【Over 1000 successful measures】●Before the measures, the electronic tags (RFID) on the apparel store side were being read by the reader on the back-end side, causing disruptions to operations. To resolve this, we spatially separated the areas with a non-combustible SS sheet partition (constructed on the back-end wall to prevent multi-path interference, with ceiling construction depending on the environment), thereby reducing the impact of mutual interference. The non-combustible aluminum electromagnetic wave shielding sheet we used has obtained 'F☆☆☆☆ certification and fire prevention certification (non-combustible: NM-1776)'. With the reinforcement material made of sturdy glass cloth, it exhibits strength that has not been seen before, making it less prone to holes or cracks due to bending during installation, unlike conventional products. The joints and holes are reinforced with SS tape of the same material, enhancing workability and providing excellent shielding performance. It has been used after passing installation performance tests at our EMC experimental building. We receive inquiries and consultations such as "I want to use it in this kind of place?" and "I'm having trouble utilizing it effectively," and we implement and measure the improvements discussed and proposed, reflecting them in our products. 'Smiring Company,' which continuously evolves to meet the diverse needs of this era, is Koyo Sangyo Co., Ltd.

●One day, if the electronic tag (RFID) is affected by interference, I think it would be good to use this guide to take countermeasures. ●Improvements implemented based on issues are published with photos. ●The construction procedure for the wall includes explanations with photos on the overlap of aluminum sheets, the pitch for tacker fixation, and the method of fixing with aluminum tape. ●Measures for leakage from outlets and embedded lighting fixtures that occurred during actual construction are also noted. Due to the recent pressure on radio waves leading to frequency shifts and reorganization, as well as the increase in RFID users and other wireless devices, it is not uncommon for issues such as radio wave interference to occur as a result of these influences. UHF band IC tags have a long communication distance of about 3 to 5 meters, which can lead to interference when multiple IC tag readers are installed in close proximity. In particular, in Japan, the bandwidth allocated to UHF band IC tags is narrow at 2 MHz (for high-output types, while low-output types like handheld devices have 3 MHz), making it difficult to avoid interference. Wireless sensor networks utilize the high radio reach of the 920 MHz band and, through high reliability via multi-hop communication, are accelerating wireless IoT solutions.

【High-Frequency Electromagnetic Wave Absorbing Sheet】 This is a thin sheet that absorbs high-frequency electromagnetic waves. We propose product forms tailored to your needs, including laminated adhesives. This product excels in electromagnetic wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability. It is ideal for countermeasures against TX-RX coupling in modules such as ETC (5.8GHz), X-band (8-12GHz), ship radar (3GHz, 9GHz), proximity radar (24GHz), high-speed wireless transmission (38GHz), high-speed wireless LAN (60GHz), and vehicle-to-vehicle radar (76GHz), as well as for absorbing unwanted radiated noise, addressing misoperation due to ETC multipath reflection, and ghosting issues caused by nearby metal structures in radar applications. 【Electromagnetic Wave Shielding Fabric】 ● Compared to shielding measures using metal, it is lightweight and easy to handle. ● Ventilation holes: High breathability conductive fabric allows for shielding at the hole areas. ● It shields low-frequency magnetic fields, has excellent high-frequency shielding performance, and offers outstanding breathability and flexibility typical of fibers/fabrics. It is lightweight and has excellent processability for sewing and cutting, using polyester threads that do not generate dust.
