The mini signal jammer is the perfect tool to block the frequency signal from the base station. Turn on the jammer and no one can contact you. Your caller will receive an automatic message informing you that your number is out of coverage. When you put the cell phone jammer into use, all nearby cell phones will be disabled within 2-5 seconds, and its owner will not be able to make and receive calls, send text messages and receive messages.
The mini cell phone jammer has many advantages: First, it is portable and easy to operate, which is why you can take it with you. In addition, this jammer can be charged while being very convenient to use. In addition, this mini mobile phone jammer can facilitate the driver to block incoming calls, thereby distracting while driving. In addition, with this electronic device, passengers will enjoy silent travel. By the way, if you want to prevent the leakage of important information, then you need to carry a mini cell phone jammer with you.
The 4G wireless signal jammer is generally composed of a power supply, an electronic scanning control unit, a segmented radio frequency module unit, an amplifier unit, and a transmitting antenna unit. The scanning signal generated by the signal generator passes through the inverter, enters the oscillator and modulates it to the mobile communication working frequency band, and then is amplified by the power amplifier and the voltage regulator tube controls the power. The amplified frequency sweep signal is transmitted into the air in the form of radio waves.
The wireless wifi jammer causes garbled interference in the message signal received by the mobile phone due to the frequency sweep signal (increase the ratio of the noise signal to the device threshold), the mobile phone cannot receive the normal 4G data sent by the base station, so that the mobile phone cannot establish a normal connection with the base station , So that the mobile phone is separated from the base station communication network. The mobile phone shows the phenomenon of no signal and no service system in the search network, which achieves the blocking effect.
