Therefore, cell phone signal jammers have come into everyone’s sight. We have learned that cell phone signal jammers are used by candidates to cheat on their mobile phones. I believe that anyone who has experienced a major exam is familiar with it. Before the exam, I heard that a cell phone signal jammer may be installed in this examination room.

Jammers can not only be used in student dormitories, examination rooms, office conference rooms, but also on mobile phone screens. With the progress of society and the development of technology, jammers have become an indispensable part of people's lives, and are very useful for primary school students and middle school students. In particular, signal jammers are an important factor affecting their speech. Playing with mobile phones for a long time will affect eyesight, and more seriously, it will affect children's learning. Therefore, there will be a jammer in the dormitory to prevent students from staying up while playing with mobile phones at night and affecting their sleep.

For many families, their children are addicted to online games and various video software. Parents are very distressed, so they put signal jammers in their children's rooms to prevent their children from making phone calls when they are not sleeping and delaying their studies. As screens become more common, everyone is worried about whether cell phone signal jammers will also affect base station signals, or even cell phone signals.

Under normal circumstances, mobile phone signal jammers will not affect base stations. The greater the power of the signal jammer, it will also have an impact on residents' lives, and the power of the signal jammer will not be too large. For families, they generally choose to use lower frequency signal jammers and place them in places that need to be shielded. Penetrating through walls will also weaken the shielding effect, so it will not affect neighbors.

Its basic principle is to connect the communication between mobile phones and base stations through radio waves within a certain frequency range, and complete the transmission of data and sound at a certain rate and frequency. During use, the cell phone signal jammer will scan signals from low-end frequencies to higher-end frequencies at a certain speed. Therefore, the scanning speed will cause garbled interference to the information signal received by the mobile phone, making it impossible for the mobile phone to receive normal data from the base station and unable to establish a connection with the base station, causing problems such as network search, no signal, and no service, which seriously affects the transmission of mobile phone signals.
