Nowadays, telephone jammers are used in many places, such as conference rooms, detention centers, schools and other places. However, the types of jammers used in different places are different. Do you know how to distinguish them?

Many people know the telephone jammer, but they don't know how it works. After these jamming devices are used, the mobile phone can't search for signals, and naturally it can't be used any more. The mobile phone can access the Internet because it can receive the wireless signal sent by the base station. Its own function is mainly to transmit a section of electromagnetic wave signal through itself, so as to interfere with the mobile phone's reception of the base station signal. In this way, the mobile phone cannot access the Internet, so as to achieve the effect of signal interference. So before choosing, you need to know which signals you want to interfere with. Generally, 2G to 5G mobile phone signals can be interfered with. If you want to interfere with which signal segment separately, this can be set at the factory.

For the places where these telephone jammers are used, if they are used indoors, they are generally used in the examination room, conference room and other places, and small power jammers can be selected. If it is an outdoor open area, a high-power jammer must be used to cover the required range because of its wide range.
