Is the method of cracking the cell phone signal jammer searched online reliable? from dojammer's blog

In some places where the use of mobile phones is restricted, the most common operation method is to install a cell phone signal jammer. However, there are always a small number of people who think about how to crack the cell phone signal jammer so that their mobile phones can be used normally. So are the methods of cracking the cell phone signal jammer searched online reliable?

If you want to crack the cell phone signal jammer, you must first understand the working principle of the mobile phone signal jammer. The working principle of the cell phone signal jammer is to transmit a white noise signal with the same frequency as the mobile phone signal, thereby interfering with the mobile phone receiving the signal of the base station. The mobile phone shows no signal, limited service, etc. The size of the shielding range of the mobile phone signal jammer depends on the transmission power of each module of the cell phone signal jammer and the signal field strength of the base station at the site of use. In theory, the greater the transmission power of the mobile phone signal jammer, the greater the shielding range. The stronger the signal from the base station to the site of use, the smaller the shielding range of the mobile phone signal jammer.

From the principle of the cell phone signal jammer, it is still difficult to crack the cell phone signal jammer. Of course, there are still methods. The cracking methods searched online are completely useless. Here is an introduction to the cracking method of the cell phone signal jammer for reference only.

Without damaging the cell phone signal jammer, if the mobile phone is within the shielding range of the jammer, there are only two ways to restore the mobile phone signal. One is that the mobile phone leaves the shielding range. When the mobile phone leaves the coverage range of the jammer, the mobile phone signal will naturally be restored. The other is that the signal strength of the base station is enhanced without leaving the coverage range of the jammer, so that the shielding range of the cell phone signal jammer can be reduced, and the mobile phone signal can be restored at this time. Of course, this operation is also difficult. Building a base station must be demonstrated, and the strength of the mobile phone signal emitted by the base station is not something you want to enhance.

The Internet says that through the mobile phone settings, change the network settings to manual search and adjust the mobile phone receiving frequency to increase. These two methods are obviously not credible.
