Mobile phone signal blockers are mainly used in various examination venues, schools, gas stations, churches, courts, libraries, conference centers (rooms), cinemas, hospitals, government departments, financial institutions, prisons, public security agencies, defense key areas and other places where mobile phones are strictly prohibited. According to statistics, the cell phone signal blockers on the market today can block mobile phone signals 500 meters away from the tower. The signal blocking radius can be adjusted automatically, and the coverage area can reach more than 30 square meters. The output power of the cell phone signal blocker is generally 12W--480W.

Can cell phone signal blockers block Wi-Fi numbers?

High-power cell phone signal blockers can not only block mobile phone signals, but also effectively block Wi-Fi signals, GPS signals, and Beidou satellite signals. Among them, since the output power of Wi-Fi and WLAN signals is in the range of 2.4GHZ or 5.8GHZ, if you need to block Wi-Fi signals, it is recommended that you purchase the high-power "Texin Electronics" SYT-G2100 portable 8-way mobile phone signal blocker.

The mobile phone blocker scans the low-power to high-power wireless channels at a certain speed during operation. This scanning speed may cause error code effects in the mobile phone receiving message format data signals, and the mobile phone cannot detect the normal data sent from the communication base station, making it impossible for the mobile phone to establish a connection with the communication base station. The mobile phone mainly manifests itself as searching for the network, poor mobile phone signal, no service system, etc.

The portable mobile phone signal blocker is a high-tech product developed by ourselves using imported IC, especially for some small places in various countries that need special security and confidentiality, such as customs offices, reception halls, mobile vehicles, mobile political and business dignitaries protection sites, etc. It can block GSM/CDMA/DCS/PHS/PCS/3G mobile phone signals within a radius of 0.5-15 meters (usually about 5-80 square meters) (it can block Wi-Fi signals, GPS signals, Beidou satellite signals), making it impossible for mobile phones in the area to be sent out and connected, and it will not affect the work of other electronic products in the environment. When the mobile phone is out of the shielding range, it can be restored and used.
