1. Overview
| STD Number | ARIB STD-T89 |
|---|---|
| Standard Name | 950MHz-Band RFID Equipment for Premises Radio Station |
| Enactment Date | 05.26.2005 |
| General Description | This standard specifies requirements for the radio equipment used for mobile object identification using radio waves in the frequency between 952MHz above and 954MHz and below defined in the Article 16-2 and 17-2 of the Regulation for Enforcement of Radio Act and in the Paragraph 1 of Article 49-9-1 of the Ordinance Regulating Radio Equipment among premises radio stations in the Article 14 of the Regulation for Enforcement of Radio Act (The related Notification No. 378, 1986, Revision by No. 431, 2005). The subject system is high-output UHF band electronic tag system and technical requirements for radio equipment consisting of interrogator, antenna and transponder are specified. While communications protocol (specification concerning interconnection) between interrogator and transponder is not specified in this standard. As defined in the interim measures for the laws and regulations in 2010, equipment which acquired certification of technical regulations conformity or certification of construction type based on the provisions prior to the revision of the laws and regulations (May 24,2010) before March 31, 2013 is subject to the Version 3.0 not Version 3.1 of this standard. It is noted that this standard is valid until March 31, 2018. |
