Does the wireless jammer interfere with other wireless signals?

  • 2022-08-18
As we all know, in some special situations, wireless jammers are required to interfere with mobile phone signals to prevent secret disclosure or cheating. For example, mobile phones are not allowed to be carried in some secret related meetings, and there are no mobile phones. Mobile phone signals will be interfered by jammers in the venue.

So how does the wireless jammer interfere with the mobile phone?

To put it simply, take mobile phones as an example. Mobile phones need to communicate with other devices outside the examination room through the signal tower, while wireless communication needs electromagnetic waves to carry. According to the characteristics of electromagnetic waves, the devices on both sides need to be within a certain frequency range to send and receive. Therefore, the wireless jammer is to affect the frequency of your electronic devices to make the frequencies of both sides different, so as to achieve the effect of interference.

Usually, wireless microphones are used in classified conference rooms. Will the wireless microphones or other wireless devices be affected after the jammer is turned on?

The wireless jammer only interferes with the 2G / 3G / 4G / 5G signals of the mobile phone. The output frequency band is the fixed frequency band used by the mobile phone, and the frequency band used by other wireless signals will not overlap with the frequency band of the mobile phone. Therefore, the jammer will not interfere with other wireless signals. For example, wireless microphones generally use the frequency band of 700MHz, while the lowest frequency band of wireless jammers is 865-885mhz of telecommunications. The two are not in the same frequency band, so they will not interfere. However, in the process of use, the wireless microphone shall be kept at a distance of more than 1-2 meters from the jammer to prevent electromagnetic wave interference.

In our life, we are familiar with radios and walkie talkies. In wireless jammers, interference can be carried out by customizing specific frequency bands. While Wi Fi signals, our jammers are jammed when they leave the factory. This is to prevent the mobile phone from connecting with the outside world through the WiFi network.
