Does a cell phone jammer harm mobile phones? The answer is no. Cell phone jammers will not harm mobile phones, and will not increase the malfunction of mobile phones, nor will it reduce the service life of mobile phones. The signal frequency emitted by the cell phone jammer is white noise with the same frequency as the mobile phone, which is equivalent to the interference signal of...

There is no need to avoid the radiation hazard of cell phone signal blockers. Like cell phones,cell phone signal blockers do have certain radiation. The working principle of cell phone signal blockers is similar to that of cell phones. For example, the chip it uses is the same as that ofcell phones, and it also emits electromagnetic signals. Therefore, like cell phones, it will also...

In some places where the use of mobile phones is restricted, the most common operation method is to install cell phone signal jammers, and there are always a small number of people who think about how to crack mobile phone signal jammers so that their mobile phones can be used normally. So are the methods of cracking mobile phone jammers searched online reliable? If you want to crack a...

Mobile phone jammers can not only interfere with mobile phone signals, but also interfere with radio signals in other frequency bands by adding interference modules of different bands. Everyone knows that radio signals can achieve different functions according to the different frequencies used, including GPS, WiFi, etc. Because of the differences in radio technology and standards, as well as...

As the name suggests, the cell phone signal jammer is a professional device that can interfere with mobile phone signals. It is used in many places, such as school examination rooms, libraries, courts and hospitals, etc. So how to use the jammer better? Here is a brief introduction.
