The "RFID Test Bed" facility for the development and demonstration of RFID radio wave propagation characteristics is one of the largest in Japan as a permanent RFID evaluation facility.
This is an "RFID Test Bed" facility for the development and demonstration of technology related to RFID radio wave propagation characteristics. It consists of a large radio wave anechoic chamber (6.5m × 4.5m × H3.4m) and a dedicated broadband RFID reader/writer along with transmitting and receiving antennas, allowing for precise evaluation of large managed objects in conditions close to actual installation environments. ◆ It is one of the largest permanent RFID evaluation facilities in Japan. ◆ It is available for use by any companies, schools, or research institutions involved in RFID research, development, and business. * This test bed was established as part of the new technology development facility (IoT test bed) project of the National Institute of Information and Communications Technology (NICT), which was selected for funding on March 13, 2020.

basic information
<Features of the Shared RFID Test Bed> The impact of materials to which RF tags are attached on UHF band RF tags includes electromagnetic loss due to absorption of radio waves in the case of metal materials and moisture, and in the case of dielectrics, the influence on the antenna performance within the RF tag due to their dielectric constant. The latter can lead to a decrease in reading sensitivity as the peak sensitivity frequency of the tag deviates from the frequency around 920 MHz, which is designated for UHF band RFID in Japan. Therefore, even for large managed objects, it is necessary to select RF tags that correspond to their materials and configurations, and in some cases, design RF tags with the assumption that the peak sensitivity frequency may shift (so that the peak frequency in the attached state is around 920 MHz). To conduct such development/evaluation, it is essential to accurately measure the frequency characteristics of RF tags in an anechoic chamber and to precisely understand the effects of radio wave reflection and absorption under conditions that closely resemble reality, such as when multiple managed items are arranged.
Price information
Since this is a shared facility, we will charge a usage fee, but in order to contribute to the spread and development of RFID, the pricing is set to be very "affordable" compared to regular anechoic chambers. We also provide measurement support. For more details, please contact us at the information below. 【Contact】 Miyakawa Seisakusho Co., Ltd. RFID Test Bed Reception: rfid.tb@msk.co.jp

Detailed information
-
This is an image and photo of the measurement environment for the RFID testbed. A measurement environment for TIPP can also be constructed.
-
The composition of the object to which the RFID tag is attached (such as paper, wood, rubber, or metal) causes a shift in the peak frequency (resonant frequency) of the reflected radio waves from the RFID tag, resulting in a decrease in reading sensitivity.
-
The RFID test bed has a calibrated measurement environment that allows for the acquisition of highly accurate measurement data.
