There are many different names for mobile phone signal jammers, jammer, Wifi Bluetooth Cell Phone Jammer , signal jammer, mobile phone signal jammer, mobile phone signal blocker, mobile phone isolator, mobile phone interceptor, mobile communication signal jammer, mobile phone signal degree shielding Instrument, mobile phone jammer, signal jammer, mobile phone blocker, signal blocker, mobile phone signal isolator, signal isolator, mobile phone signal interceptor, radio signal jammer. For the uplink and downlink channels of the mobile phone system, it uses techniques such as frequency multiplication, frequency division, and frequency hopping filtering to analyze the required shielding frequency; customize a spherical shielding space according to the power of the mobile phone jammer, and automatically form shielding within the specified range The magnetic field makes the mobile phones of mobile phones (including PHS-PHS-GSM-China Unicom, China Mobile, CDMA-China Telecom) ineffective in this space. When the mobile phone jammer is in the working state, it can make the mobile phone's signal receiving and sending function in the specified range invalid, unable to dial out and dial in, so as to achieve the purpose of compulsory prohibition. cell phone jammer
When the battery of the mobile phone is started, when the bell rings, the electric spark that can generate enough energy to cause a slight spark may cause a fire. In the safety-related part, there is an express provision that gas stations should prohibit the use of mobile phones. It has been a long time since the introduction, but the status of implementation is not ideal now. The equipment at the gas station is controlled by a computer. The signal from the mobile phone will affect the normal operation of the equipment and cause the metering to be prohibited. More importantly, the mobile phone will show sparks during the dialing process, which can easily lead to fire and cause the gas station to burst. Adding Wifi Bluetooth Cell Phone Jammer at the gas station can prevent some tragedies from happening. Therefore, gas stations that are classified as fire-resistant sites not only prohibit the use of mobile phones in the station, but also do not use mobile phones within two or three meters around the gas station. At the same time, gas stations should set up prominent symbols to stop calling mobile phones, and widely promote safety common sense,
