2. September 2006 Bruce Bosco, MotorolaSlide 2 doc.: IEEE 802.15-06-0399-01-003c Submission Usage Model Document: Inputs For Final Draft UM1 Comment regarding LOS/NLOS and data rates: Integrated systems will most certainly be NLOS in many/most cases. Propose 1080p performance will be required for this scenario as well - that is 2.986 Gbps raw. Comment regarding data rate: Does this preclude the use of TMDS? Comment regarding range: Propose LOS  10m; NLOS  5m for both mandatory and optional cases. Recommendation: –Change U1 to LOS/NLOS –Change Environment to LOS/NLOS both cases –Change range: 5m/10m both cases

3. September 2006 Bruce Bosco, MotorolaSlide 3 doc.: IEEE 802.15-06-0399-01-003c Submission UM4: Comment: Ad-hoc network can be LOS or NLOS. Unless everyone is sitting at a large conference table and even then could be objects blocking direct path. Recommendation: –Change U16 to reflect LOS/NLOS –Change Environment to LOS/NLOS Desktop

4. September 2006 Bruce Bosco, MotorolaSlide 4 doc.: IEEE 802.15-06-0399-01-003c Submission UM5 Comment: Portable units can be handheld. Note: Simulations might be done by perturbation of AOA and/or range, to very approximately replicate jitter. For example (representative numbers): +/- 1.0  AOA, +/-.01m range. May be more accurate ways of simulating as well. Could be left up to proposer to specify. Comment: May be issue with initial alignment of antenna but that probably will be an issue unless there is a docking station of sorts. Comment: UM5 should include peer-to-peer networking option. Comment: The download could be symmetric or perhaps symmetric/non- symmetric. For example, downloading or sharing high resolution photos for printing. Or downloading or sharing high definition video or other multimedia content. Recommendation: –Change U7 and U9 to reflect fixed OR handheld and include peer-to- peer networking options. –Show peer-to-peer option in UM5 –Change non-symmetric to either symmetric or symmetric/non-symmetric
