cell phone jammer

The principle of the mobile phone jammer: within a certain frequency range, the mobile phone and the base station are connected by wireless electromagnetic waves, and the data and sound transmission is completed through a certain baud rate and modulation method. The communication principle of the mobile phone signal jammer, in the working process, the mobile cell phone jammer scans from the lower frequency of the forward channel to the high end at a certain speed. This scanning speed causes garbled interference to the message signal received from the cellular phone, and the cellular phone cannot recognize normal data sent from the base station, so the cellular phone cannot connect to the base station. The mobile phone showed signs of searching the network, no signal, no service system, etc. Now we know that the communication method of wireless communication is communication with electromagnetic waves. The functional characteristics of electromagnetic waves depend on their frequency.
