6 common questions about mobile phone jammers

1.Why is there still a signal within the coverage area after the mobile phone signal blocker is turned on?

Answer: In fact, there is a signal on the surface, but it is actually a false signal. The mobile phone will not be connected. When someone calls, they will find that the mobile phone signal indicator disappears and they cannot make a call.

2.Will the mobile phone signal blocker interfere with other electronic devices?

Answer: Generally not, mainly because the signal emitted by the mobile phone signal blocker is completely within the official mobile phone working frequency band, which blocks the mobile phone communication. This signal is static in nature and will not affect other electromagnetic devices. If you need to block the signals of other electronic devices, you can customize the device.

3.Will the mobile phone signal blocker cause harm to the human body?

Answer: Users don’t have to worry about this problem. The electromagnetic induction signal emitted by the mobile phone signal blocker is relatively weak. Data tests show that the signal strength is far from the level of causing harm or damage to the human body. Moreover, the full-band blocker only blocks the signal sent out by the mobile phone, so that the mobile phone cannot communicate with the base station, so it will not cause harm to the mobile phone itself.

4.Is there a difference in the effect of using the mobile phone signal blocker indoors and outdoors?

Answer: There is a difference. The standard optimal working range of Cell Phone Jammers is generally 0-60 meters, which is suitable for indoor use. When used outdoors, the effective shielding distance can be greatly increased to between 300-500 meters. It should be noted that whether used indoors or outdoors, the effective shielding distance of the jammer is affected by many factors such as the distance from the communication base station and the placement of the equipment. Therefore, these factors should be considered when using a full-band jammer to avoid the creation of a shielding blind area and affect the actual effect of the jammer.

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

Answer: This is a good question. Since CDMA mobile phones have superior anti-interference characteristics compared to GSM mobile phones, the effective shielding distance of full-band jammers for CDMA mobile phones is slightly smaller than that of GSM mobile phones, but the difference is not large, generally around 2-4 meters. However, attention should be paid to key locations, and if necessary, the number of full-band jammers in a specific area can be increased to ensure effective shielding of CDMA mobile phones. In the same local environment, the signal strength of CDMA and GSM may be different, resulting in different shielding distances.

6.After long-term use, the shell of the mobile phone signal blocker may heat up. Will continuous use damage the device?

A: This is normal. The device is designed with a brushed aluminum alloy shell to dissipate heat. The device has 4 built-in cooling fans and adopts a professional air supply design to ensure long-term stable operation of the device and is not easily damaged by the heat of the shell.
