The Signal Jammer realizes the interference and interference to the wireless communication signal by transmitting the same frequency interference signal, so that the mobile phone can form garbled interference in the received message signal. The mobile phone can not detect the normal data sent from the base station, so that the mobile phone can not establish a connection with the base station. The quality of components and debugging technical parameters used in the transmission power frequency range of the jammer directly affect the effect of the interference signal. This will involve the frequency band and transmission power of wireless communication signals. In order to achieve signal interference, it is necessary to transmit strong enough signal interference in the same frequency band, otherwise the interference effect cannot be guaranteed.

Signal Jammer has been used for many years. Theoretically speaking, it is a mature technology. Why can't it interfere with 5g signal now? If the signal jammer is placed and installed normally or cannot interfere with the mobile phone signal, it may be the interference of the nearby communication base station. If the jammer is used in a place close to the communication base station, there will be intermittent interference problems. In some cases, signal amplifiers are installed. In order to improve communication quality, mobile phone signal intensifiers will be installed in some cases, which will directly affect the use effect of jammers.
