How does the frequency jammer interfere with the normal use of mobile phones?

  • 2023-01-08

Up to now, with the increase of mobile phone users, the need for some jammers has become more and more. Nowadays, the frequent use of mobile phones will inevitably encounter some confidential places where it is forbidden to call, send information and surf the Internet. Frequency jammers have always been able to operate in these places and are excellent jamming tools. How do they interfere with the normal use of mobile phones?

At present, when we use mobile phones to make calls, we use the uplink frequency to get in touch with the base station, and then the signals of the base station can be used to make calls from the operator to the mobile phone. When the mobile phone is in standby, the mobile phone still keeps in touch with the base station through the uplink signal. Once there is a call demand, the mobile phone call and information transmission can be realized through the operator at any time. The frequency jammer is a device that interferes by sending the same signal frequency. If the mobile phone shows no signal when the jamming device is turned on, the jamming is successful.

Today's frequency jammers can not only interfere with mobile phone signals, but also interfere with GPS positioning signals, and their functions are becoming more powerful. There are different types of jammers sold on the market at present. Some devices can interfere with single terminal signal frequency, while some frequency jammers can interfere with multiple signal frequency bands at the same time. The former has a single interference frequency band and a more comprehensive interference effect, while the latter has a variety of interference signals and more interference signal frequency bands, which can be selected according to their own needs.
