Why are there wireless jammers?

  • 2022-05-22

Wireless jammer mainly shields the signal of mobile communication equipment. At present, it is widely used in conference rooms, schools and detention centers. Now, with a mobile phone, through communication software and network, the information sent can be transmitted to any corner of the world in an instant. The transmission speed of information is so fast. However, compared with the above places, it sometimes does not need mobile phones. At this time, it can use shielded devices. According to the communication principle of the mobile phone, the wireless jammer interferes with the signal received by the mobile phone to achieve the purpose of shielding the mobile phone signal.

As one of the most important communication devices, mobile phones can also receive the signals sent by nearby base stations before sending information to the outside world, so that the opposite party can transmit its own signals. Information mainly depends on the carrying of electromagnetic waves, and the wireless signal frequency band used by mobile phones is closely related to various operators. At present, the signal shielding equipment interferes with all frequency bands. It can effectively shield all frequency bands of the three operators when working. When the wireless jammer works, 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 signals of each frequency band of the operator, and finally form a shielding area to achieve the desired effect.
