In some special occasions, the use of mobile phones is restricted. The most common is that the signal jamming installed on the site are blocked. There will always be some people thinking about how to crack their mobile phones so that their mobile phones can be used normally. Is it really feasible to crack the small tricks of online search?

If you want to break the signal jamming, you must first understand the working principle, that is, to transmit white noise signals with the same frequency as the mobile phone signal, thereby interfering with the signal received by the mobile phone from the base station. The mobile phone shows no signal and restricts service. The size of the interference range of the equipment depends on the transmission power of each module inside the equipment and the signal field strength of the base station on the site. Theoretically, the larger the shielding transmission power of the mobile phone signal, the larger the interference range. The stronger the signal from the base station to the site, the smaller the shielding range of the equipment.

From the perspective of principle, it is still difficult to crack, and there are still some methods. The cracking methods found on the Internet are completely infeasible.

The professional manufacturer introduced the cracking method to me, for your reference only

Without damaging the machine itself, if you want to recover the mobile phone signal within the interference range of the equipment, there are only two ways. One is that the mobile phone leaves the shielding range, and the mobile phone leaves the coverage range of the shielding device, and the mobile phone signal automatically recovers. The other is to enhance the signal strength of the base station without leaving the coverage range of the equipment, so as to narrow the interference range of signal blocking. At this time, the mobile phone signal is restored. Of course, this kind of operation is difficult. The establishment of a base station requires cooperation in many aspects. Moreover, the strength of the mobile phone signal transmitted by the base station is not something that an individual wants to enhance. It is a multi-dimensional consideration.

What the network says is to change the network settings to manual search through mobile phone settings, and adjust the mobile phone reception frequency to increase. These two methods are actually operated, but the mobile phone still has no signal
