Enhancing the Shielding Effectiveness of Full Band Interference Detectors in Meeting Rooms

Strategies to Improve Signal Blocking in the Presence of Strong Mobile Phone Signals

In meeting rooms, the strength of mobile phone signals can often be attributed to the proximity of nearby base stations or the installation of indoor mobile phone signal distribution systems, commonly known as signal amplifiers. The effectiveness of full band interference detectors in blocking signals is primarily influenced by the presence of surrounding base stations and indoor signal distribution systems. This article explores several approaches to enhance the shielding effectiveness of full band interference detectors in meeting rooms.

1. Increasing the Number of Interference Detectors:

To achieve the requirement of covering the entire meeting room, one can consider deploying multiple interference detectors in coordination. By increasing the quantity of interference detectors, the coverage area can be expanded, thereby improving the overall shielding effectiveness.

2. Targeting Strong Signal Frequencies:

By utilizing spectrum analyzers or mobile signal detection software such as Cellular-Z, it is possible to identify the frequency bands with the strongest mobile phone signals at the site. Based on the frequency parameters obtained from the tests, high-power shielding modules can be designed specifically to block these strong signal frequencies. This targeted approach ensures that the full band interference detector effectively blocks signals in these identified frequency bands.

3. Collaboration with Base Stations and Signal Distribution Systems:

Contacting the operators of base stations or indoor mobile signal distribution systems can be beneficial in reducing the strength of mobile phone signals at the site. Adjusting the transmission power of base stations or modifying the direction of antenna panels can help lower the signal intensity, thereby ensuring the shielding effectiveness of the full band interference detector. Additionally, collaborating with low-power devices can be considered to enhance suppression effects in specific frequency bands with stronger signals. Each channel of the interference detector can be equipped with a transmitting power of 10-20W, and the selection of modules can be customized accordingly.


In meeting rooms where strong mobile phone signals are present, it is crucial to employ effective strategies to enhance the shielding effectiveness of full band interference detectors. By increasing the number of interference detectors, targeting strong signal frequencies, and collaborating with base stations and signal distribution systems, the overall performance of the interference detectors can be significantly improved. These measures ensure a more productive and interference-free environment for meetings and conferences.
