Before installing a full band signal blocker, it is necessary to test its effectiveness. Through testing, we can determine whether the signal blocker meets the shielding requirements of the entire meeting room and also determine the number of blockers needed. In order to test the full band signal blocker, certain tools and equipment are required, including a screwdriver, power strip, ladder, and three mobile phones from different carriers. Additionally, a spectrum analyzer is needed for professional detection.
Testing Procedure:
- Prepare the necessary tools and equipment mentioned above.
- Find the nearest AC power socket and connect the power strip.
- Place the power strip in the location where the signal blocker will be placed in the meeting room. It is recommended to position it near the windows on both ends of the room, preferably at a higher level. If the conditions are limited, it can be placed directly on the conference table, but avoid placing it on the floor.
- Connect the power strip to the signal blocker and turn on the switch.
- Choose a location in the meeting room opposite to the signal blocker or diagonally across from it.
- Place the mobile phone on the table and let it remain idle for 1-2 minutes.
- At the same time, turn on the spectrum analyzer placed on the same table to check if the signal blocker is outputting signals in all frequency bands.
- After 1-2 minutes of idle time for the mobile phone, check if there is a signal displayed on the phone. If there is no signal, it indicates that the phone has been blocked in that position. Move slightly closer to the direction of the signal blocker and repeat the above steps until the phone is successfully blocked.
Conclusion:
Testing the effectiveness of a full band signal blocker is crucial before installation in a meeting room. By following the testing procedure mentioned above, one can determine if the signal blocker meets the requirements and ascertain the number of blockers needed. This ensures a successful implementation of signal blocking technology in meeting rooms, providing a disturbance-free environment for important discussions and presentations.
