How is the signal jammer used and is it harmful to the human body?
1. When the signal jammer is working, why some mobile phone signal indications still have signal indications?
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 signal jammer interfere with the normal operation of other electronic devices?
Answer: No. This is because the electromagnetic signals emitted by the signal jammer are completely within the working frequency band of the mobile phone specified by the country, which will only block the communication of the mobile phone. And this signal is always in a relatively static state and will not affect any electronic equipment.
3. Are signal jammers harmful to humans and mobile phones?
Answer: Please rest assured that the strength of the electromagnetic signal emitted by the signal shield is very weak. The test data shows that this signal strength is far from harmful to the human body. At the same time, the 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 operating distance of the signal jammer when it is used indoors and outdoors?
Answer: Yes. The effective distance (10-40 meters) of the 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 operating 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 signal jammers, this factor should be fully considered to avoid shielding dead angles and thus affecting the shielding effect.
5. Does the signal jammer have the same 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 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 signal jammers in the field should be increased when necessary to ensure the shielding effect of CDMA mobile phones.
6. After the 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 terms of design, we use the thermal conductivity of the aluminum alloy wire-drawing chassis to assist in heat dissipation. So as to ensure stable work for a long time.
Therefore, the hot casing will not damage the machine.
