Why can mobile jammer block your mobile phone signal
During the annual college entrance examination, the school is equipped with mobile jammers, so there are network problems such as mobile phone dropping and slow internet speed
Why do mobile jammers block their cell phone signals? This is because our mobile phones must transmit qualified electromagnetic waves in order to connect to our communication operator base station. The functional characteristics of electromagnetic wave are determined by frequency. When the mobile jammer works, it transmits the same RF signal as the mobile phone. Due to the same frequency, the mobile phone can not distinguish which signal is the signal of the base station, so as to realize "shielding".
