The superposition of the number of 5G jammers cannot represent the superposition of mobile phone interference effects

5G jammer


A customer installed a 5G jammer in a large conference room environment. The feedback result is that the effect of mobile phone interference is indeed there, but because the conference room area is too large, if only one 5G jammer is installed, Certainly cannot achieve complete coverage of mobile phone interference signals. Customer question: Can a 5G jammer be installed in the same installation location. After doing so, is the transmission power of mobile phone jamming doubled? Can the interference effect for mobile phone interference also be doubled?
Our answer is no. Adding the same 5G jammer in the same installation location will not double the transmit power and jamming effect. The real result is almost no change. The reason is that the signals emitted by the 5G jammer for mobile phone interference in various frequency bands are essentially radio frequency wireless signals. The transmission and attenuation process of the wireless signal is indeed related to the signal transmission source (here, the 5G jammer). The power is related, but at the same transmission source, only by increasing the number of signal transmission sources with the same power, the signal transmission and error are still the same, and there is no improvement.
An analogy can be made here: the propagation properties of sound and wireless signals are similar. When a person stands somewhere with a normal speaking volume, the distance of sound propagation is assumed to be 30 meters, and then we increase the number of people speaking at the same position. When there are 2 or more, these people are required to speak with the same volume of voice. Obviously, the sound of these people will only travel at a distance of about 30 meters, and there will be no increase in the distance.
Then, in the face of the customer's problem, in a large conference room, what method should be taken to improve the effect of mobile phone interference?
There are two solutions: one is to replace the 5G jammer with a larger transmit power. The second is to increase the number of 5G jammers of the original model, but it should be noted that the increased mobile phone jamming devices cannot be installed in the same location, but the cellular networking method is adopted, which is the correct solution. .
