When paying attention to the update of mobile cell phone jammer, choosing a mobile phone jammer is a prudent question. The mobile phone signal jammer is a device specially designed for entering the examination room. It adopts 7-channel design. Completely solve the transmission problem. The problem of shielding bad signals. We have fundamentally solved the phenomenon of signal instability. With this product, you don’t have to worry about the negative impact of mobile phone signals on local residents. Use built-in antenna. You can also freely arrange the cut-off area for the mobile phone jammer.
In response to feedback from netizens, the reporter recently interviewed President Chen of Shishi No. 3 Middle School. Principal Chen confirmed the issue of “installing mobile phone jammers in the classroom”. According to him, the school currently has more than 2,000 students in more than 40 classes. As the phenomenon of students playing with mobile phones in classrooms is more serious, which has a great impact on normal teaching activities, it is decided to install mobile phone signal jammers in each classroom. Currently, most high school classes have been installed. After these “jammers” are activated, the cell phone signals in the classroom will be blocked. But as soon as you walk out of the classroom, the cell phone signal will be restored.
Regarding the issue of “influencing health,” Principal Chen, who graduated from physics, explained that he has no scientific knowledge. On the one hand, the installed mobile phone jammer is a qualified product, and its electromagnetic radiation meets the relevant national standards, and many schools and examination rooms are already using it. On the other hand, from a physical point of view, the frequency of electromagnetic waves emitted by mobile phone signal jammers is low and will not affect the human body at all.
