Mobile phone signal shielding device mainly used in the situations that need to prohibit the use of mobile phone, such as examination room, school, and church, etc.

Mobile phone signal shielding device can also be called as shielding device, mobile phone shielding device, signal shielding device, mobile phone signal jammers, mobile phone signal blocking device, mobile communication signal shielding device, mobile phone signal shielding device, mobile phone jammers, mobile phone signal jammers, blocking device, signal blocking device, signal isolator, etc.

 

 

It aims at the downlink channel of the mobile phone system. it uses frequency doubling, frequency division and frequency hopping filtering to analyze shielding needs. According to the size of the shielding power, a spherical shielding space is designed, and a shielded magnetic field is automatically formed in a given range so that the mobile phone in the space is invalid. When the shielding device is in the working state, the mobile telephone receiving and sending signal function in the designated range can be invalid and cannot be dialed out or dialed in to achieve mandatory prohibition.

 

Mobile phone signal shielding device principle: in a certain frequency range, The mobile phone and the base station are connected by radio waves to transmit data and sound with a certain baud rate and modulation. In the work process, mobile phone signal shielding device scans from low frequency of the channel to the high-end at a certain speed. The scanning speed can form garbled interference in the receiving message signal of the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is characterized by search network, no signal, no service system and so on.

 

As tungsten has high density and high atomic number, and high density is closely related to radiation density, mechanical properties, and strength, it can be used as components of mobile phone shielding device, which can better play its shielding effect.
