How does the wireless jammer shield the mobile phone signal?

  • 2023-01-01

The main function of wireless jammer is to shield the signal of mobile phone communication equipment. At present, it is mainly used in meeting rooms, schools and detention centers, which can be said to be widely used. If you now have a mobile phone through communication software and network, the information sent can be spread to any corner of the world instantly, and the speed of information transmission is so fast. However, compared with the above places, sometimes it does not need a mobile phone, and there is no motivation to use it. In this case, shielding devices can be used. The wireless jammer shields and interferes with the signals received by the mobile phone according to the communication principle of the mobile phone, so as to shield the mobile phone signals.

Now, as one of the most important communication devices, mobile phones can also receive signals from nearby base stations before sending information to the outside world, so that the opposite party can transmit its own signals. The information is mainly transmitted by the electromagnetic wave, and the wireless signal frequency band used by the mobile phone is closely related to each operator. The current signal shielding devices are all full band interference devices, which can effectively shield all bands of the three major operators when working. When the wireless jammer is working, it scans from the low frequency band to the high frequency band at a certain speed of the waveform, and generates multiple wireless signals to cover the operators' signals in each frequency band, finally forming a shielding area, so as to achieve the desired effect.
