How to test the shielding distance of high-power signal jammer?
The effective shielding range of high-power signal jammer will be different in different use sites. This is closely related to the on-site signal field strength, that is, the distance of the on-site base station. The shielding range of different mobile phones at the same site is not necessarily the same.
When selecting the test site for high-power jammers, we should look at the distance between the surrounding base stations and the test site. We generally require that the base stations be 300 meters away from the test site, and there are barriers in the middle, so the test effect is relatively ideal.
After the test site is selected, the high-power signal jammer will be erected. If it is not fixed, the jammer shall be erected on the desktop; There are arrows on the back of the machine. For fixed wall mounting, the installation height of high-power signal jammer is required to be within 3-5 meters. The high-power signal jammer has been debugged and aged before leaving the factory. It can work after being powered on directly without any debugging.
After the high-power signal jammer is turned on, prepare all standard mobile phones and keep away from the high-power signal jammer in a straight line along the front of the antenna. Set the positions of 20-50-100-150-200 meters respectively to ensure that there is no obstruction in the middle. Try to keep the mobile phone at the same height as the shoulder. After staying at each point for 2 minutes, check whether the mobile phone has a signal, and try to call and surf the Internet. If it cannot be connected, move to the next point for the same operation. Until the point where the call can be made, the point cannot be shielded.
