How do wifi jammers work? How does it interfere with cell phone work?

Hi, can you explain in detail how the wifi signal blocker works, how does it interfere with the wifi cell phone signal?

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 cell phone jammer is to emit the same radio frequencies as cell phones. Since the frequency is the same, the mobile phone cannot distinguish which signal is the normal base station signal, thus achieving "interference".
