Have you remembered all these common problems of mobile phone signal jammers?

　　When we are using the Shenzhen mobile phone signal jammer, we will inevitably encounter some problems, so what are the common problems? Let’s understand together:

　　(1) When the mobile phone signal jammer is working, why some mobile phone signal indicators show that there is still signal?

　　Answer: This is just an illusion. In fact, the mobile phone can no longer communicate at this time. When you press the pull button at will, you will find that there is no signal indication on the signal indicator.

　　(2) Will the mobile phone signal 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 is completely within the working frequency band of the mobile phone specified by the country, which will only block mobile communications. And this signal is always in a relatively static state and will not affect any electronic equipment.

　　(3) Is cell phone signal jammer harmful to human body and cell phone?

　　Answer: Please rest assured that the strength of the electromagnetic signal emitted by the mobile phone signal jammer is very weak. The test data shows that this signal strength is far from harmful 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 communicate with the base station, so it will not cause any damage to the mobile phone itself.

　　(4) Is there a difference in the effective shielding distance of the mobile phone signal jammer when used indoors and outdoors?

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

　　(5) Does the mobile phone signal jammer have the same shielding effect on GSM mobile phones and CDMA mobile phones?

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

　　(6) After the mobile phone signal jammer works for a period of time, the case becomes hot. Will it damage the machine if it works for a long time?

　　Answer: Thank you for your carefulness. This is a normal phenomenon. In design, we use the thermal conductivity of the fan and the wavy thick aluminum alloy thermal strip to assist in heat dissipation. So as to ensure stable work for a long time. Therefore, the hot casing will not damage the machine.

　　(Can the antenna of the mobile phone signal jammer with antenna be locked at will? Can the mobile phone signal jammer be placed casually?

　　Answer: The antenna must be installed according to the corresponding identification of each channel on the host before turning on the power of the host. The effective coverage of the shield is a circular area centered on the shield. Therefore, when using the shield, pay attention to the correct placement of the shield to avoid blind corners of the shield.

　　Have you remembered all these functions of the mobile phone signal jammer?

　　In many places at present, devices such as mobile phone signal jammers are used. Do you know what the function of mobile phone signal jammers is? Let’s understand together:

　　Phone signal blocker is mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military places and other places where the use of mobile phones is prohibited. It is understood that cell phone signal blockers on the market can limit cell phone signals to 500 meters away from the launching station. The shielding radius is adjustable, and the coverage area can reach more than 30 square meters. The mobile phone signal shielding device can only shield the mobile phone signal and does not affect other electronic equipment. Save energy, the power is 12W-480W. During operation, the shield scans from the low end of the forward channel to the high end at a certain speed. The scanning speed will cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, causing the mobile phone to fail to establish a connection with the base station. Mobile phones appear to search the network, no signal, no service system, etc.
