Is the jammer radiation problem really as serious as it says?

To prevent students from using cell phones, schools often use jammers to deceive. For security and management considerations, prisons can also use mini jammers to prevent prisoners from communicating with the outside world and increase the threat to the prison. If used properly, mobile jammers are a relative advantage. Those who are constantly on the phone may be able to remain silent, regardless of the circumstances. Interference transmits a high-power signal on the opposite frequency to the cell phone, causing the two signals to collide and cancel each other out. This is the fundamental mission principle of any jammer. Sophisticated devices block only one set of frequencies. High-end equipment can block all frequencies at once. Cell phones are full-duplex devices, which means they use two different frequencies. One listens, the other speaks. Some basic jammers can only block one of these frequencies. Advanced jammers not only interfere with all cell phone signals, but many others as well. It also has a unique frequency switch that can be selected according to your needs.

More importantly, are smartphones immune to cell phone interference? This is completely unnecessary. Mobile intelligence doesn’t mean only using the frequency band of the signal. Only in terms of hardware and software, the functions of machines are becoming more and more diverse, but the frequency band of the communication network is still in use and the frequency band of the signal is opposite. other cell phones. The answer is yes. If this signal spectrum is not used, the smartphone uses the same signal frequency and does not interfere with the phone. However, such technology does not seem to exist.

In addition, students’ use of cell phones in the classroom disrupts the normal educational system, which is beyond their rights and should be restricted. Cell phone jammers are widely used in schools, but netizens have mixed opinions. Some netizens are concerned about “radiation health”, and some netizens think it is useful to deal with the scene of Mr. using his mobile phone in class. The school said the measure was necessary to prevent the use of cellphones in the classroom and increase barriers to learning. The radiation is much lower than that of mobile phones and does not affect health.
