Testing the Effectiveness of Conference Room Cell Phone Jammers

Cell phone jammers are increasingly being installed in conference rooms to prevent disruptions caused by phone calls and text messages. However, before installing these devices, it is necessary to test their effectiveness. The testing methods for three different types of conference room cell phone jammers vary, as the environments in which these jammers are used are completely different.

Testing Small Conference Rooms:

Small conference rooms are characterized by their limited area and relatively simple environments. The requirements for cell phone jammers in such rooms are not very high. During testing, simply place the jammer on a desk near the wall and check if the cell phone signals are blocked at the farthest end of the room. This will determine the effectiveness of the jammer in a small conference room.

Testing Medium-Sized Conference Rooms:

Medium-sized conference rooms are usually located on higher floors of buildings. The higher the floor, the stronger the signal from the base station to the conference room. Additionally, indoor signal amplification systems are commonly found in buildings. To meet the signal blocking requirements of medium-sized conference rooms, it is necessary to test the signal strength of various frequency bands and adjust the jammer accordingly. In some cases, increasing the power of certain frequency bands may be necessary. High-power modules can be used to cover the stronger frequency bands, while low-power conference room jammers can be used to block relatively weaker cell phone signals.

Testing Large Conference Rooms:

Large conference rooms, also known as venues, are capable of accommodating hundreds or even thousands of people for meetings or events, such as the Great Hall of the People. The cell phone jammers used in these large venues are not ordinary low-power jammers. These jammers require higher power and more advanced technology to effectively block cell phone signals in such large spaces. Testing and adjusting the jammer in large conference rooms may involve analyzing the signal strength of various frequency bands and increasing the power of specific bands. This ensures that the jammer meets the signal blocking requirements of large conference rooms.


Testing the effectiveness of conference room cell phone jammers is crucial before their installation. The testing methods vary depending on the size and environment of the conference room. Small conference rooms require simple testing, while medium-sized conference rooms may require adjustments to the jammer’s power and frequency coverage. Large conference rooms, on the other hand, demand high-power jammers with advanced technology. By conducting thorough testing, conference room cell phone jammers can effectively block unwanted signals and create a distraction-free environment for meetings and events.
