How much is the mobile phone signal shielding device _ mobile phone signal shielding device price know
Cell phone signal shielding devices are mainly used in various test rooms, schools, gas stations, churches, courts, libraries, conference centers (rooms), theaters, hospitals, government, finance, prisons, public security, military heavy places and other places where mobile phones are prohibited. It is understood that the mobile phone signal shielding device on the market can now limit the mobile phone signal of the range of 20 meters from the launching station, such as the range radius of the shield of the P501 of Jin Yuda. The shielding radius is adjustable, and the coverage is up to 30m2. The mobile phone signal shielding device can only shield the mobile phone signal without affecting other electronic devices. Save energy, power is 12W--480W.
The mobile phone shield scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. The scanning speed can form garbled interference in the message received by 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. Mobile phones are characterized by search networks, no signal on mobile phones, and no service systems.
