if you wanna know what are jammers used for

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.The cell phone 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. Today, Saiyue Communication will tell you the applicable scope of mobile phone jammer.

With the rapid development of mobile communication networks, network coverage is constantly expanding. Wireless communication relies on the propagation of electromagnetic waves to establish communication links.Then customize a spherical shielding space according to the power of the shielding device, and automatically form a shielding magnetic field 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 the working state, it can disable the signal receiving and sending functions of the mobile phone within the specified range, and cannot dial out and dial in, so as to achieve the purpose of mandatory prohibition.Maybe you know What Are Jammers Used For.

The mobile phone shielding device has a wide range of applications, and 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.
