Optimizing the Placement and Installation of Full Band Interference Devices for Enhanced Shielding Efficiency
With the advancement of modern technology, mobile phones have become ubiquitous personal belongings. To ensure fairness during examinations, schools have installed full band interference devices in their exam halls. However, the effectiveness of these devices greatly depends on their placement and installation. This article explores the key factors that influence the shielding efficiency of full band interference devices and provides recommendations for optimal positioning.

1. Placement of Low-Power Full Band Interference Devices:
For low-power full band interference devices, it is recommended to place them on the regular teacher’s podium or desk. This positioning ensures a stronger shielding effect by minimizing any potential obstacles between the device and the mobile phones.
2. Installation Height for Fixed Full Band Interference Devices:
Fixed full band interference devices should be installed at a height of approximately 180cm-220cm from the ground. If possible, a slight forward tilt angle is preferred. This installation height and angle help maximize the effectiveness of the interference device by reducing signal attenuation caused by obstacles or walls.
3. Distance from Communication Base Stations:
The distance between the interference device and communication base stations significantly affects its shielding efficiency. The farther the full band interference device is from the base station in the application environment, the better the shielding effect. It is crucial to consider this factor when selecting the installation location.
4. Coverage Area:
The size of the area that needs to be shielded determines the power requirements of the interference device. In smaller classrooms, low-power full band interference devices are sufficient, while larger areas may require high-power shielding devices. Careful consideration of the coverage area ensures the appropriate selection of the interference device.
5. Proper Handling and Maintenance:
To maintain the optimal performance of full band interference devices, it is essential to avoid placing any objects in front of the device during operation. Additionally, tampering with the device, such as removing its internal antenna, can lead to damage and compromise its effectiveness. Adhering to proper handling and maintenance guidelines is crucial for the longevity of the interference device.
6. Outdoor Installation Considerations:
When installing interference devices outdoors, it is important to ensure they are protected from water, dust, and insects. These environmental factors can potentially damage the internal components of the device, thereby reducing its lifespan and effectiveness.
Conclusion:
The effectiveness of full band interference devices in exam halls relies on various factors, including their placement, installation height, distance from communication base stations, coverage area, proper handling, and outdoor installation considerations. By carefully considering these factors, educational institutions can optimize the shielding efficiency of these devices, ensuring fair and secure examination environments.
