Question: When the mobile phone signal jammer is working, why do some mobile phones still have signal indicators?

A: This is just an illusion. In fact, at this time the mobile phone has been unable to communicate. When you press the pull button at will, you will find that there is no signal indication on the phone.

Q: Will the cell phone jammer interfere with the normal operation of other electronic devices?

Answer: No. This is because the electromagnetic signal emitted by the mobile phone signal jammer falls completely within the mobile phone working frequency band stipulated by the state, which will only block the mobile phone communication. And this signal is always in a relatively static state and will not affect any electronic equipment.

Q: Is the mobile phone security signal jammer harmful to human body and mobile phone?

Answer: Please rest assured that the electromagnetic signal strength emitted by the mobile phone safety signal jammer is very weak, and the test data shows that this signal strength is far from causing harm to the human body. At the same time, the mobile phone signal jammer only blocks the forward signal of the mobile phone, so that the mobile phone cannot contact the base station, so it will not cause any damage to the mobile phone itself.

It is a real environmental protection product. It is an information security product developed for the internal use of the national security department. The security bureau has very high requirements on the environmental performance of the product. Our company's products have overcome a series of technical problems, reducing the transmission power to the greatest extent, ensuring that the electromagnetic radiation is far below the national standard (12 microvolts per square meter), and the shielding of a single shielding device With a radius of more than 20m, it is a safe product that is truly harmless to the human body and environmentally friendly (only 8 microvolts per square meter). Other products in the same industry, in order to expand the shielding radius of the shielding device, simply increase the transmission power, which also increases the electromagnetic radiation intensity accordingly (up to 40 microvolts per square meter, the radiation is more serious than the microwave oven -300W), It is bound to endanger human health. Some products claim that the shielding radius reaches 30-50m, but their actual transmission power seriously exceeds the standard, seriously endangering human health. Our company's mobile phone signal jammer uses the most advanced high-frequency signal program control technology at present. After careful development, the smart jammer has a transmission power of no more than 1W. When the base station signal field strength is less than 35dBuv, the effective shielding radius can reach 50m. , It can reach 100m in open places. For large places, installing several units at different angles can solve the problem, and it can ensure that there is no harm to people.

Q: Is there a difference in the working distance of the mobile phone signal jammer when used indoors and outdoors?

Answer: Yes. The effective distance (30-40 meters) of the mobile phone signal jammer generally refers to the indoor distance. In outdoor open areas, the effective distance of shielding can reach hundreds of meters. It should be pointed out that whether it is used indoors or outdoors, the effective distance of the jammer has a certain relationship with the environmental conditions at that time, such as the distance from the base station and the location of the installation. Therefore, when using a mobile phone signal jammer, this factor should be fully considered to avoid shielding dead angles that affect the shielding effect.

Q: Does the mobile phone signal jammer have the same effect on GSM mobile phones and CDMA mobile phones?

Answer: Since the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the effective shielding distance of CDMA mobile phone signal jammers for CDMA mobile phones is smaller than that of GSM mobile phones, but the difference is not very big, about 2-4 meters. However, users are also reminded that in some particularly important places, the number of mobile phone safety signal jammers in the field should be increased if necessary to ensure the shielding effect on CDMA mobile phones.

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

Answer: This is a normal phenomenon. In terms of design, we use the thermal conductivity of the aluminum alloy brushed case to assist in heat dissipation. So as to ensure long-term stable work. Therefore, the machine case will not be damaged if it gets hot.

Question: Is the product of the mobile phone signal jammer qualified, and does it comply with the relevant national regulations? Is there any related testing?

Answer: The mobile phone signal jammer is an information security product with complete independent knowledge sovereignty developed by using modern high-tech, through in-depth analysis of communication mechanism, and comprehensive comparison of electromagnetic emission suppression methods. It can form an electromagnetic protection field around its installation site, which can effectively prevent mobile phones from leaking secrets and eliminate noise pollution generated by mobile phones. The mobile phone signal jammer will provide you with a safe and quiet space and become your reliable and loyal guard!
