1. Why does the covered area still have a signal when the mobile phone signal blocker is turned on?

Answer: In fact, it shows a false signal. If you test it now, you can't get through. When someone uses a mobile phone to make a call, you can find that there is no signal mark on the signal indicator, and the mobile phone can no longer make a call.

2. Will the mobile phone signal blocker affect the operation of other electronic products?

Answer: First of all, it won't happen. The main reason is that the signal magnetic wave induction signal emitted by the mobile phone signal blocker completely falls into the national specified mobile phone working frequency band, which will block the mobile phone communication. In fact, this kind of signal is equivalent to being in a static state and will not affect other electromagnetic equipment. If there is a need to block the signals of other electronic equipment, the equipment can be customized.

3. The mobile phone signal blocker can effectively block the signal of the mobile phone, but will it cause harm to the human body?

Answer: In fact, for users, there is no need to worry about this kind of problem. The electromagnetic induction signal sent by the mobile phone signal blocker has a relatively weak compressive strength. Data tests show that the compressive strength of this kind of signal will not cause harm to the human body. At the same time, the full-band jammer only blocks the forward signal of the mobile phone, so that the mobile phone cannot communicate with the communication base station, so it will definitely not cause any damage to the mobile phone itself.

4. What are the differences in the effectiveness of using the mobile phone signal jammer outdoors or indoors?

Answer: Of course there are. The standard and reasonable working range of the cell phone signal jammer is (0-60 meters), which is the indoor distance. If it is actually outdoors, the distance will be greatly increased, and the effective shielding distance can reach between 300-500 meters. Here we must point out that whether it is used indoors or outdoors, the reasonable effectiveness +- distance of the shielding device has a certain relationship with the natural conditions of the year, such as the distance from the communication base station, the location of the installation, etc. Therefore, when using the full-band jammer, this factor should be taken into account to avoid the formation of shielding blind spots and thus affect the actual shielding effect.

5. Does the mobile phone signal jammer have the same effect on GSM mobile phones and CDM0A mobile phones?

Answer: This 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 full-band signal jammers for CDMA mobile phones is lower than that of GSM mobile phones, but the difference is not large, about 2-4 meters. However, users are also reminded to pay attention to some important places, and if necessary, the number of full-band jammers on the site should be increased to ensure the shielding effect of CDMA mobile phones. Because the signal strength of CDMA and GSM is different in the same on-site environment, the shielding distance achieved will also be different.

6. After the mobile phone signal jammer works for a period of time, the shell will heat up. Will long-term operation damage the device?

Answer: This is a normal situation. In terms of design, we just use the heat conductivity of the aluminum alloy brushed shell to help dissipate heat. The device itself has 4 built-in radiator fans and adopts a more professional air supply mode design, which can ensure long-term stable operation. Therefore, the heat of the shell will not damage the device.
