5G mobile phone jammer

When customers ask us about the product functions and technical specifications of the shielding equipment, they sometimes make such a clear request: can the shielding distance of the 5G mobile phone jammer they want to purchase be accurately controlled at a position of 5 meters or 10 meters? Because customers are very strict on the distance control of the use site, they don't want the shielding distance to be too large, and they don't want the shielding distance to fall short of the required coverage. So, can such a requirement be met?

We have to understand the customer's on-site situation in detail before we can make an analysis and answer. If the customer installs the 5G mobile phone jammer in a relatively isolated indoor space, there is a solid reinforced concrete wall at a distance of 5 meters or 10 meters from the installation position of the 5G mobile phone jammer. During the transmission process, when encountering a wall, part of the signal will be refracted or reflected, and part of the signal will penetrate the wall, but this penetration process will be greatly attenuated, passing through the wall The strength of the shielding signal will be greatly weakened, and the ability to shield the mobile phone signal has not been reached. This means that if there is isolation or blocking by the wall, the signal attenuation effect of the wall can be used to basically achieve accurate shielding. transmission distance. However, it should be noted that only a completely solid reinforced concrete wall can have a greater attenuation effect on the shielding signal. If it is replaced by a gypsum board partition wall, a wooden partition wall or a glass partition wall, then the wall is used as the control 5G mobile phone The shielding distance approach for jammers will no longer be feasible.

If the usage scenario required by the customer is another form: the 5G mobile phone jammer is installed in a relatively open or very large indoor space, and there are no obstacles within tens of meters around it. In this scenario, It is still required that the shielding distance be accurately controlled at a position of 5 meters or 10 meters. To tell the truth: such a requirement is basically impossible to achieve in the field of radio frequency signals.

The actual effective shielding distance of the shielding signals of various standards emitted by the 5G mobile phone jammer is not exactly the same, it depends on the strength of the mobile phone signal at the scene, or depends on the surrounding mobile phone base stations of various standards distance. Moreover, in the process of the shielding signal diverging and transmitting in the air, the signal strength value is a process of gradually attenuating and weakening. In the case of obstacles, it is impossible to achieve a one-size-fits-all effect, and it is impossible to accurately control the shielding signal. At a certain specified distance, the signal suddenly disappears or is cut off.
