Is the mobile phone signal jammer interfering with other wireless signals?

  • 2022-05-17
We all know that in some special situations, mobile phone signal jammers are required to interfere with mobile phone signals to prevent disclosure or cheating. For example, mobile phones are not allowed to be carried in some secret related meetings. Mobile phone signals will be interfered by jammers in the venue.

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

Simply put, take the mobile phone as an example. The mobile phone needs to communicate with other devices outside the examination room through the signal tower, while the wireless communication needs to be carried by electromagnetic wave. According to the characteristics of electromagnetic wave, the devices on both sides need to be sent and received within a certain frequency range. The signal jammer is to affect the frequency of your electronic equipment and make the frequencies of both sides different, so as to achieve the effect of interference.

Wireless microphones are usually used in classified meeting rooms. Will the wireless microphones or other wireless devices be affected after the signal jammer is turned on?

The Signal Jammer only interferes with the 2G / 3G / 4G / 5G signal of the mobile phone, and the output frequency band is the fixed frequency band used by the mobile phone, while the frequency band used by other wireless signals will not coincide with the frequency band of the mobile phone, so the mobile phone signal jammer will not interfere with other wireless signals. For example, wireless microphones generally use the frequency band of 700MHz, while the lowest frequency band in the signal jammer is 865-885mhz of Telecom. They are not in the same frequency band, so they will not interfere. However, during use, the distance between the wireless microphone and the Signal Jammer shall be kept more than 1-2m to prevent electromagnetic wave interference.

In life, we are more common radios, walkie talkies and so on. In the mobile phone signal jammer, you can customize a specific frequency band to interfere. Wi Fi signals and our signal jammers are interfered when they leave the factory. This is to prevent the mobile phone from contacting the outside world by connecting to the WiFi network.
