Faraday Cage To Block Cell Phone Signal
When the cell phone battery starts, when the ringer rings, it can generate enough energy to cause a slight spark that can cause a fire. Relevant departments such as petroleum, chemical industry, safety, etc., have expressly stipulated that the use of mobile phones in oil depots is prohibited. The equipment of the oil depot is controlled by a computer. The signal of the mobile phone will affect the normal operation of the equipment, resulting in inaccurate measurement. More importantly, the mobile phone will spark during the dialing process, which can easily cause a fire and cause the oil depot to explode. Faraday Cage To Block Cell Phone Signal After startup, it can continuously transmit interference signals for all mobile phones on the market (including 2G, 3G, 4G, telecom, China Unicom, and all frequency bands of China Mobile) and 2.4G and 5G Wi-Fi and Bluetooth devices. cell phone jammer All mobile phones, wireless local area network Wi-Fi and Bluetooth devices within the shielding range will lose communication functions, unable to send and receive text messages, make calls or browse the Internet.
Oil Depot Faraday Cage To Block Cell Phone Signal Product features: The oil depot mobile phone signal jammer effectively shields the 2G+3G+4G mobile phone frequency band + WIFI wireless network mobile phone signal jammer; the new aluminum alloy oxide shell with high heat dissipation performance is used, and the equipment has good long-term working stability; the use of foreign advanced chips and technology, slow-start circuit design, high integration; using ultra-high frequency broadband interference technology, only interferes with the downlink, not the base station; using multi-channel segmented independent shielding 3G/4G technology, the shielding effect is better; single-machine transmit power 25W, Each channel is about 2W-5W; the effective shielding range is 0-50 meters (depending on the operator's network signal conditions); it can continue to work without downtime all year round;
