The indoor distribution system of mobile phone signal is installed in the building where the conference room is located, and the mobile phone signal in the conference room will become very strong. At this time, the indoor distribution system of mobile phone signal will seriously affect the interference effect of the Signal Jammer in the conference room. In this case, if you want to improve the interference effect of the Signal Jammer in the conference room, you can start from the following aspects:

1. Increase the number of signal jammers in the conference room, use multiple devices together, and subdivide the signal frequency used by the distribution system in the mobile signal room, so as to meet the requirements of covering the whole conference room.

2. Through the spectrum analyzer test or the mobile phone signal detection software cellular-z (only for Android mobile phone installation), we can know the frequency band that the mobile phone signal jammer in the on-site conference room cannot interfere with. According to the tested frequency parameters, we can make a high-power signal interference module of this frequency band to specifically interfere with the frequency band with strong mobile phone signals, so as to achieve the effect that the conference room Signal Jammer interferes with these signals.

3. You can contact the operator of the indoor mobile phone signal distribution system to reduce the on-site mobile phone signal strength by adjusting the transmission power of the indoor signal distribution system or adjusting the direction of the antenna board, or turn off the power of the indoor mobile phone signal distribution system during the use of the conference room Signal Jammer to reduce the mobile phone signal strength in the conference room. So as to ensure the shielding effect of the Signal Jammer in the conference room.

4. Remove the antennas of all indoor signal distribution systems within 15 meters around the conference room where the mobile phone signal jammer in the conference room is used, which can also greatly reduce the signal strength in the conference room and improve the interference effect of the mobile phone signal jammer in the conference room.
