How wifi jammers interfere with your signal?

Every year during the college entrance examination, the school will have network problems, such as mobile phone disconnection and slow Internet access, because the school has turned on the wifi jammer. If we think of cell phones as hand-held two-way radios, radios are subject to interference, and cell phones are no exception. Like a radio, the signal is jammed.

How wifi signal jammer interfere with mobile phones?

Interfering with a cell phone is like interfering with any other type of radio communication. A mobile phone communicates with its service network through a base station. When a cell phone user drives down the street, the signal switches from one base station to another.

The frequency ranges of the three major operators

We know that wireless communication uses electromagnetic waves to communicate. The functional properties of electromagnetic waves are determined by their frequency. Our mobile phones must emit qualified electromagnetic waves in order to connect to our telecommunications carrier base stations. Different communication systems use different frequencies, so everyone is calm and doesn't interfere with each other. The basic principle of a wifi jamming device is to emit the same radio frequency as a cell phone. Since the frequency is the same, the mobile phone cannot distinguish which signal is the normal base station signal, thus achieving "interference".
