The mobile phone signal indoor distribution system installed in the building where the conference room is located, commonly known as the mobile phone signal amplifier, the mobile phone signal in the conference room will become very strong, then the mobile phone signal indoor distribution system will seriously affect the shielding effect of the conference room signal shielding device. . In this case, if you want to improve the shielding effect of the conference room signal jammer, you can start from the following aspects:
1. Increase the number of signal jammers in the conference room, use multiple units together, and subdivide the frequency of the cell phone jammer used in the indoor distribution system of mobile phone signals to meet the requirements of covering the entire conference room.
2. Use the spectrum analyzer test or the mobile phone signal detection software Cellular-Z (Android phone installation only) to know the frequency band that cannot be shielded by the mobile phone signal blocker in the on-site conference room. The shielding module is used to specifically shield the frequency band with strong mobile phone signals, so as to achieve the effect of shielding these signals by the conference room signal shield.
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 transmit power of the indoor signal distribution system or the direction of the antenna board, or when using the conference room signal shield The power of the cell phone signal distribution system is turned off to reduce the cell phone signal strength in the conference room. So as to ensure the shielding effect of the conference room signal jammer.
4. Remove the antennas of all indoor signal distribution systems within 15 meters around the conference room where the conference room mobile phone signal jammer is used, which can also greatly reduce the signal strength in the conference room and also improve the conference room mobile phone. The shielding effect of the signal shielding device.
The above methods are for reference only, and the actual operation is still subject to the on-site environment.
