1 What is RFID? Lisa Petrini

2 A Tool Real-time Information Monitor Assets Remove Human Interaction Serialize Data

3 What is in it for my organization? Reduced Costs Improved Quality Improved Customer Satisfaction

4 Show me the money! Toyota Beat General Motors March billion Profit GM1.97 billion (Loss) billion (Loss) 1970: 2% MS. 2006: 13% HBR,July-August 2007

5 Do they use RFID? let us not focus on developing low-cost automobiles; let us develop technologies and processes that will allow Toyota to manufacture all our vehicles at lower costs. -Katsuaki Watanabe, CEO, Toyota HBR, July-August 2007

6 More Specifically, What is it? A network of Interrogation Zones.

7 Interrogation Zone Components Environment Physics Hardware Middleware Application

8 Environment Ever Changing Different environments within the organization Changes in processes or products alter accuracy of equipment

9 Physics Frequency Crest to crest Resonance coupling

10 Hardware Transponder (Tag) Antenna Transceiver (Reader)

11 Transponder: Tag Microchip antennas

12 Antenna Wakes up chip Reads/writes information to/from transponder

13 Transceiver: Reader Filters duplicates Back chatter Collects reads Transmits to a reader interface platform

14 Reader Interface Layer: Middleware Route/integrate data to existing SCM, ERP, WMS, or CRM systems. Partner Integration

15 Components of an Interrogation Zone Insert diagram including the middleware

16 Application/Utilization/Expansion Big Picture/Details One node at a time Expansion to entire organization

17 Where to start? 1. Develop a cross functional team 2. Map business processes 3. Evaluate physical infrastructure 4. Evaluate IT infrastructure

18 Cross-Functional Team Engineers Electricians Maintenance Dept. Operations Information Technology

19 Map Business Processes Raw goods, distribution channels, and asset management Automate human tasks Eliminate errors Real-time data capture

20 Physical Infrastructure Relocate equipment Antenna design Hand held readers or conveyer belt readers

21 IT Infrastructure Existing Enterprise Systems Power supplies Backups Maintenance procedures

22 Developing your RFID A Site Assessment Lab Reader selection Reader Interface selection

23 Site Assessment Site Assessment Identify possible sources of Ambient Electromagnetic Noise (AEN) Remove the source or work around it. Full Faraday Cycle Analysis Spectrum Analyzer ¼ or ½ wave dipole antenna and ground plate

24 Site Assessment Tripod Stand Laptop Computer

25 Full Faraday Cycle Test Set up dipole antenna on ground plane and attach to tripod so you are in the center of the target area. Connect the above to the spectrum analyzer with a coax cable.

26 Full Faraday Cycle Test Attach the laptop with a Ethernet cable and power up. Power up spectrum analyzer and tune it to center frequency of 915 MHz. Set the span to 60 MHz. Set resolution bandwidth to 100kHz. Set video bandwidth to 30 khz. Set amplitude attenuation to 0dB. Turn on maximum hold.

27 Full Faraday Cycle Test Identifies ambient electromagnetic noise. Log for the full business cycle Create real situations that occur

28 Full Faraday Cycle Test Map out interrogation zones on CAD drawings or blueprints To be proactive do the same set-up but in a mobile situation and test the facility watching for noise. This will allow for addition of more nodes later Add all possible business processes to your test. Remove or work around possible interferences.

29 Design your Interrogation Zone Propagate RF waves Contour map

30 Propagate and Map NEED: Spectrum analyzer Signal generator Polarized UHF antenna ¼ wave dipole & ground plate Two tripod stands Laptop computer What it does: Tells how well RF wave travels back to be heard by reader s antennas. Facilitates choosing, configuring, and testing readers.

31 Lab Choices Third-party lab Build your own in-house lab; core competency Hybrid

32 Reasons for a Lab Antenna Patterning Test Reader Performance Test SKU testing Tag Characterization Test

33 Tag Testing Placement Tag type Interaction Start on high power and gradually reduce. Map results on a matrix for later comparison.

34 Tag Encoding Data: Application: Preapplication Post-application Manual Automated Inline

35 Reader Selection Determine costs involved Test reader performance Assess connectivity

36 Middleware Selection Reader and device management Data management Application integration Partner integration

37 Middleware Selection Process management and application development Packaging RFID content Architecture scalability and administration

38 Middleware success Understand physics then design middleware around your infrastructure

39 Now you know What it is Basics of how to

40 You have some decisions to make. What components? Where to implement? What design?

41 The most important decision? WHEN
