Questions to know about mobile phone signal jammers

When most customers buy jammers, they will have a lot of questions about wifi jammer, for example: Is the jammer harmful to the human body? Will it damage the machine if the jammer becomes hot after using it for a period of time? Everyone's understanding of mobile phone signal jammers is probably limited to knowing that it can interfere with mobile phone signals. Using it in exams can prevent candidates from using mobile phones to cheat. During meetings, it can purify the environment of the venue and will not be disrupted by sudden calls. Interrupt the rhythm of the meeting, and even lead to leaks. Therefore, the use of mobile phone jammers in the examination room, conference room jammers, etc. in these places has become more necessary, but some practical problems are still not well understood. Let me answer the doubts that have always been in your mind.

1. Is the mobile phone jammer harmful to the human body?

General mobile phone jammers will not pose a hazard to human health. First of all, radiation is generally divided into two types. One is high-energy ionizing radiation, such as X-ray machines in hospitals or nuclear radiation. The damage is relatively large, but there is relatively little exposure in daily life; the other is non-ionizing radiation. The most common electromagnetic radiation produced by general electrical appliances in daily life is non-ionizing radiation. For example, the radiation generated by microwave ovens, refrigerators, mobile phones and computers that people use every day is electromagnetic radiation. What the interference equipment emits is a kind of electromagnetic radiation, and the energy of the electromagnetic radiation emitted is relatively low, so it can be judged that the general mobile phone jammer will not pose a hazard to human health. When choosing a mobile phone jammer, it is recommended to choose a qualified regular manufacturer. For example, the signal jamming equipment produced by Nanjing Bokang Electromechanical Technology Co., Ltd. has been tested by the national authority and meets the national standards. It does not pose a hazard to the human body. You can rest assured. use.

2. After turning on the shielding device, why does the mobile phone show that there is still a signal?

When some customers use the signal jammer again, they often encounter such a situation. After the signal jammer is powered on and enters the working state, the mobile phone can no longer communicate, but there are still signal bars displayed on the mobile phone screen. This is because, although there is a connection between the mobile phone and the base station, the mobile phone can receive the signal of the base station, but this signal is not enough to ensure that the mobile phone can communicate normally and surf the Internet. The number of signal bars displayed on the mobile phone is false. When trying to dial When you make a phone call or use data traffic to surf the Internet, you will find that the mobile phone has no signal, and the number of signal bars on the mobile phone will also disappear.

3. After working for a period of time, the casing of the mobile phone jammer becomes hot. Will it damage the machine if it works for a long time?

It is a normal phenomenon that the casing of the mobile phone jammer becomes hot after being powered on for a period of time. At present, all electronic products will generate some heat more or less after being powered on and used for a period of time. The heat continues to accumulate, and the surface of the device will hot. 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 work normally. Furthermore, most of the mobile phone jammers will have a cooling fan to dissipate heat, which is used to ensure the long-term stable operation of the mobile phone signal jammer, reduce the incidence of failure, and increase the service life.

4. Will the mobile phone jammer affect the normal operation of other devices?

The mobile phone jammer generally does not affect the normal operation of other devices. The electromagnetic signal emitted by the signal jammer is within the internationally stipulated mobile phone operating frequency band, and will only block the corresponding mobile phone communication frequency band. As long as the operating frequency of these devices is consistent with the mobile phone signal Jammers have different frequency bands, and generally will not affect other devices.
