many people would like to buy bluetooth jammer

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

Signal jammer is mainly aimed at various examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, military places and other places where the use of mobile phones is prohibited. It is understood that cell phone signal blockers on the market can limit cell phone signals to 500 meters away from the launching station. The shielding radius is adjustable, and the coverage area reaches more than 30 square meters.The mobile phone signal shielding device can only shield mobile phone signals and does not affect other electronic equipment.

During operation, the shield scans from the low end to the high end of the forward channel at a certain speed. The scanning speed will cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, causing the mobile phone to fail to establish a connection with the base station.Mobile phones appear to search the network, no signal, no service system, etc.Select the area where the mobile phone signal needs to be cut off, and place the cutter on the desk or wall in that area.
