When testing the shielding effect of the full-band signal shielding instrument on the site, it is often encountered that the shielding instrument shows different shielding effects on mobile phones of different operators, and some are even very different. This situation is often encountered in the process of testing or use, so what is the reason for such a situation, and how to deal with such a situation?

The reason why this happens in the first place is because the signal strength of mobile phone signals of different frequencies transmitted through the base station to the site of use is different, while the signal strength of the white noise interference signal with the same frequency of the mobile phone signal transmitted by the full-band signal shielding device is constant. Therefore, the white noise interference signal with the same signal strength emitted by the shielding device is used to shield the mobile phone signals of different frequencies to the mobile phone signals with different signal strengths at the use site, and the shielding distance of mobile phones of different operators is different. Using the shielding scheme of white noise interference mode, the shielding effect depends on the strength of the mobile phone signal at the site. It can also be understood as the distance of the surrounding operator base stations. The stronger the signal at the scene, the closer the shielding distance of the full-band signal shielding device, and vice versa. The mobile phone signal is too strong, so that the mobile phone is placed next to the shielding device, and the mobile phone can still be used normally without any influence. This situation is also relatively common. In this case, the conventional shielding device cannot be used.

After the on-site test, if the full-band signal shielding device has poor shielding effect on some operators' mobile phones, it can basically be judged that the strong signal strength of the mobile phone on site leads to the poor shielding effect.
