4. 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

5. 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- specific — ROI analysis needed

6. 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.

7. Real System Simulator modeling simulation Structure for modeling devices and events claimed to represent real system Software for executing model Model test data acquisition Experimental frame specifies conditions under which the system is experimented with and observed Simulated/on-site Test Motivation deployment

8. 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.
