Mobile phone jammer is used in the conference room, but the effect is poor. How to solve it?

  • 2022-06-30

After the technicians carried professional instruments to detect the signal strength around the conference room, it was found that the antenna for indoor signal distribution was installed in the ceiling of the corridor of the conference room, and through spectrum analysis, it was found that the indoor signal distribution system was indeed installed by one of the operators, which led to the poor interference effect of the mobile phone jammer on the mobile phone in the conference room.


Resolvent:

1. Let the user contact the operator of the indoor signal distribution system and negotiate to turn off the power supply of the indoor signal distribution system installed in the building where the conference room is located during the meeting in the conference room, so as to reduce the signal strength of the mobile phone in the conference room, so as to improve the interference effect of the mobile phone jammer, and then resume the normal operation of the indoor signal distribution system after the meeting. Or inform the operator to remove the antennas of all indoor signal distribution systems within 20 meters around the conference room. This method can also reduce the mobile phone signal in the conference room to a certain extent, so that the mobile phone jammer can interfere with the mobile phone signal in a larger area.

2. Carry out on-site detection through professional instruments to detect the frequency band that cannot be covered by the small power mobile phone jammer, and then select the high-power jamming module of the corresponding frequency band to carry out targeted interference. Compared with the first method, the cost of this method will increase, and the operation is more professional, and whether the user is willing to increase the cost should also be considered.
