doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 2 Status Meetings –Minutes in r10 –11 meetings, 12 hours telecon, 8.5 hours F2F Output Document – r8 (40 pages) Status of document –“Not quite complete”

doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 3 Usage Model Document Environments – 41 Applications – 25 (4 incomplete) Use Cases – 37 Usage Models – 10 Simulation Scenarios – 8 (2 missing)

doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 4 Example Usage Model (Residential) 1 x AP STA 1: 19.2 Mbps HDTV (A4), VoD control channel (A2) STA 3: 24 Mbps HDTV (A4), VoD control channel (A2) STA 4: SDTV (A3), internet file transfer (A9), Video gaming, controller to internet (A18), local file transfer A(15), printing (A22) STA 5 & 6: Video Phone (A23), internet file transfer (A9) STA 7,8 & 9: VoIP (A9) STA 10: Internet streaming video (7), MP3 Audio (A12), Video gaming, controller to internet (A18), local file transfer A(15) STA 11: Video gaming, controller to console (A16)

doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 5 Simulation Scenario Methodology Parameters for Tx power and Rx noise figure are common to all scenarios One table per device in a scenario, contains: –Name, location, channel model –List of data source descriptions

doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 7 Status / Future Work The document does not yet represent a consensus of the group due to the high rate of changes made in recent weeks Improved alignment with external comments needs to be considered (e.g. effect of WFA MRD) Some Applications have unknown traffic patterns The Simulation Scenarios are incomplete The Simulation Scenarios are largely untested There is no error model defined It may be incomplete with respect to or contradict the functional requirements and selection criteria documents.

doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 8 Recommendation Identify an existing group or form a new group under n with authority to modify and maintain the Usage Models document throughout the lifetime of n 4 Hours of F2F time this meeting (with no competing.11n activities) specifically to address Usage models with the aim of reaching consensus

doc.: IEEE /702r0 Submission September 2003 Adrian Stephens, Intel CorporationSlide 9 Motion Move that TGn form a special committee with responsibility for maintaining and modifying the Usage Model document to be consistent with the Selection Criteria and Functional requirements documents as they are developed, and to resolve issues discovered with the simulation scenarios as they are implemented.
