Countermeasures for Wireless LAN Network Interference in the 5G Era: Composite Use Cases of Non-combustible Aluminum Sheets + Radio Wave Absorbing Body Box / Heat Insulating Transparent Electromagnetic Wave Shielding Film.
1) "Wireless LAN Access Point Storage Box"
- Controls the direction of radio wave emission to prevent interference, and prevents interference caused by reflections on metal floor surfaces within the ceiling, making it essential for ceiling-mounted access points.
- Allows for easy adjustment and relocation of the AP position after installation.
- Thickness can be adjusted according to the frequency band used, enabling optimal radio wave absorption.
2) "Heat-Reflective Transparent Electromagnetic Wave Shield Window Film"
- Reflects over 90% of infrared rays (solar heat) contained in sunlight and cuts 99% of ultraviolet (UV) rays.
- Offers a high light selectivity with a light efficiency of 1.4 (for 73FG), which is unmatched by other companies, demonstrating high heat-reflective properties while remaining transparent. It is a high-performance mirror type that can reflect infrared rays, with a visible light reflectance of less than 10%, preserving appearance, and provides an electromagnetic wave (electric field wave) shielding effect of 25-30 dB.
- When used in combination with the adjustment of the installation position of the "Wireless LAN Access Point Storage Box," high attenuation effects are observed in cases of exterior walls: metal curtain walls / structural floors: metal deck plates, etc.
3) In cases where the exterior wall is RC (reinforced concrete) and ALC (autoclaved lightweight concrete), there is no shielding performance, so a composite measure involving the installation of non-combustible aluminum sheets will be implemented.
