Many people want to buy a bluetooth jammer

wifi signal jammer

Some simpler devices can only block one set of frequencies, while advanced cell phone jammers can block multiple types of networks at the same time, cutting off dual-mode or triple-mode cell phones, making it impossible to switch between different networks and find an open signal. Some high-end Bluetooth jammers can block all frequencies at once, while others can be set to block specific frequencies. To jam a cell phone signal, all you need is a device that can broadcast on the correct frequency. While different cellular systems handle the signal differently, the radio signals used by mobile phone networks can be blocked.

Signal jammers are mainly used in various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military sites and other places where the use of mobile phones is prohibited. The shielding radius is adjustable, and the coverage area reaches more than 30 square meters. The cell phone signal blocker can only block cell phone signals and does not affect other electronic devices.

During the mission, the shield scans from the low end to the high end of the forward channel at a certain speed. If the scanning speed is too fast, the SMS signal received by the mobile phone will appear garbled, and the mobile phone cannot detect the normal data sent by the base station, The mobile phone appears to search the network, no signal, no labor system and so on. Select the area where you need to cut off the cell phone signal and place the cutter on a table or wall in that area.
