The on-site signal is too strong, how to improve the interference effect of the mobile phone signal jammer?

In modern society, mobile phones have become an indispensable part of people's lives. However, in some occasions, such as conference rooms, examination rooms, movie theaters, etc., the ringtones and calls of mobile phones can seriously disturb people around them and affect their normal work and life. In order to solve this problem, a full-band jammer came into being. However, in the process of using the mobile phone signal jammer, sometimes it is found that the mobile phone signal is strong, resulting in poor shielding effect of the jammer. So, how to improve the shielding effect of the mobile phone signal jammer?

First, we can consider increasing the number of shields. By using multiple interferometers together, the requirement of covering the entire meeting room can be achieved. Although this method can improve the coverage of the jammer, it requires more investment and is not very practical.

Secondly, we can know the frequency band with the strongest mobile phone signal on site through the spectrum analyzer test or the mobile phone signal detection software Cellular-Z. According to the frequency parameters tested, a high-power shielding module for this frequency band can be made to specifically shield the frequency band with strong mobile phone signals, so as to achieve the effect of the mobile phone signal jammer to shield these signals. This method can solve the problem of strong mobile phone signal in a targeted manner and improve the shielding effect of the jammer.

The third method is to contact the operator of the base station or indoor mobile phone signal distribution system, and reduce the strength of the mobile phone signal on site by adjusting the transmission power of the base station or the direction of the antenna board, so as to ensure the shielding effect of the mobile phone signal jammer. This method requires communication with the operator, which requires a certain amount of time and cost, but it can fundamentally solve the problem of strong mobile phone signals.
