Introduction to the Software Active Tagging Joint Requirements Group SAT JRG November 23, 2009

© 2009 GS1 Introduction The Software Active Tagging JRG is not a typical JRG that would produce user requirements based on business use cases. The SAT JRG shall develop a technical analysis of the existing ratified SAG interface standards and determine how they are impacted by the approved Active Tagging requirements and analysis from the Hardware Active Tagging Ad Hoc Committee. The analysis shall include what work needs to be completed to update the software stack to enable the stack to manage data from active tags. 2

© 2009 GS1 Active Tagging Software JRG We need to protect the IP, and the JRG structure allows us to create an open forum where anyone in the EPCglobal subscriber community can participate while protecting potential IP. The output from this group will be used to create or revise charters for the impacted SAG Working Groups. The SAT JRG will use the input from the Hardware Active Tagging ad hoc committee as a starting point. CHARTER

© 2009 GS1 4 HAT Work To-Date HAG Active Tagging ad hoc Committee (HAT) reviewed the Active Tagging Joint Requirements Group (AT JRG) User Requirements document v1.6 and AT JRG chart of air interface protocols (AIPs). The HAT assembled an expanded list of candidate AIPs to also include those AIPs that members felt necessary to also review for due diligence. The HAT turned the user requirements into a general set of technical “Review Criteria”. Each candidate AIP was presented by a HAT member with in- depth technical knowledge about that AIP. The presentations must answer the Review Criteria, and there was an accompanying Q&A session with each presentation. Presentations are completed. The HAT is now evaluating the sum of information to provide a Recommendation to the EPCglobal Board.
