Nowadays, in people's life, everyone carries a mobile phone with them. Every day, people use their mobile phones to make calls and send messages. In some relatively secret offices and conference rooms, in order to prevent information leakage, is there any good way to make their mobile phones unable to communicate? Of course, Jammer Modules can avoid this problem.
What are the uses of Jammer Modules?
How can weuse the Jammer Modules?
How do Jammer Modules work?
Jammer Modules are mainly used in various exam rooms, schools, gas stations, conference centers, hospitals, prisons and other places where the use of mobile phones is prohibited. The signal interference radius can be adjusted and the coverage area is large. When using a wireless signal jammer device, in order to avoid the possible interference of the wireless signal jammer to some electronic devices, the following common devices should be kept as far away as possible: stereos, wireless microphones, radios, computers, TVs, Wi-Fi routers, etc. Choose a high-power machine or a low-power machine according to your needs. It can effectively interfere with all 2G, 3G, 4G, 5G and WIFI signals of China Mobile, China Unicom and China Telecom.
Select the area that needs to interfere with the cell phone signal, and place the Jammer Modules on the desktop or on the wall in that area.
After installing and connecting the device, turn on the power switch of the Jammer Modules. Press the power switch to work. At this time, all mobile phones on the scene are in the state of searching for the network, and the signal connection with the base station is interrupted.
We need to know what Jammer Modules are for. When you use a wireless signal jammer, you can follow the above method.
The principle is that the positioning remote control is mainly composed of a microprocessor chip that forms a remote control signal, a crystal oscillator, an amplifier transistor, an infrared light-emitting diode and a matrix. The working principle of Jammer Modules is as follows. The oscillator inside the microprocessor chip IC1 forms a high-frequency oscillator through pins 2 and 3 and an external oscillating crystal X to generate a high-frequency oscillating signal. The sine signal and timing pulse signal generated after this signal is sent to the timing signal generator. The sine signal is sent to the code modulator as the carrier signal; the timing pulse signal is sent to the sweep signal generator, the keyed input encoder and the command encoder as the time standard signal of these circuits. The encoding circuit encodes the key information into a pulse signal. Different keys have different pulses after encoding. The pulse signal is over-amplified to drive the infrared light-emitting diode to emit pulsed infrared light.
