Is the interference range of mobile phone signal jammer to different frequencies the same?

Is the interference range of mobile phone signal jammer to different frequencies the same?

  • 2022-05-16

The mobile phone signal jammer can not only interfere with the mobile phone signal, but also realize the interference of radio signals in other frequency bands by adding interference modules in different frequency bands. As we all know, radio signals can achieve different functions according to the frequency used, including GPS, WiFi and so on. Because of different radio technologies and systems, as well as the difference in signal strength transmitted by the signal transmitting source of radio signals, the range of interference will be different when the mobile phone signal jammer interferes with these radio signals.

At present, the signal frequencies that domestic mobile phones can use range from 700m to 6000m, including the signals of mobile phone operators, WiFi signals, GPS signals, etc. according to the different signal frequencies, they are divided into various uses, and the functions they realize are also different.

The interference range of mobile phone signal jammer for mobile phone signals of different frequencies is also different. Under the same test environment, the mobile phone signal strength of each frequency band is also very different, but the mobile phone can receive mobile phone signals of multiple frequency bands at the same time according to different operators, so as to ensure that the mobile phone can be used normally. At this time, it is necessary to test the frequency band of the strongest mobile phone signal on site, Then, after adjusting the mobile phone signal jammer or adjusting the signal source, and then covering the mobile phone frequency band with the strongest on-site signal, we can basically determine the ability of the mobile phone signal jammer to interfere with all mobile phone signals on the site.

In specific cases, the cost of the above solutions is relatively high. In order to save costs and pursue higher cost performance, the following schemes can be considered:
Test the strong frequency band on the site, and then equip with high-power interference module to interfere with these strong signal frequency bands, so as to reduce the cost and achieve the purpose of interference effect.
