It is understood that the cell phone signal jammers on the market can limit cell phone signals beyond 500M meters from the transmitter. The radius of the signal shielding can be adjusted independently, and the coverage is more than 30 square meters. The power of the mobile phone signal shielding device is generally 12W--480W.

Can cell phone signal blockers block wifi signals?

The high-power mobile phone signal blocker can not only block mobile phone signals, but also effectively block WiFi signals, GPS signals, and Beidou satellite signals. Among them, because the working frequency of WiFi and WLAN signals is in the range of 2.4GHZ or 5.8GHZ, if you need to block WiFi signals, it is recommended that you buy a high-power "topsignaljammer" mobile phone signal jammer.

The cell phone jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal 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. The mobile phone is manifested as searching the network, no signal on the mobile phone, no service system, etc.

Portable cell phone signal blocker adopts imported IC and is independently developed, especially for some small places at home and abroad that require security and confidentiality, such as confidential offices, negotiation rooms, mobile vehicles, mobile political and business dignitaries to guard the scene, etc. , a high-tech product carefully developed according to the actual situation of mobile communications at home and abroad, 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). (The enhancement can block WiFi signals, GPS signals, and Beidou satellite signals), so that mobile phones in the area cannot make and receive calls, and will not interfere with the work of other electronic devices in the environment. When the mobile phone is far away from the shielding range, it can resume normal use.
