5 doc.: IEEE 802.11-03/0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 5 Joint Meeting with TGk Presentation by Worstell 11-03-0950-00-0wng-need-managed-ieee-802-11-devices.ppt Straw Poll: 57/1/9 on forming a SG to look into management of wireless devices Topics discussed –Antenna Selection, load balancing, rogue and service handling, client roaming and dynamic adaptation of clients were discussed. 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

6 doc.: IEEE 802.11-03/0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 6 WNG motion #1 Move that WNG request 802.11 Working Group to form a Study Group for IEEE 802.11 ESS Mesh Results: 50/0/9

7 doc.: IEEE 802.11-03/0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 7 History of ESS Mesh Discussions in 802.11 WNG Technical presentations and discussions have taken place at every meeting since March Candidate PAR and 5 Criteria have been discussed in WNG: –802.11-03/759r2 and 802.11-03/760r3 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

8 doc.: IEEE 802.11-03/0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 8 Scope of Proposed 802.11 ESS Mesh Study Group The proposed study group will investigate the need to extend IEEE 802.11 for providing an Extended Service Set (ESS) Mesh with an 802.11 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 802.11 Working Group so that a Task Group can be formed.

9 doc.: IEEE 802.11-03/0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 9 Motivation for IEEE 802.11 ESS Mesh Standardization Mesh topologies are applicable to both mobile and fixed-infrastructure environments Potential benefits: –Extended range and coverage, without requiring additional wires (convenient deployment, cost) –Enhanced redundancy, reliability –Efficient utilization of limited radio channel capacity –Interoperability

10 doc.: IEEE 802.11-03/0849r1 Submission Nov 10-14, 2003 TK Tan, Philips, Bruce Kraemer, Intersil, Slide 10 WNG motion #2 Move that WNG request 802.11 Working Group to form a Study Group for Wireless Performance Prediction (WPP) Results: 36/14/15

11 doc.: IEEE 802.11-03/0849r1 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 802.11 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

12 doc.: IEEE 802.11-03/0849r1 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 802.11 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

13 doc.: IEEE 802.11-03/0849r1 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 802.11 protocols TGk defines measurements that are done by the devices themselves WPP defines measurements done to the devices

14 doc.: IEEE 802.11-03/0849r1 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 802.11WG
