Electromagnetic wave shielding curtain, electromagnetic wave shielding roll screen.
"Electromagnetic wave shielding curtains" prevent misreading of nearby non-target IC tags in logistics and production sites that use RFID electronic tags.
- 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.
basic information
We have a proven track record in electromagnetic wave shielding measures for windows and entrances, shielding measures through direct wave blocking with partitions, noise countermeasures for medical equipment in hospitals and machinery in factories, and measures against radio wave interference such as with wireless LANs.

Detailed information
-
Live restaurant glass surface (night view) There is a huge glass surface measuring 9 meters high and 16 meters wide behind the stage inside the restaurant, designed to provide a view of the outside. On the other hand, there is a significant challenge of how to escape from interference from external radio waves.
-
Live restaurant performance stage (curtain closed) To create an electromagnetically shielded space within the store, it is necessary to cover all six surfaces of the store's walls, floor, and ceiling with highly conductive materials. Furthermore, all surfaces must be electrically connected without any gaps. A major issue was the presence of glass sections. At the same time, we decided to proceed with a final target value for the shield of 30 dB.
