When testing the mobile phone signal jammer, everyone should have encountered such situations: there is a base station of an operator near the use site, or an indoor signal distribution system is installed in the corridor. As a result, the interference effect of the mobile phone signal jammer is greatly affected. How should we deal with such a scene, or how to reasonably configure the mobile phone signal jammer?

1. If the mobile phone signal jammer prepared in advance has certain interference effect on the site, but the interference distance does not meet the requirements, if two mobile phone signal jammers can be configured to solve the problem, configure two, or use the spectrum analyzer to detect the signal spectrum on the site, find out the signal frequency that is most difficult to interfere through analysis, and then add the interference module of the corresponding frequency band in the mobile phone signal jammer, and then disperse the frequency distribution, Reasonable allocation of the transmission frequency of each module can improve the field interference effect.

2. If the first method still fails to achieve the expected interference effect, a high-power interference module can be used to supplement the targeted interference on a signal band with strong frequency signal. Cooperate with low-power mobile phone signal jammer to realize full frequency coverage jamming of mobile phone frequency band. Through this method, the high-power module of this frequency band can be used to realize the above method. This method can save a lot of costs, and can achieve on-site signal interference, with higher cost performance.
