I. Case Analysis

• Domestic Foreign Cases

5
Case Analysis

• Goal
• Infrastructure
• Confirming the usage of RFID tags in real
  business
• Types of tags in real business, read rates
• Investigating the composition of device types
• tags and readers for diverse environment
• Multi-modal transportation

6
Domestic Cases

• 11 Cases
• National logistics infrastructure project for
  RFID based air import/export
• Postal transportation RFID system
• National logistics infrastructure support project
  for import and export using RFID
• RFID adoption in container terminal
• RFID based special drugs tracking system
• RFID based book transportation pilot project
• Pilot project for effective SCM of clothing
  industry with RFID
• etc

Case Summary

• Device
• Reader and Tags
• Products from domestic and global companies
• HF(13,56MHz), UHF (433MHz, around 900 UHF), 2,45
  GHz
• 18000-6A, 6B
• Passive and eSeal
• Target Objects
• Item, Box, Pallet, Container

8
Case Summary

• Data Accuracy
• Max. 96 in one project
• Data accuracy is not coherent among projects
• Air import and export project
• Variation of Accuracy
• Variance is almost 0 100
• various according to the conditions
• Materials, tag housing, antenna and tag numbers,
  moving speed, angle between tag and antenna,
  Read/Write
• For accurate recognition
• Tags less than 20 and lowest moving speed

9
Case Summary

• Sales store environments
• Recognition Rate (Antenna Location)
• Cart 7390
• Shopping basket 6690
• Recognition Rate (Antenna Type and Cable Length)
• 5M 8693
• 10M 7683
• Roughly, 80 of read rate
• One flagship store of Samsung-Tesco, Seoul
• Drugs tracking
• Item read 90.595.5 (10/20/30/40/50 items)
• Box read 91100 (1/2/3 tiers)

10
Foreign Cass

• Many implementation cases
• HP Experience, WalMart, RFID in defense, groupe
  carrefour
• Good results and recommendable ROI
• Limits on the results
• Business partners and target objects are not
  exposed to real environment
• Internal adoption or experiments
• The details of data and environment are not
  opened

11
Conclusion from Case Analysis(1)

• Generally, Internal adoption of RFID is
  successful
• But hard to guarantee when partners collaborate
  in real business environment
• Data accuracy is various according to environment
• Impossible to control all environmental variables
  or to modify all existing environment

12
Conclusion from Case Analysis(2)

• Think real business environment
• Various types of tags are used
• Frequency bands, passive/active, eSeal, Sensors,
  RTF/TTF
• Multi-modal transportation
• Units of target objects
• Item, box, pallet, container
• The usage of all possible tag data in SSI
• It is more reasonable to introduce the composite
  use of tags, considering real business
  environment including as-is and to-be case
• Tag data from existing and progressing
  international standards, they need to be included
  in SSI for item management

13
II. Data for SSI

• - Data for item management from existing and
  progressing international standards

14
SSI - Infrastructure

• Infrastructure
• a set of interconnected structural elements that
  provides the framework supporting an entire
  structure.
• In other applications information technology
• informal and formal channels of communication
• software development tools
• More general use
• infrastructure provides organizing structure and
  support for the system or organization it serves

Data for SSI

• Data Source
• Assumptions
• Two major users
• End users with service application Data fields
  for AIDC itself
• System administrator Control and management
• Sources
• Memory map
• Protocol Parameters
• Others
• System information
• Commands and responses messages

17
III. Issues

• - Issues in data management data fields and
  processing

18
Issues in Data Management

• Data Fields
• Data Processing
• Response from Scott and Rob.
• Relationships in SSI
• Device Interface, Data management, and ALE
• Order of request and response transmission?
• i) App. ? A.I. ? D.I. ? Interrogator
• ii) Interrogator ? (D.I. ?) D.M. ? A.I. ? App.
• ALE
• Five interfaces
• Read / Wirte
• Tag Memory Specification / Logical Reader /
  Access Control

IV. Next Steps

• Next Steps
• Additional Meeting Proposal

25
Next Steps for Data Management

• Arrangement
• The composition of ALE and other components in
  SSI
• The boundaries and roles of components of SSI
• Selection of Data Fields
• Tag data to be processed in Part 2
• Including data elements from user memory handling
• Adoption of other functions and standards
• Candidates for modification and adoption into
  Part 2
• ALE, 15962, TDT, Tag Data Profile

26
Proposal for additional meeting

• Meeting in Korea
• Sept. or Oct. 2007.
• Members officially invited under RD system
• Other members participation welcomed
• Two goals
• Acceleration of STD progress
• Seminar to Koreans interested in RFID and I.S.
• Governmental sector and companies
