Can the mobile phone shielding device fail without destroying the mobile phone shielding device?
If you want to make the cell phone jammer fail, you must first know the working principle of the cell phone jammer and how the cell phone jammer makes the cell phone no signal.
The principle of the cell phone jammer is to emit white noise interference signals with the same frequency as the cell phone signal. When the signal strength emitted by the cell phone jammer is stronger than the signal transmitted by the base station to the site at the site of use, then the cell phone signal will be completely blocked. If the signal emitted by the mobile phone shielding device is covered, the mobile phone will show no signal, or the service will be limited. According to this principle, the mobile phone jammer is more suitable for this name.
How can the mobile phone still have a signal without destroying the mobile phone jammer? Here are two methods.
First, reduce the power supply voltage of the mobile phone shielding device. The mobile phone shielding device generally needs to be connected to the AC 220V mains. The mobile phone shielding device has a power adapter or switching power supply, which is converted into DC power. The wide-voltage power supply also needs 85-265V or 100-265V. If you want the mobile phone shield to fail, you can reduce the power supply voltage to below 85V or above 265V. Of course, this method is generally not very easy to implement. Professionals are required to operate, and safety precautions are required during operation.
Second, it can increase the signal strength of the mobile phone at the scene, so that the signal strength of the mobile phone on the scene is higher than the signal strength emitted by the mobile phone jammer, and it can also make the mobile phone jammer fail. This method requires the help of a mobile phone signal amplifier and a mobile phone signal amplifier. A receiving antenna is needed, the location of the receiving antenna, and the coverage of the signal transmitted by the mobile phone signal jammer can be used to receive the mobile phone signal normally, otherwise it will still be interfered by the mobile phone jammer. Then place the transmitting antenna of the mobile phone amplifier on the use site of the mobile phone jammer.
