zhao, director of the Audio-visual Education Center of Hangzhou Yinhu Experimental Middle School. Teacher Zhao said that the school’s mobile phone signal shielding device has been installed for a period of time, mainly to prevent school students from playing with mobile phones at night.The shielding instrument is activated between 10 o'clock in the evening and 4 o'clock in the morning of the next day, and is currently in normal use.

As for the installation of mobile phone signal shielding device, do I need to file with the local radio management department? Teacher Zhao said that the school was not responsible for the installation of this set of equipment, so the specific process is not clear. It is recommended that the reporter consult the local radio management department.

In addition, the reporter also asked Teacher Zhao whether the cell phone signal jammer devicewould affect the lives of surrounding residents? Teacher Zhao said that so far, there has been no reports from nearby residents about interference outside the school.
