Admin Posted on 2022-10-24

The 5G wifi jammer has become the standard test equipment in the test room. Not only the high school entrance examination, but also the postgraduate examination, the civil service examination, and various qualification examinations require wifi jammer devices to prevent candidates from contacting the outside world through wireless signals. In the examination room using wifi signal jammer, various mobile phone signals (2345G), wireless intercom signals, Bluetooth WiFi signals, etc. will be blocked by interference.

Why wifi signal jammer can interfere with your signal?

So let's talk about the wifi signal jammer, why can it interfere with your mobile phone signal?

For the time being, we can compare mobile phones to radios. Radios often have channels that are confused and inaudible, that is, the signal is interfered with. Since radios can be jammed, so can cell phones, either naturally or through some devices.

There are many different names for wifi jammers, such as wifi blockers, wifi scramblers, and wifi disruptors.

5g wifi frequency jammer

For the uplink and downlink channels of the mobile phone system, techniques such as frequency multiplication, frequency division, and frequency hopping filtering are used to analyze the required shielding frequency. According to the power of the wifi jammer device, a spherical shielding space is customized, and a shielding magnetic field is automatically formed within the specified range so that the mobile phone in this space loses the signal. When the 5G wifi jammer is in a working state, the function of sending and receiving signals of mobile phones within the specified range can be disabled, and it cannot be dialed out or dialed in, so as to achieve the purpose of forced disabling.
