In some places where the use of mobile phones is restricted, the most common method of operation is to install a mobile phone signal blocker. However, there are always a small number of people thinking about how to crack the mobile phone signal blocker so that their mobile phones can be used normally. Is the shield method reliable?
If you want to crack the cell phone signal jammer, you must first understand the working principle of the cell phone signal jammer. The working principle of the cell phone jammer is to emit a white noise signal with the same frequency as the cell phone signal, thereby interfering with the signal received by the cell phone from the base station, and the performance of the cell phone. For no signal, restricted service, etc. The shielding range of the mobile phone signal shielding device depends on the transmission power of each module of the mobile phone signal shielding device and the signal field strength of the base station in use. In theory, the greater the transmitting power of the mobile phone signal shielding device, the larger the shielding range. , the stronger the signal from the base station to the use site, the smaller the shielding range of the mobile phone signal jammer.
From the perspective of the principle of mobile phone signal jammers, it is still relatively difficult to crack the mobile phone signal jammer. Of course, there are still methods. The cracking methods found on the Internet are completely useless. The following is an introduction to the cracking method of the mobile phone signal jammer, for reference only.
Under the premise of not destroying the mobile phone signal shielding device, if the mobile phone is within the shielding range of the shielding device and wants to restore the mobile phone signal, there are only two ways. The cell phone signal naturally recovered. The other is to not leave the coverage of the jammer, but to increase the signal strength of the base station, thereby reducing the shielding range of the cell phone signal jammer, and then the cell phone signal can be restored. Of course, this kind of operation is also more difficult. Building a base station requires proof, and the strength of the mobile phone signal emitted by the base station is not what you want to enhance.
As mentioned on the Internet, through the mobile phone settings, change the network settings to manual search, and adjust the mobile phone reception frequency to increase. Both of these methods are obviously not credible.
