The full-band jammer only shields 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 overlap with the mobile phone frequency band, so the full-band jammer will not interfere other wireless signals. For example, wireless microphones generally use a frequency band of 700MHz, while the lowest frequency band of full-band signal blocker is 865-885MHz of China Telecom. The two are not in the same frequency band, so they will not interfere. However, during use, the distance between the wireless microphone and the full-band jammer must be kept more than 1-2 meters to prevent electromagnetic wave interference.
In life, we are more common radios, walkie-talkies and so on. In all frequency band jammers, specific frequency bands can be customized for jamming. As for the Wi-Fi signal, our full-band jammer is jammed when it leaves the factory. This is to prevent the phone from getting in touch with the outside world by connecting to the WiFi network.
