1 Status, Next Steps and Call to Action
May 2005 doc.: IEEE /378r3 May 2005 Status, Next Steps and Call to Action Date: Authors: Notice: This document has been prepared to assist IEEE It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the Working Group of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE Working Group. If you have questions, contact the IEEE Patent Committee Administrator at C. Wright, Azimuth Systems C. Wright, Azimuth Systems

2 May 2005 doc.: IEEE /378r3 May 2005 Abstract This is a summary of progress within TGT. It closes with a call to action, a discussion of milestones and schedule C. Wright, Azimuth Systems C. Wright, Azimuth Systems

3 Current Status Created draft 0.1 of our output document!
May 2005 Current Status Created draft 0.1 of our output document! Available on web site in members area Contains some definitions that have had substantial discussion Approved guidelines document in Atlanta meeting 11-04/1553r3 Discussed document structure several times Most recent is 11-05/296r0 Developed a test template document Most recent is 11-04/1540r1 C. Wright, Azimuth Systems

4 What else have we done? Discussed a framework for methodology
May 2005 What else have we done? Discussed a framework for methodology Most recent: 11-05/177r0 Discussed various metrics See list in later slide Lots and lots of discussion about test environments Far too much discussion on definitions! C. Wright, Azimuth Systems

5 May 2005 What affects wireless performance? Have we discussed metrics for all these effects? Are there other effects we should be quantifying? C. Wright, Azimuth Systems

6 Presentations that have discussed metrics relevant to TGT
May 2005 Presentations that have discussed metrics relevant to TGT Layer 2 metrics (11-04/1226r1, 11-05/033r0) Throughput, forwarding rate, loss, latency, jitter, others Rate vs. Range (11-04/1397, 11-05/033r0) Or other link layer parameters vs. range Rate adaptation (11-04/1466r1) BSS transition time (11-04/989r1) AKA “roaming time” Adjacent Channel Interference (11-04/215r0) Diversity (11-05/194r0) RF over-the-air performance (11-04/092r1? 11-04/1402r0?) Need to mention test conditions C. Wright, Azimuth Systems

7 Correlation between Test Environments and the “Real World”
May 2005 Correlation between Test Environments and the “Real World” Lots of discussion on the various possible test environments Isolated, conducted, controlled, over-the-air, “real-world”, etc… Still some disagreement on the various names for these environments There is the desire to correlate among the test environments, but more importantly, between the test environments and the “real world” This would seem to have a lot to do with measurements with appropriate channel models C. Wright, Azimuth Systems

8 Correlation with Application Performance
May 2005 Correlation with Application Performance Interactive voice application (frame latency sensitive) We’ve seen several presentations discussing this Do we have agreement on use of E model as voice quality measure that drives wireless metrics? Streaming video application (frame loss sensitive) Have had one presentation on the subject No discussion of an objective quality measure – fertile ground for a literature search Data application (throughput sensitive) What are the measures relevant to a data application? Presumably throughput (goodput; RFC-1242, 2544), anything else? Would be good to have some theoretical backing here Other applications, or other metrics specific to wireless that impact the applications? One possibility: hi velocity trains? Metrics pertaining to security specifically, e.g., If a STA leaves a BSS, how fast does the AP rekey? Measurement of how cryptographically secure random numbers being used are? C. Wright, Azimuth Systems

9 Call to Action We need further development of the metrics
May 2005 Call to Action We need further development of the metrics Let’s have proposals that describe the test methodology with the proposer giving the environment that is needed Further discussion will tell whether other test environments are pertinant or important I would like to get volunteers to “own” various metrics Please write a proposal! Two on the call stated intents to do so C. Wright, Azimuth Systems

10 TGT Standards Process Milestones
May 2005 TGT Standards Process Milestones has started tracking process milestones on the web site These are the dates I’ve estimated for TGT I believe these are highly optimistic We are here 2005 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 1st LB 1st Recirc 1st SB 2006 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec WG/SEC approval REVCOM approval SB Recirc Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 2007 C. Wright, Azimuth Systems

11 Historical 802.11 Task Group Timelines
May 2005 Historical Task Group Timelines Time from PAR approval to first Letter Ballot – average of 6.6 meetings / 13 months TGe-7, TGf-7, TGg-9, TGh-4, TGi-6 Time from first Letter Ballot to first Sponsor Ballot – average of 9 meetings / 18 months TGe-12, TGf-9, TGg-6, TGh-8, TGi-10 (above data compiled by Bruce Kraemer) (slide taken from 11-05/366r0 – TGs) C. Wright, Azimuth Systems

12 TGT process in comparison to average
May 2005 TGT process in comparison to average We’re way behind the average on the first letter ballot We have a draft, but it has no real content The timeline would appear to be optimistic for the time between 1st Letter Ballot and Sponsor Ballot The average would put SB at ~ June 2007 Completion perhaps pushed out to about mid 2008… Eastlake’s Observation: “Things will usually happen slower than what we aim for.” C. Wright, Azimuth Systems

13 Proposed schedule for a January 2006 LB
May 2005 doc.: IEEE /378r3 May 2005 Proposed schedule for a January 2006 LB May 2005 (Cairns, Australia) Presentation of first formal proposals July 2005 (San Francisco, California) More presentation of formal proposals September 2005 (Orange County, California) November 2005 (Vancouver, British Columbia) Review of draft January 2006 (Waikoloa, Hawaii) Letter Ballot authorized by WG March 2006 (New Orleans, Louisiana) Comment resolution May 2006 (TBD) First LB recirculation July 2006 (San Diego, California) Comment resolution… etc. C. Wright, Azimuth Systems C. Wright, Azimuth Systems

14 Comments? We have a bit of work ahead of us! May 2005
