Block Diagram And Working Of Cell Phones To Solve Frequency Problems

Technology is advancing by leaps and bounds. Block Diagram And Working Of Cell Phones Catching up with the development of communication technology to the 2G era, cell phone signal jammers can work perfectly. At that time, most operators used the same frequency band, and the frequency was relatively fixed, so it was relatively easy to interfere with it. After the addition of 3G and 4G, the diversification of signal frequency bands follows the rapid progress of communication technology. 3G and 4G communications were quickly applied to practical scenarios. At this time, the mobile phone signal jammer encountered a dilemma, that is, the signal interference originally designed only for 2G, because of the frequency, it could not cover the 3G and 4G signals. This also renders the mask ineffective. In this case, the development of communication technology began to force the simultaneous development of shielding technology. In order to be able to interfere with 3G and 4G signals, cell phone signal jammers quickly evolved the interference function specifically for 3G and 4G frequency bands. So there is a problem that 2G, 3G and 4G all need to be shielded, so how? What about blocking all three frequency bands at the same time and space? The eight-antenna mobile phone jammer can shield 2G/3G/4G at the same time. The answer is very simple. It is to repeatedly play the interference bands corresponding to the three signals in a loop to cover the three bands at one time, and the interval of this cycle is very small, so that the mobile phone There was no chance to speak at all, so I could only sit down obediently.

Due to the frequent occurrence of all kinds of middle and senior middle school students using mobile phones to send text messages during class time, the trouble and noise brought by mobile phones in serious places such as government agencies and enterprises, large, medium and small conference rooms, concert halls, theaters, etc. It is also relatively common, especially with the development of the mobile game industry, many college students play games in the dormitory until the middle of the night, which brings great trouble to the roommates' reasonable rest. More and more people are realizing the importance of using Block Diagram And Working Of Cell Phones to keep themselves from being disturbed. This has also prompted more people to pay attention to small hand-held mobile phone signal jammers. What are the advantages of the small handheld cell phone jammer ? First of all, the reason why it is a small handheld signal jammer must be smaller, so it is easy to carry and convenient for us to use when going out, on business trips, or when we need a concealed signal jammer.
