A signal jammer is a kind of equipment that is commonly used in examination rooms, schools, governments, finance and other places in life. It is forbidden for those present to use communication equipment such as mobile phones. A communication device without a signal is almost useless, so how to turn off the signal jammer?
The principle of signal jammer: The signal jammer scans from the low end to the high end at a certain frequency, interfering with the receiving base station information of the communication equipment, thus causing the communication equipment to have no network and other phenomena. Generally, the interference range is about 40 meters.
The closing of the wifi signal jammer is generally carried out by the opening mechanism. Under normal circumstances, the jammer is forbidden to be used. It is only necessary to turn off the power of the jammer. The following methods are only for breaking through the signal jammer in special circumstances, and should not be used under normal circumstances.
Number segment cracking method: Under normal circumstances, the signal blocker shields the old number segment. Generally, the number segment just released by the communication company, the signal blocker is too late to integrate, and naturally it will not play the role of shielding. This method is a fluke.
wifi method: The mobile phone signal blocker is only for blocking the signal of the mobile phone, not for the wifi. If you can connect to the surrounding wifi, you can communicate with the outside world with the help of various communication software, that is, break through the shielding.
Bluetooth cracking method: When two communication devices are close enough, Bluetooth can also be used to connect, which can be used to transfer files, and the information is written in the file to break through the signal shielding.
Walkie-talkie: Generally speaking, the signal jammer shields the signal transmission within a certain range and a certain band. We can use the walkie-talkie to communicate with the outside world by relying on different bands and channels, thereby bypassing the shielding of the wireless wifi bluetooth jammer.
