Can a mobile phone blocked by a full-band signal jammer be cracked?

In some occasions, such as meeting rooms, movie theaters and other places, in order to maintain order and a quiet environment, mobile phone signals are usually shielded. The most common and effective way to limit the use of mobile phones is to use a full band signal jammer to shield mobile phone signals. This device interferes with the mobile phone's reception of base station signals by emitting white noise signals at the same frequency as the mobile phone signal, making the mobile phone behave For no signal, limited service, etc. The shielding range of the full-band signal jammer depends on the transmit power of each module inside the device and the signal field strength of the base station on site. It can be seen that it is relatively difficult to crack the blocked mobile phone signal.

The cracking methods searched online may not be reliable, the following are some solutions provided by professional manufacturers. If you want to restore the mobile phone signal within the shielding range of the full-band signal jammer, there are only two ways: one is to take the mobile phone away from the coverage of the jammer, and the mobile phone signal will naturally recover; the other is to use The way to enhance the power of the base station’s transmitted signal is within the shielding range of the full-band signal jammer. If you want to use the mobile phone normally, you have to increase the power of the base station’s transmitted signal, thereby causing the signal of the mobile phone within the shielded range to increase. This method is more difficult and requires multi-faceted consideration.

So, can the problem be solved through a series of mobile phone operation settings mentioned on the Internet, such as changing the network setting to manual search? Actually not. Regardless of whether the network is automatically searched or manually searched, it needs to be connected to the base station for communication in the end. Therefore, after the actual operation of these two methods, the mobile phone still cannot receive the signal.

To sum up, it is not easy to crack the signal limit of the full-band signal jammer, and it requires professional knowledge and skills. For ordinary users, it is best to abide by the site regulations, and do not try to crack the mobile phone signal shield, so as to avoid unnecessary disputes and safety issues.
