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, and the signal strength of the white noise interference signal of the same frequency of the mobile phone signal transmitted by the mobile phone jammer is not the same. changing. So let the white noise interference signal with the same signal strength emitted by the mobile phone shielding device to shield the mobile phone signal of different frequencies to the mobile phone signal with different signal strength at the use site, and the shielding distance of the mobile phone 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 mobile phone GPS jammer, and vice versa. The mobile phone signal is too strong, so that the mobile phone is placed next to the mobile phone shielding device, and the mobile phone can still be used normally without any influence. This situation is also relatively common. In this case, conventional cell phone jammers cannot be used.

After the on-site test, if the mobile phone shielding device does not have good shielding effect on the mobile phones of some operators, it can basically be judged that the strong signal strength of the mobile phone on the site leads to the poor shielding effect. How to solve this situation? Welcome to consult the mobile phone signal shielding professional company-topsignaljammer Technology Co., Ltd., we will give you the most optimized design plan and provide free technical consultation. Mobile phone signal jammer, can it be shielded through the wall through the wall? To answer this question, several situations need to be considered.
First of all, look at the mobile phone signal jammer itself. The mobile phone wifi jammer emits a radio frequency signal specially designed for mobile phone signals. When it encounters the wall in the transmission path, some of the signals will be reflected back, and some of the signals can directly penetrate the wall. But the signal strength will be attenuated to a certain extent. And facing different walls, the attenuation degree of mobile phone jammers is also different. For example, the wall is a reinforced concrete wall or a brick-concrete wall. One wall of reinforced concrete and two continuous walls of brick and concrete, then the interference signal emitted by the mobile phone signal jammer will basically be attenuated, that is to say, it cannot be used through the wall. Therefore, the signal emitted by the mobile phone signal jammer usually cannot pass through the wall. After all, the shielded signal (wireless signal) is not X-ray, and it does not have the ability to penetrate directly, and there will be certain refraction and reflection when it encounters the wall.
Signal Jammer For SaleDifferent wall materials have different degrees of attenuation to the mobile phone jammer. For example, if the wall is made of light steel keel gypsum board, its attenuation will be small, and like glass, wooden doors, etc., the attenuation is also small. In addition, if the signal of the mobile phone jammer will also be refracted through the open space of doors and windows or through the reflection and refraction of the wall, it will have some influence on the mobile phone signal behind the wall, so that people feel that the mobile phone signal jammer has the ability to penetrate The illusion of penetration.
Of course, the size of the wall penetration ability is also related to the transmit power of each frequency band of the mobile phone jammer. Generally speaking, the larger the transmitting power, the stronger the penetrating ability. It is the same as listening to the sound of the next door through a wall. If the sound of the next door is louder, you can hear it clearly. won't hear it.
