Some people said that a wireless mobile jammer with a shielding radius of 50 meters and an interval of 500 meters is needed, which should be shielded by the three networks of China Mobile, China Unicom and Telecom, and also gave specific shielding distance requirements. In fact, this is not the case, because the shielding distance of wireless mobile jammer is not a fixed value. Let's take you to know.

In the working process, the wireless mobile jammer scans from the low-end frequency to the high-end frequency at a certain speed. This scanning speed can cause garbled interference in the received signal of the mobile phone, so that the mobile phone cannot detect the normal signal data sent by the base station, so that the mobile phone cannot establish a connection with the base station in a certain area, so as to achieve the purpose of shielding the mobile phone signal.

In short, the transmission power of the wireless mobile jammer is lower than the power sent by the base station to the mobile phone, so the interference effect of the wireless mobile jammer will be greatly weakened and can't be shielded basically. However, as long as the power of the wireless mobile jammer is greater than the power sent by the base station, it can be effectively shielded. Therefore, if any wireless mobile jammer is used in different field environments, it will show different shielding distances, that is, how many meters a wireless mobile jammer can shield depends not only on its own transmission power, but also on the density, orientation and power of base stations built by three nearby operators.
