Most customers have many questions about wifi jammers when purchasing them, such as: Are jammers harmful to the human body? Will the signal jammer become hot after being used for a period of time and damage the machine? Everyone's understanding of mobile phone signal blockers is generally limited to knowing that they can interfere with mobile phone signals. Using it in exams can prevent candidates from using their phones to cheat. During meetings, it can purify the venue environment and avoid being disturbed by sudden phone calls. Interrupting the pace of the meeting can even lead to leaks. Therefore, the use of mobile phone blockers in exam rooms, meeting room blockers, and other places has become more necessary, but some practical issues have not yet been well understood.
Ordinary cell phone jammer do not pose a threat to human health. Firstly, radiation is generally divided into two types. One type is high-energy ionizing radiation, such as hospital X-ray machines or nuclear radiation. The harm is relatively high, but it is relatively rare to come into contact with in daily life; The other type is non ionizing radiation. The most common electromagnetic radiation generated by general electrical appliances in daily life is non ionizing radiation. For example, the radiation generated by people's daily use of microwaves, refrigerators, mobile phones, and computers is electromagnetic radiation. The interference device emits a type of electromagnetic radiation, with relatively low energy. Therefore, it can be determined that general mobile phone shielding devices will not pose a threat to human health. When choosing a mobile phone blocker, it is recommended to choose a qualified and legitimate manufacturer. For example, the signal interference equipment produced by Nanjing Bokang Electromechanical Technology Co., Ltd. has been tested by national authoritative institutions and meets national standards. It will not cause harm to the human body. You can rest assured. use.
Why does the phone still display a signal when the blocker is turned on?
Some customers often encounter this situation when using signal shields again. After the signal blocker is powered on and enters the working state, the phone can no longer communicate, but the signal bar is still displayed on the phone screen. This is because although there is a connection between the phone and the base station, the phone can receive signals from the base station, but this signal is not sufficient to ensure that the phone can communicate and access the internet normally. The number of signal bars displayed on the phone is not accurate. When you try to make a phone call or use data traffic to access the internet, you will find that your phone has no signal, and the number of signal bars on your phone will also disappear.
It is normal for the shell of the mobile phone shield to heat up after being powered on for a period of time. At present, all electronic products generate more or less heat after being powered on for a period of time. Heat continues to accumulate and the surface of the equipment will heat up. As long as the temperature does not exceed the tolerance value of the device, it will not cause damage to the device itself and the device can continue to operate normally. Furthermore, most mobile phone signal blockers have cooling fans to dissipate heat, ensuring long-term stable operation, reducing failure rates, and increasing service life. The electromagnetic signal emitted by the signal shield will only block the corresponding mobile communication frequency band within the internationally specified mobile phone operating frequency band. As long as the working frequency of these devices is consistent with the phone signal, the blocking device has a different frequency band and generally does not affect other devices.
