How does a signal jammer interfere with mobile phone signals?

  • 2022-10-16

Mobile phone has become one of the necessary tools in our travel, on the contrary, the demand for mobile phone signal jamming equipment has gradually become more and more. When we use a mobile phone to make a call, we use the uplink frequency to contact the base station, and then the signal of the base station is sent to the mobile phone through the operator to realize the call function. 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 signal jammer is a device that interferes by sending the same signal frequency. If the mobile phone shows no signal when using the signal jammer, the jamming is successful. Nowadays, with the increasing number of mobile phone users, it is inevitable that some places will be prohibited from making calls, sending messages and surfing the Internet, and the signal jammer has become a very useful tool in these places.

Today's signal jammers can not only interfere with mobile phone signals, but also interfere with GPS positioning signals. Their functions are becoming more powerful. There are different types of jamming devices sold in the market at present. Some devices can interfere with single terminal signal frequency, while others can interfere with multiple signal frequency bands at the same time. The former has a single interference frequency band and more specialized interference effect, while the latter has more types of interference signals and more complete interference functions. Jamming equipment of different frequency bands can be selected according to requirements.
