Common problems of mobile phone signal shield

　　Common problems of mobile phone signal shield

　　(1) When the signal shield of a mobile phone works, why does the signal indicator of a mobile phone still show a signal?

　　A: it's just a cover. In fact, mobile phones were no longer able to communicate. If you press the button at will, you will find that there is no signal indicator on the signal indicator.

　　(2) Can the signal shielding of mobile phones interfere with the normal operation of other electronic devices?

　　A: No. This is because the electromagnetic signal sent out by the mobile phone signal circuit breaker is completely controlled in the national mobile phone working frequency band, which will only cut off the mobile communication. In addition, the signal will not affect the electronic equipment, always in a relatively static state.

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

　　A: users can rest assured that the electromagnetic signal strength transmitted by the mobile phone signal shielding is very weak, so the test data shows that the signal strength is far from harmful to human body. On the other hand, mobile phone signal shielding will only block the front signal of the mobile phone, and the mobile phone can not contact the base station, so it will not cause any damage to the mobile phone itself.

　　(4) Is there any difference in the effective shielding distance between the indoor and outdoor shielding devices of mobile phones?

　　A: Yes. The effective shielding distance (30-40m) of the mobile phone signal mask generally refers to the indoor distance. In outdoor open area, the effective distance of shelter can reach hundreds of meters. Whether it is used indoors or outdoors, please note that the effective shield operating distance is related to the distance from the base station and the setting place. Therefore, in the use of mobile phone signal shielding, we need to take full account of its main reasons, to avoid the blind angle of shielding effect on the shielding effect.

　　(5) Is the shielding effect of mobile phone signal shielding device on GSM mobile phone and CDMA mobile phone the same?

　　A: I often listen to this question. The anti-interference performance of CDMA mobile phone is far superior to that of GSM mobile phone, so the effective shielding distance of CDMA mobile phone signal shielding is smaller than that of GSM mobile phone, and the difference is not big, about 2-4 meters. However, in some special important places, the number of mobile phone signal shielding devices should be increased if necessary, and users should ensure the shielding effect of CDMA mobile phones.

　　(6) Will cell phone signal shielding damage the machine? After working for a long time, the machine became hot.

　　A: Thank you for your reminder. This is normal. In the design, the heat conduction of fan and aluminum is used to help heat dissipation. Therefore, it can ensure long-term and stable movement. Therefore, even if the cabinet is ironed, the machine will not be damaged.

　　(7) Can a mobile phone with an antenna block the signal? Lock antenna? Can cell phone signal shielding be placed freely?

　　A: before turning on the power of the equipment, the antenna must be installed with the identification number corresponding to each channel on the equipment. Since the effective range of the shield is a circular area centered on the shield, the layout position of the shield can be correctly selected and used, so as to avoid the dead corner of the shield.
