Wireless communication is the application of electromagnetic waves to contiue communication. The functional characteristics of electromagnetic waves are determined by its frequency. Our mobile phone must launch the electromagnetic wave that meets the request and connect to our communication carrier base station. Therefore, the fastest prevention of shielding wireless communication is to disruptor phone signal reception.
The basic principle of the cell phone jammer is to transmit the same radio frequency band as the mobile phone. Since the frequency band is the same, the mobile phone can't tell which signal is the real base station signal, thus completing the "interference". This multi-network signal disruptor, in a cyclic manner, repeatedly plays the interference band corresponding to this signal, masking multiple bands at once, and the distance of this cycle is so small that the phone can basically sit down without speaking. Nowadays, the most common one on the market is the handheld cell phone signal jammers.
