The cause of the issues in the Wi-Fi environment may be the neighboring Wi-Fi signals entering through the window. By properly shielding unnecessary signals with window glass, you can comfortably improve the unstable wireless LAN indoors.

Electromagnetic Wave Shielding Film *Wi-Fi Environment Improvement Measures *Wireless Radio Environment Improvement Measures ● By improving the radio wave environment in windows and indoors, it is possible to bring 5G traffic indoors without causing interference with Wi-Fi 6. Additionally, when applying for a local 5G license, interference adjustments between adjacent local 5G base stations and devices are required based on the radio law-related examination standards. The only solution for the weakest point, window glass, is the electromagnetic wave shielding window film. ● With a visible light transmittance of 70%, it exhibits high transparency while demonstrating excellent heat shielding properties. ● It provides a shielding effect of 25-30 dB, with high transparency and excellent electromagnetic wave (electric field wave) shielding effectiveness, helping to block harmful waves and reduce interference from Wi-Fi 6, 5G, local 5G, etc., thus aiding in countermeasures against speed reduction, delays, and leaks. ● It reflects over 90% of infrared rays (solar heat) contained in sunlight, cuts 99% of ultraviolet rays (UV), and has a high light selectivity with a light efficiency of 1.4 (for 73FG), ensuring low reflection below that of glass without compromising appearance.

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.

【SS Sheet: Fireproof Material Certification Number (Non-combustible: NM-1776) F☆☆☆☆ Certification】 ● Reduction of RFID and WiFi signal interference ● Aluminum sheet reinforced with glass cloth ● Both sides are aluminum, providing unprecedented strength, making it less prone to holes or cracks from bending during installation, and excellent in workability. In case of emergencies, the joints and holes can be reinforced with conductive aluminum tape of the same material, enhancing the shielding performance. 【SS Tape】 ● Reinforcement of gaps between shielding materials, repair of holes, reinforcement of metal connections, and around openings (for shielding joints, shielding construction repairs, and joining metal to metal)

- Measures against Wi-Fi signal interference and wireless radio signal interference are supported. - Can be used as a countermeasure against RFID tag interference. - UHF band IC tags are being widely adopted, especially in logistics applications, due to their convenience of being able to read a large number of IC tags over a wide area. However, because their communication range is several meters long, they often read IC tags that are not intended to be recognized. - To prevent misreads, shield curtains, shield roll screens, and shield Roman shades are optimal. - Shield roll screens are a roll screen type that can be retracted and stored when not needed, allowing for accurate reading of IC tags without obstructing the flow of objects or people.

- It is capable of wideband radio wave absorption from 300 MHz to 110 GHz and excels in radio wave absorption performance for oblique incidence. It is easy to cut and process, making installation at the site straightforward. - It is an electromagnetic wave control material and radio wave absorber effective for wireless technology, EMC, and noise countermeasures. - Made primarily from polyolefin-based resin and carbon, it can be produced in suitable thicknesses depending on the applicable frequency. - Wireless LAN access points stored in the ceiling can cause interference due to reflected waves from the deck plate within the ceiling, so the radio wave absorption box cuts off upward radio waves, enhances the directionality of downward waves, and absorbs excess radio waves. - Installing it on adjacent partition walls in the same floor tenant prevents radio wave interference and secures channels. - Near glass windows, it prevents radio wave leakage to the outside and, when used in conjunction with shielding films and floor SS sheets, reduces radio wave interference between floors and inside and outside. - The box for wireless LAN access points, when combined with SS sheets, prevents radio wave interference. - It is used as an electromagnetic wave control material for adjusting wireless LAN access point equipment during system installation (used to isolate and adjust several units at hand).

We measure the electromagnetic environment of buildings such as companies, factories, and hospitals, which may be concerned about equipment malfunction or health hazards to humans due to electromagnetic wave interference. We also offer measurements of the shielding effectiveness at installation sites for MRI and CT machines, as well as surrounding electromagnetic environments. 1) Magnetic Field Measurement When it is necessary to know the magnetic field environment in advance, such as for the installation of devices that are susceptible to magnetic field influences, please make use of our environmental measurement services. 2) Examples of On-Site Measurements - Installation sites for electron microscopes - Installation sites for semiconductor manufacturing equipment - Installation sites for hospital equipment and testing devices - Near power transmission lines - Near transformers - In areas around apartment buildings or residential construction sites where there are nearby power transmission lines or substation facilities 3) Classification of Environmental Magnetic Fields - DC Magnetic Fields Magnetic fields leaking from permanent magnet application devices (such as speakers), magnetic fields generated by DC large currents from lightning or welding machines, strong electromagnets (such as lifting magnets), and geomagnetic fields. - AC Magnetic Fields Magnetic fields from power transmission lines and substation distribution equipment at commercial frequencies. - Fluctuating Magnetic Fields Transient magnetic field changes caused by the passage of trains or vehicles, disturbances in magnetic fields due to the operation or shutdown of electrical equipment and devices.
