Friends familiar with mobile phone signal jammers should have encountered such a situation. There is an operator's base station 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 to deal with such a scene, or how to reasonably configure the mobile phone signal jammer.

1. If the prepared Mobile Phone Signal Jammer has a certain interference effect on the site, but the distance does not meet the requirements. If two identical mobile phone signal jammers can be configured, 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, Reasonably allocate the transmission frequency of each module, which can improve the on-site 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 to a strong frequency band of a frequency signal. Cooperate with low-power mobile phone signal jammer to realize full frequency coverage interference of mobile phone frequency band. Through this method, the above method can be realized by using the module with the model of sma-818k90 or the high-power module of sma-818k200 produced by Nanjing Bokang Electromechanical Technology Co., Ltd. This method can save a lot of cost and realize on-site signal interference. Very cost-effective.
