Have you heard of a cell phone jammer? You may not be familiar with this product, but you definitely use mobile phones often, and jammers are products that block radio signals from electronic products such as mobile phones, GPS WIFI, and Bluetooth. More specifically, the mobile phone signal jammer suppresses communication from mobile phones and the like, and transmits interference waves in the same frequency band as the frequency bands used by the mobile phone and PHS, reducing the condition of radio waves sent from the base station received by the mobile phone, which can prevent the Use your phone nearby.
The electromagnetic signal emitted by the mobile phone signal jammer only blocks the role of mobile communications, and thus is completely within the working frequency band of the national mobile phone. And the signal is always relatively static and has no effect on electronic equipment. Suitable for CDMA (China Unicom), GSM (China Mobile, China Unicom), SCDMA (Netcom Taitung), DCS (1800MHz), PCS (1900MHz), PHS (Telecom PHS), 3G, 4G, Wifi and other mobile phone signal shielding Bluetooth / 2.4G communication, wireless network signal GPS interference electromagnetic field strength is far lower than national standards, and has no impact on the human body.
It is normal for the cell jammer to not harm the machine after a long period of work. In design, we use aluminum alloy wire drawing machine to heat. Therefore, various signal interception equipment such as 3G / 4G jammers can ensure long-term stable work. Therefore, the machine will not damage the hot machine, and at the same time, the built-in industry standard switching power supply communication suppression device can ensure the stability of the signal!
