How will dot 11 devices get managed? At Vancouver meeting, a SG request will be made in WNG SC. Discussions on WPP and how it differs from TGk

doc.: IEEE /0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 7 History of ESS Mesh Discussions in WNG Technical presentations and discussions have taken place at every meeting since March Candidate PAR and 5 Criteria have been discussed in WNG: – /759r2 and /760r3 Next logical step is to form a SG to provide the membership with an opportunity to refine the scope and constraints for a mesh TG

doc.: IEEE /0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 8 Scope of Proposed ESS Mesh Study Group The proposed study group will investigate the need to extend IEEE for providing an Extended Service Set (ESS) Mesh with an Wireless Distribution System (WDS) that supports efficient broadcast/multicast and unicast delivery over self- configuring multi-hop topologies. The expected outcome of the SG is a PAR and a 5 Criteria document that will be submitted to the IEEE Working Group so that a Task Group can be formed.

doc.: IEEE /0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 11 Motivations Currently there is no generally accepted method for predicting or evaluating performance of systems –The metrics and methodologies used are inconsistent –Measurement efforts thus provide widely varying results – non uniformity Need a common set of tests to measure and predict performance of the end device

doc.: IEEE /0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 12 Expectations from the SG Common metrics and test methodology definition –Usable during development of implementations that adhere to standards –Tests that combine the industry best practices that can be used consistently across different devices, while still enabling each device to optimize on the metrics based on its own objectives

doc.: IEEE /0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 13 Differentiation from TGk TGk is about live measurements to aid management and tuning of the wireless network during operation WPP is about off-line performance measurements and tests TGk defines protocol aspects WPP does not define protocols TGk defines measurements that are done by the devices themselves WPP defines measurements done to the devices

doc.: IEEE /0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 14 Conclusion Industry benefits from a uniform set of wireless performance prediction metrics and tests –Developers, Customers, End Users, Reviewers Enable Fairness –Provide the uniform set of rules for evaluations Systematize the functional requirements and comparison criteria for future SGs/TGs in WG

This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period.
