Background
• RFID: Booming in China, Large potentials• Chain: R&D←→Testing
←→Apllication• Special interests for China
– Standards: under established– Products: diversity, conform to different
overseas standards – End users: confused with RFID solutions– Other issues: frequency, environment

Architecture
• Performance Testing– Benchmark testing for device
• End users: specification for performance evaluation• Device manufacturers: consultation for performance
parameters design• Test items: speed, orientation, read range, read rate,
number of tags etc.
– Integrated solution testing• System Quality of Service: Network Performance• Technique: Virtual Terminal (device) , Load capability,
Performance monitoring

Architecture
• Conformance Testing– Air interface conformance test
• Basis for RF Communication• Frequency feature: 125KHz~134KHz, 13.56 MHz,
2.45GHz, 860~960 MHz and 433MHz(active)
– Protocol conformance test• Multiply standards: EPC, ISO/IEC, UID• Matching validation• “Recording”: Spectrum Analyzer, ProgrammableSignal Generator,

Architecture
• Security Testing– Wireless Transmission
• Tag-reader communication• Potential adversaries: cloning, intrusion, eavesdropping• Small-signal analysis: feedback signal acquisition
– Network Transmission• Reader-middleware-applications• General network security problem: intrusion, data
security. DoD• Self features: huge and intensive flow, disparity in server
load• Combining classical NS testing techniques with the
simulation of RFID information flow

Approach
• Benchmark testing (e.g. read rate)– Deploy testing scenario– Record environmental parameters– Test read rate at different positions– Analysis test results

Approach
• Integrated solution testing ( field testing )– Application field: complex EM condition– Many factors: media, material, magnet,
speed, distance– Main targets: read probabilities of readers,
reliabilities of tags
