Dedicated test system that has full control and observes the IUT's behaviour. Test system simulates the interface to the IUT according to the standard. The tests are performed on accessible standardised interfaces. Conformance Testing of NFC Mobiles ETSI TS 102 230 3GPP 31.121 UICC Simulator ME ISO 7816 ETSI TS 102 922-1 IC-USB ETSI TS 102 694 ETSI TS 102 695 SWP/HCI NFC Device Simulator NFC Forum Digital Protocol Tag Operation NFC-A,-B,-F CLF Interoperability Testing „Interoperability: The ability of two or more systems or components to exchange information and to use the information that has been exchanged.” IEEE glossary The Equipment Under Test (EUT) and Qualified Equipment (QE) come from different suppliers (or, at least, different product lines) Interoperability tests are performed at interfaces that offer only normal user control and observation Interoperability tests are based on functionality as experienced by a user The tests are performed and observed at functional interfaces such as Man-Machine Interfaces (MMIs), protocol service interfaces and Application Programming Interfaces (APIs) Interoperability testing of NFC Mobiles ME UICC Uu ISO 7816 IC-USB SPI, I²C, USB SPI, I²C, USB SWP/HCI CLF NFC Device SE I²C NFC-A,-B,-F Current Status of NFC Conformance Testing ETSI SWP/HCI Test Case Specifications Standardisation - Under control of ETSI SCP Terminal test specifications have been approved beginning of 2010 Specifications - ETSI TS 102 694-1: SWP terminal test specification ETSI TS 102 695-1: HCI terminal test specification (mobiles) ETSI TS 102 965-3: designs) HCI terminal test specification (reference SWP/HCI features as low-level HCI transport, link management gate, administration gate, ACT frames, link establishment and data flow 24 combined tests, requiring NFC device simulator 10 test cases require enhanced analogue measurement capabilities. SWP/HCI Test Case Certification Global Certification Forum (GCF) - GCF approved Work Item #133 introducing SWP and HCI - 40+ tests validated against real handsets Test case list has been agreed and introduced into GCF DCC data base PCS Type Certification Review Board (PTCRB) - PTCRB have issued a Request for Test for what they call NFC testing, covering the same test specifications as GCF WI#133 - First tests validated against real handsets NFC Forum: Compliance Program Objectives Develop a means of establishing compliance with the Forum’s published open standards and interoperability of NFC devices Develop a product certification program with a consumer-recognizable trademark guaranteeing the NFC-brand promise of compliance and interoperability When a device passes certification testing, the N-Mark can be used to indicate the spot on the device where it reads NFC tags.
