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.
