Handheld Cell Phone Scrambler
The principle of the mobile phone signal jammer: within a certain frequency range, the mobile phone and the base station are connected through wireless electromagnetic waves, and the data and sound transmission is completed with a certain baud rate and modulation method. The communication principle of the mobile phone signal jammer, the Handheld Cell Phone Scrambler scans from the low end frequency of the forward channel to the high end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena. Now that we know that the communication method of wireless communication is to communicate using electromagnetic waves. The functional characteristics of electromagnetic waves are determined by their frequency. cell phone jammer
