Is the shielding range of electronic jammers the same for mobile phones of different standards?
Electronic jammers can not only block mobile phone signals, but also achieve interference from radio signals in other frequency bands by adding interference modules in different frequency bands. Everyone knows that wireless signals can achieve different functions based on the frequency used, including GPS, WiFi, and so on. Due to differences in radio technology and standards, as well as differences in signal strength emitted by radio signal emission sources, electronic jammers can interfere with these radio signals, resulting in different interference ranges.
At present, the signal frequencies that domestic mobile phones can use range from 700M to 6000M, including signals from mobile operators, WiFi signals, GPS signals, etc. According to the different signal frequencies, they are divided into various purposes and the functions implemented are also different.
The interference range of electronic interference machines for mobile phone signals of different frequencies is also different. In the same testing environment, the signal strength of mobile phones in different frequency bands also varies greatly. However, depending on the operator, mobile phones can receive multiple frequency bands of mobile phone signals at the same time to ensure their normal use. At this time, it is necessary to test the frequency band of the strongest mobile phone signal on site, and then adjust the electronic interference machine or signal source, Then cover the strongest mobile phone frequency band on site, and basically determine the ability of this electronic jammer to interfere with all mobile phone signals on site.
In specific circumstances, the cost of the above solution is relatively high. In order to save costs and pursue higher cost-effectiveness, the following options can be considered. Test out strong frequency bands on site and equip them with high-power interference modules to target these strong signal frequency bands, thereby reducing costs and achieving interference effects.
