Effectively shield Docomo, Softbank, AU, eMobile, WILLCOM, 3G mobile phone signals, 4G mobile phone signals, 24GWIFI, 5.8GWIFI, UHF, VHF walkie-talkie signals and other mobile communication signals. The principle of wireless communication: In a specific frequency range, the mobile phone and the base station are connected by radio waves, and the data and voice transmission are completed at a specific baud rate and modulation method. The interference device, the communication principle of the mobile WiFi jammer, scans from the low-end frequency of the forward channel to the high-end at a specific speed during the working process. This scanning speed will cause garbled interference in the SMS signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, so the connection between the mobile phone and the base station cannot be established. The mobile phone is manifested as a search network, no signal, no service system and other phenomena.
