The cell phone jammer is mainly aimed at various places where the use of cell phones is prohibited, such as examination rooms, schools, gas stations, churches, courts, libraries, conference centers, theaters, hospitals, governments, finance, prisons, public security and military powerhouses.
When the cell phone works, the mobile phone and the base station are connected by radio waves within a certain frequency range, and the data and sound transmission are completed with a certain baud rate and modulation method.
In response to the communication principle, cell phone signal interference scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. The cell phone is manifested as a search network, no signal, no service system and other phenomena.
The cell phone jammer is green and environmentally friendly. The amount of electromagnetic radiation has been tested strictly. The electromagnetic field strength at each sampling point has no impact on the human.
The cell phone jammer has low power and built-in switching power supply to ensure the stability and accuracy of the signal.
The cell phone jammer is easy to operate, install the antenna correctly, and it can run automatically after power on.
