In fact, mobile phone jammers are no longer a new thing abroad, and they have begun to be sold on the Chinese market in the past two years. Some radio enthusiasts have even developed a set of design drawings and published them on the Internet. The principle is actually very simple. In layman's terms, it is like "speaking loudly than talking softly."

Regarding the working principle of this equipment, there is such a professional description: "The working principle of a mobile phone is that within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed at a certain baud rate and modulation method. For this communication principle, the mobile cell phone jammer scans from the low end of the forward channel to the high end at a certain speed. This scanning speed can cause garbled interference in the message signal received by the mobile phone, so the mobile phone cannot detect the signal sent from the base station. With normal data, no connection can be established with the base station."

Since it only interferes with the downlink signal, this kind of mobile phone jammer device will not affect the mobile base station or the normal use of other electronic devices. Therefore, in the propaganda of the merchants, this equipment is called: "Adopting foreign advanced technology, mainly for small places at home and abroad that require safety and confidentiality, such as private bosses, confidential offices, negotiation rooms, mobile vehicles, mobile Political and business dignitaries guard the scene, etc., and carefully developed high-tech products based on the actual situation of mobile communications at home and abroad... Give you a security and a peace."
