Why is there still a signal on the phone's signal indicator when it works?
A: It's just an illusion.In fact, the mobile phone has been unable to communicate.When you press the pull button, you will find that there is no signal on the signal indicator.The cell phone signal shield will not interfere with the normal work of other electronic devices. The antenna should be installed on the corresponding signs of each channel on the host, and then connected to the host power supply.
The effective coverage of the shield is a circular area centered around the shield, so be careful to choose the location of the shield so as to avoid blocking the dead Angle?
A: No.This is because the electromagnetic signal emitted by the cell phone's signal shield is completely within the country's mobile operating band, which only blocks mobile communication.And this signal is always in a relatively static state, and will not affect any electronic equipment.
Are cell phone signal Jammer harmful to people and mobile phones?
A: Please rest assured that the electromagnetic signal intensity emitted by the cell phone signal Jammer is very weak. The test data indicates that this signal strength is far from harmful to the human body.At the same time, the mobile phone signal shield is just blocking the forward signal of the phone, so that the cell phone cannot be connected with the base station, so there will be no damage to the phone itself.
Is there any difference between the effective shielding distance of the mobile phone signal shield in indoor and outdoor use?
A: There are.The effective shielding distance (30-40 meters) of the cell phone signal shield is generally referred to as indoor distance.In open areas, the effective distance of shielding can be several hundred meters.It should be noted, whether they are within the room, or in outdoor use, effective shielding effect of shielding distance has relationship with environmental conditions, such as from the base station near and far, placed, etc.Therefore, when using cell phone signal shield, this factor should be fully taken into account to avoid blocking the dead Angle and thus affect the shielding effect.
Is the cellular signal shield the same for GSM mobile phones and CDMA mobile phones?
A: that's a good question.Because CDMA mobile phone's anti-interference performance is far superior to that of GSM mobile phone, the effective shielding distance for CDMA mobile phone is smaller than that of GSM mobile phone, but the difference is not very large, about 2-4 meters.But it also reminds users to pay attention to some particularly important sites, and should increase the number of mobile phone signal blockers when necessary to ensure the shielding effect of CDMA mobile phones.
After working for a period of time, the mobile phone signal mask is hot. Will working long hours damage the machine?
A: thank you for your care. This is a normal phenomenon.In the design, we use the thermal conductivity of aluminum alloy to assist the heat dissipation.This can guarantee long time stable work.As a result, the machine will not damage the machine.
