Why can the high-power jammer block the mobile phone signal?
Why use a high power jammer? How does a high-power jammer interfere with mobile Internet access? Many users do not understand the working principle of high-power signal blocker, because the frequency range of ordinary jammers often does not reach the ideal state, resulting in poor actual use effect, so switching to high-power jammers can shield wider . General communication equipment works in the same signal frequency range. For example: when a mobile phone surfs the Internet, the mobile phone and the base station mainly transmit each other through wireless signal technology, and transmit in a specific signal frequency, so that the mobile phone can realize communication with the outside world, Internet access and other functions.
According to the above working principle, a section of signal frequency generated by the high-power jammer will cover the signal frequency used by communication equipment. In this way, the signal data sent by the base station cannot be received by the mobile phone, so that the base station cannot establish contact with the mobile phone, so that the mobile phone cannot be connected to the base station communication network. The mobile phone shows that there is no signal and no service system in the search network, so as to achieve the effect of interference blocking. The shielding effect of the high-power jammer will not be certain, first of all, the effect is also circular and gradual with the high-power jammer as the center and working outside. In order to realize the successful interference of the high-power jammer on the mobile phone network, it must be ensured that the signal field emitted by the high-power jammer is stronger than the interfered target. Within a certain power, the interference range depends on the strength of the magnetic field signal in the interference area.
