The basic principle of mobile phones (wireless communication) is shown as follows: In a certain output power area, the mobile phone and the communication base station are connected by radio waves, and the data information and sound effects are transmitted with a certain baud rate and configuration method. In view of the above communication principles, the wifi jammer migrates to the high-end scanner with a certain output power during the operation. The speed of the scanner can cause harm to error codes when the mobile phone receives the data signal in the message format. The mobile phone cannot detect the basic data information transmitted from the communication base station, so the mobile phone cannot establish a connection with the communication base station. The specific performance of the mobile phone is the search network, poor mobile phone signal, and no service system.
With a wifi blocker, why is there a situation of cheating?
Generally speaking, in the whole process of the test, the mobile phone is like a brick, and it can't be used at all. Since there are some force majeure events, they must be analyzed differently. Some people described the situation in Wuhan last year that the 5G signal blocking occurred at that time. Security loopholes, because 2G, 3G, 4G, and 5G, the frequency bands of such data signals are different, 5G has just been commercialized, and many wifi signal jammers are compatible with 5G signal shielding, so they have certain security loopholes.
Generally speaking, in the college entrance examination, the mobile phone is like a brick and cannot be used at all. Even if there are some force majeure events, it must be analyzed differently. Some people described the situation in Wuhan last year that 5G signal blocking occurred at that time. Because 2G, 3 G, 4G, and 5G, the frequency bands of such data signals are different, 5G has just been commercialized, and many wifi jammer devices are compatible with 5G signal shielding, so they have certain system software probability.
In addition, there is also other dedicated wireless communication equipment. The frequency band and data signal frequency band of such facilities are not in the same range, so the wifi frequency jammer cannot function, and in order to prevent some people from using it Such machines and equipment are fraudulent, and the test site will continue to be equipped with data signal detection vehicles. Once detected, the signal source will be locked immediately, and then the waiter will come to the door to arrest.
