ISOIEC 18000-3 HF RFID standard for item management

ISO/IEC 18000-3 HF RFID standard for item management

Among ISO/IEC standards, ISO/IEC 18000-3 is an international standard for all the wireless devices operating at 13.56 MHz frequency and determines how a wireless device reading the RFID or NFC tag should interact, connect and communicate with each other.   

According to ISO/IEC, the scope of this standard is to deliver communication solutions, anti-collision management systems, physical layer protocol keys for RFID systems, thus playing an important role in item-level identification, logistics, retail, transport, manufacturing, airline baggage, etc. In short, it explains air interface communication parameters working at 13.56 MHz frequency.

ISO/IEC 18000-3 explains three modes consisting of non-interfering nature; Mode 1, Mode 2 and Mode 3. Let’s us discuss all of them;

  1. Mode 1: It depends on ISO/IEC 15693 that is used for the communication of contactless integrated vicinity cards. RFID manufacturers use Mode 1to acquire a guideline and requirement checklist for HF RFID interrogators. ISO/IEC 18000-3 Mode 1 also practices changes and additions to target inventory management market effectively and to enhance the compatibility between RFID vendors. It follows the ‘‘Reader Talk First’’ scheme to describe the Read/Write system.
  2. Mode 2: It is used as a high-speed air interface. It is not interoperable with Mode 1 and Mode 3 of ISO/IEC 18000-3. Furthermore, Mode 2 is also non-contending with all the remaining modes of ISO/IEC 18000-3.
  3. Mode 3: It also acts as a high-speed air interface with two options; ASK based option and PJM based option. Both of these options of Mode 3 utilize the 18000-6C command structure to become compatible with the Electronic Product Code (EPC).  

ISO/IEC recommends that users must use any of the single-mode to target their application or else they must know the fact that whether their selected modes are interoperable or not. 

ISO/IEC is a standardized series developed by International Standard Organization to offer an infrastructure for defining common communication protocols, helping the industries to deploy useable RFID (Radio Frequency Identification) frequencies. ISO/IEC proposes solutions to implement the same protocols for different frequencies while eliminating the interference problems from one frequency to another. It permits the business owners to limit software complexities, deployment costs and enables them to control, monitor and exchange information at long distances. For example,

  1. ISO/IEC 18000-1 explains all the concepts that lie behind ISO/IEC 18000-3:2010. It supports and encourages the role of RFID employment without making any outcomes that are associated with technical requirements of any possible options for any specific applications.
  2. ISO/IEC 18000-2 determines the wireless medium for RFID devices operating at less than 135 kHz frequency. The objective of this ISO/IEC 18000-2 standard is to deliver certain technical provision for RFID devices that can be exploited by ISO associates for designing standards for RFID applications.
