1 IEEE P802.15 Working Group for Wireless Personal Area Networks
November 1999 IEEE P Working Group for Wireless Personal Area Networks Coexistence Study Group Report #2 Hyatt Regency Kauai, HI Steve Shellhammer, Symbol Technologies

2 Plan for the week Coexistence SG update to ExCom
November 1999 Plan for the week Coexistence SG update to ExCom New Coexistence SG web site Call for Submissions on Coexistence Model David Cypher & Nada Golmie Coexistence, Interoperability, & Other terms MAC Performance Evaluations Kevin Marquess PHY Model Open Questions ExCom vote on PAR, Thursday night Steve Shellhammer, Symbol Technologies

3 References Coexistence Charter 802.15-99/088r2 PAR 802.15-99/086r3
November 1999 References Coexistence Charter /088r2 PAR /086r3 Five Criteria /096r1 Coexistence Study Group Web Site Steve Shellhammer, Symbol Technologies

4 Need for Coexistence Task Group
November 1999 Need for Coexistence Task Group It is important that IEEE WPAN devices coexist with other wireless devices in the unlicensed frequency bands. In particular it is very important that WPAN devices coexist with IEEE WLAN devices. Steve Shellhammer, Symbol Technologies

5 Scope of Coexistence Task Group
November 1999 Scope of Coexistence Task Group The goal will be to address coexistence of: Any WPAN with any WLAN Any WPAN with any other WPAN (assuming there will be more than one) Any WPAN with selected other devices in the same band (e.g. HomeRF). Steve Shellhammer, Symbol Technologies

6 Coexistence Task Group Charter
November 1999 Coexistence Task Group Charter Develop a Coexistence Model for the GHz ISM band, that we can all agree to, which will help us assess the issues of Coexistence in a more quantitative way Deliver a Recommended Practice for WPAN and WLAN devices intended to coexist in a common environment. Steve Shellhammer, Symbol Technologies

7 Coexistence Model The purpose of this model is:
November 1999 Coexistence Model The purpose of this model is: To understand under what circumstance there is a coexistence problem and under what circumstances there is not a problem. To develop supporting evidence to justify the recommended suggested practices Steve Shellhammer, Symbol Technologies

8 Coexistence Model PHY Layer Models Data Traffic Models
November 1999 Coexistence Model PHY Layer Models MAC Layer Models Data Traffic Models Coexistence Model RF Propagation Models Steve Shellhammer, Symbol Technologies

9 How can 802.11 & 802.15 Collaborate on the issue of Coexistence?
November 1999 How can & Collaborate on the issue of Coexistence? We put together a proposal by talking to personnel within and We discussed the proposal Tuesday within the Study Group We then voted on the proposal in the Study Group Steve Shellhammer, Symbol Technologies

10 Proposal for Task Group Operation
<month year> doc.: IEEE <doc#> November 1999 Proposal for Task Group Operation The Coexistence Study Group would become a Task Group in The Liaisons from would be able to vote in the Task Group since they have voting rights in Progress of the group would be reported at the regularly scheduled / joint sessions Steve Shellhammer, Symbol Technologies <author>, <company>

11 Proposal for Task Group Operation
November 1999 Proposal for Task Group Operation Once a draft Recommended Practice is ready for letter ballot it would be submitted to both the and the Working Groups for separate letter ballots. In order for the Recommended Practice to be forwarded to the Executive Committee for Sponsor ballot, the letter ballot must pass in both Working Groups. Steve Shellhammer, Symbol Technologies

12 Proposal for Task Group Operation
November 1999 Proposal for Task Group Operation Anyone attending a Coexistence Task group session would be given attendance credit, for that time, in either or Steve Shellhammer, Symbol Technologies

13 November 1999 Study Group & Votes Vote to recommend to ExCom that the SG become a Task Group in and recommend the proposed voting scheme Yes: 21 No: 4 Abstain: 9 (SG) Yes: 19 No: 0 Abstain: 9 (dot 11) Should the SG become a TAG Yes: 3 No: 21 Abstain: 11 (SG) Yes: 0 No: 16 Abstain: 7 (dot 11) Vote to recommend the attendance credit procedure to & Yes: 31 No: 0 Abstain: 7 (SG) Yes: 25 No: 0 Abstain: 6 (dot 11) Steve Shellhammer, Symbol Technologies

14 Motion of Proposed Voting Rules
November 1999 Motion of Proposed Voting Rules Motion to approve the separation of the subsequent letter ballot output from the coexistence Task Group to both and voting members and for both groups to agree before sending to Excom Yes: 21 No: 0 Abstain: 0 (.11) Yes: 14 No: 0 Abstain: 0 (.15) Steve Shellhammer, Symbol Technologies
