Why should 5G mobile phone signal jammers be used carefully?
5G cell phone signal jammers are like an invisible wall that divides society. If not regulated, it is easy to form information islands in cities. For its installation and use, the principle of smaller quantities should be followed. The jammer manufacturer's school is well-intentioned, and the purpose of shielding mobile phone signals is to allow students to study, rest, and stop playing games with peace of mind. Now, mobile phones and games are almost a serious challenge in education. Some time ago, a middle school teacher in Hangzhou wrote an article criticizing a recent popular mobile game, saying that the game has gradually turned mobile phones into "black Internet cafes". His students also said bitterly, "Teacher, I can't control myself." In order to pull the students out of the quagmire, it is necessary to adopt some unconventional management measures such as banning the use of mobile phones and games. The school needs to make a difference in this matter. Blocking mobile phone signals to draw salaries from the bottom is definitely more effective than calling for teachers, making rounds of wards, and formulating strict management measures.
Students' addiction to mobile phones is a headache for parents and schools alike. A school in Fuyang came up with a "new solution": install a mobile phone signal blocking device on the campus and turn it on regularly every night to prevent students from playing with mobile phones at night. However, in the past two days, there have been voices on the Internet. Some residents said that when they use their mobile phones at home, the signal is not stable, and it is suspected that it is related to the school's mobile phone signal blocker.
However, to have good intentions, you have to use the right method. The working principle of the mobile phone signal jammer is very simple. It uses the frequency sent out to affect the frequency of the mobile phone signal. To put it bluntly, it is like "loudness over whispering" when speaking. The management department also said: "The shielding device belongs to a kind of radio station. Except for the radio stations with small influence such as mobile phone communication terminals and home WIFI transmitters, which do not need approval, all other radio stations are related to the use of frequencies. It needs to be approved." It can be seen that the problems involved here are not simple, it is not that it can be installed by pretending, and it is not possible for anyone to pretend.
