SMEs are worried about

• Whether or not RFID hardware performance
  (effective radiated power, frequency etc.) meets
  the local regulations
• How to select RFID devices that can fit the
  specific application requirements
• How to deploy RFID hardware in real environment
  to achieve maximum efficiency

How to deploy a RFID system becomes
increasingly important due to the variety of RFID
technology and complexity of its application
environment

Challenges in RFID deployment

• Frequency is different in different countries,
  and RFID hardware performance is changed with
  different central frequency
• Environment influences RFID hardware performance
• tag attaching material paper, wood, plastic,
  metal, liquid
• antenna installation orientation, distance,
  height
• tag placement, number of tags, tag moving speed
• uncertain factors in real environment
• Difficulties in on-site deployment
• tag-antenna matching labor and time consuming,
  lack of experiences
• reader (antenna) number cost a lot, difficult to
  deploy all for testing
• Furthermore, what is good solution is
  application-specificROI analysis needed

Challenges in RFID deployment

• To build a knowledge base for robust RFID
  solution models with common sense that can be
  leveraged upon across industries and different
  deployments, thus shortening the learning cycle,
  deployment time and reducing cost. It is an
  important reference for SMEs to learn RFID and to
  deploy RFID.

Two tasks

• RFID benchmarking test
• oriented to various products, various
  environment, various applications, in order to
  collect valuable raw data.
• RFID deployment simulator
• in order to utilize the test results, it analyzes
  test data using data mining and machine learning
  technologies, in order that customers could know
  the application effect in a visual way, and
  provides ROI report to remove the customers
  worries before they deploy RFID.

Deployment Scheme
Scheme add reader3 for reader1 add reader4 for
reader2. Event ( READ(reader1, reader3)gt1 )
AND ( READ(reader2, reader4)gt1 ) Result event
success rate 98
event success rate can be improved by a better
deployment scheme.
