Mobile phone signal jammers are generally directly called jammers, mobile phone jammers, signal jammers, mobile phone signal jammers, mobile phone signal blockers, mobile phone isolators, mobile phone interceptors, etc. There are also mobile communication signal jammers, mobile phone signal jammers, mobile phone jammers, signal jammers, mobile phone blockers, signal blockers, mobile phone signal isolators, signal isolators, mobile phone signal interceptors, and radio signals according to their functions. Shields, etc.
The mobile phone signal jammer adopts techniques such as frequency multiplication, frequency division, and frequency hopping filtering for the upstream and downstream channels of the mobile phone system to analyze the required shielding frequency. Then a spherical shielding space is customized according to the power of the shielding device, and a shielding magnetic field is automatically formed within the specified range, so that the mobile phone signal of the mobile phone in this spherical shielding space is invalid. When the mobile phone jammer is in working condition, it can disable the signal receiving and sending function of the mobile phone within the specified range, and cannot dial out and dial in, so as to achieve the purpose of compulsory prohibition.
The mobile phone shielding device has a wide range of applications, and it can be used in many occasions or areas, such as various invigilators, prisons, detention centers, drug rehabilitation centers, offices, conference rooms, gas stations, oil depots, churches, hospitals, courts, and military centers. , Libraries, theaters, factory workshops and other places.
However, it should be noted that in densely populated areas such as schools, it is forbidden to set up radio stations with excessive electromagnetic radiation, and mobile phone signal jammers are not allowed to be used in residential areas.
Cell phone jammer can shield 2/3/4/5G signals, GPS, WiFi, drones and other signals. They are mainly used in prisons, schools, churches, gas stations and other places to provide you with shielded communication services to protect your privacy Safety!
