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

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

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.

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

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

Submission

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

Differentiation from TGkTGk 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

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
