Mobile phone signal jammer solution for oil depot

　　When the mobile phone battery starts, when the bell rings, it can generate enough energy to cause a slight spark, which may cause a fire. Petroleum, chemical, security and other relevant departments have clearly stipulated that oil depots prohibit the use of mobile phones. It has been a long time since the introduction, but the current implementation is not ideal. The equipment in the oil depot is controlled by a computer. The signal of the mobile phone will affect the normal operation of the equipment and cause inaccurate measurement. More importantly, sparks will appear during the call from the mobile phone, which can easily cause a fire and cause an explosion in the oil depot.

　　After the oil depot mobile phone signal jammer is activated, it will continuously transmit interference signals against all mobile phones on the market (including all frequency bands of 2G, 3G, 4G, telecommunications, China Unicom, and China Mobile) and 2.4G and 5G Wi-Fi and Bluetooth devices , All mobile phones, wireless LAN Wi-Fi and Bluetooth devices within the shielding range will lose their communication functions and cannot send and receive text messages, make calls or browse the Internet.
