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).

Detailed information
-
Ceiling-mounted access point box When installing an access point in the ceiling, radio wave interference occurs due to reflection on the deck plate surface. This can be prevented while simultaneously adjusting the directionality of the radio waves.
-
Frequency adjustment by plate thickness By changing the plate thickness to match the frequency, it is possible to easily adjust the corresponding frequency.
-
Electromagnetic wave absorber surface It is an electromagnetic wave absorber with excellent performance for oblique incidence, easy on-site processing, and outstanding durability.
-
Non-combustible aluminum shield sheet reflective surface. A non-combustible aluminum shield sheet is applied to the surface to create a reflective surface, while the interior absorbs radio waves and reabsorbs radio waves reflected from the external reflective surface with a radio wave absorber, converting them into heat.
-
Low partition processing An example of use with low partition processing to prevent adjacent interference indoors. It is used to prevent reading errors of electronic tag readers.
