Radio wave absorber IT foam directional radio wave absorber Wi-Fi countermeasures

Radio wave absorber IT foam directional radio wave absorber Wi-Fi countermeasures

It is an electromagnetic wave absorber made of olefin-based resin foam, which exhibits excellent effects in suppressing wideband characteristics, is easy to cut and install on-site, and reduces multipath.

- 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).
