Understanding the Different Types of Meeting Rooms and Signal Blockers

Exploring the Requirements and Challenges of Signal Blocking in Small, Medium, and Large Meeting Rooms

Meeting rooms are essential spaces for conducting conferences, seminars, and other professional gatherings. Depending on their size, meeting rooms can be categorized as small, medium, or large. Each category presents unique challenges when it comes to signal blocking, requiring different approaches and equipment. This article aims to provide an overview of the requirements and considerations for signal blocking in each type of meeting room.

Small Meeting Rooms:

Small meeting rooms are characterized by their limited size and relatively simple environment. The requirements for signal blocking in these rooms are not as demanding. During testing, it is sufficient to place a signal blocker on a desk near the wall and check if the signal from a test phone is blocked at the farthest point from the blocker.

Medium Meeting Rooms:

Medium-sized meeting rooms are usually located on higher floors, where the signal strength from base stations is stronger. Additionally, indoor signal amplification systems are commonly installed in these buildings. To meet the signal blocking requirements in medium-sized meeting rooms, it is necessary to test the signal strength of various frequency bands and adjust the signal blocker accordingly. This may involve increasing the power of certain frequency bands. High-power modules can be used to cover the stronger signal bands, while low-power signal blockers can be employed to block weaker phone signals.

Large Meeting Rooms:

Large meeting rooms, also known as venues, are capable of accommodating hundreds or even thousands of attendees, such as the People’s Great Hall. Signal blockers used in these venues are not ordinary low-power devices. High-power signal blockers are required to cover the entire venue and effectively block phone signals. Furthermore, the signal strength of all phone signal frequency bands within the venue needs to be assessed. By adjusting the signal strength of the transmission source, the aim is to reduce the phone signal levels in the venue, allowing the signal blocker to function optimally.


Understanding the different types of meeting rooms and their signal blocking requirements is crucial for ensuring effective communication management during professional gatherings. Small meeting rooms have simpler requirements, while medium-sized rooms necessitate adjustments based on signal strength and frequency bands. Large meeting rooms, on the other hand, require high-power signal blockers to cover the entire venue and reduce phone signal levels. By employing the appropriate signal blocking equipment and techniques, organizers can create an environment conducive to focused discussions and productive meetings.
