Build A Homemade Cell Phone Scrambler
A jammer is a device that transmits signals at the same frequency. If the shielding is turned on, the interference part succeeds when the area of the mobile phone signal is disabled. Mobile users are becoming more and more popular nowadays, so mobile phone jammers are more common than electronic devices to disable mobile signals in specific locations. Build A Homemade Cell Phone Scrambler Is an instrument used to protect cellular phones from receiving signals. The mobile jamming device broadcasts the same frequency signal to the GSM modem. If the mobile phone signal is disabled with the mobile jammer enabled, the jamming is considered successful. A cellular phone is a full-duplex device that can use two frequencies at the same time. One is talking, the other is listening. The signal is processed at the same time. Signal jammers can only block one of these frequencies at a time, which causes both frequencies to be blocked because the phone thinks that there is no service in this area because only one of them can be obtained. cell phone jammer
