There are some customers who buy their favorite mobile phone
jammer with great joy, but they find that the signal shielding effect is very poor when using it, and they can even make calls normally while standing next to the shielding device. What's going on? It turned out that after the analysis and inspection of the site, the customer found that it was the mobile phone jammer that encountered the indoor signal amplifier during signal interference.
The indoor signal amplifier we are referring to is mainly installed in the corridors of multi-story buildings, especially high-rise buildings with more than ten floors, or in areas such as elevator shafts and underground car inventory, because these places receive The signal from the surrounding mobile phone base stations will be relatively weak, or even completely unable to receive the signal of the base station, so the indoor signal amplifier is installed to make these weak signal areas obtain sufficient strength of the mobile phone signal. The problem is that the purpose of using the mobile phone jammer is to interfere with the signal. As a result, when the signal amplifier is encountered, the signal shielding effect is not good. This is the inevitable result.
So, in the case of a signal amplifier, I still want the mobile phone jammer to interfere with the signal normally, what can be done? There are still ways. Because indoor signal amplifiers are usually composed of a host and multiple indoor antennas. The best way to solve the problem is to find the nearest indoor antennas that need to interfere with the signal, and remove these antenna terminals or cut off the RF output. After being implemented in this way, the signal strength of mobile phones in these places can be reduced to some extent, and at the same time, the effective shielding distance of the shielding signal emitted by the mobile phone jammer can be significantly improved.
