1. Usage Model Document: Recommended Amendments for Final Draft
The purpose of this document is to provide recommended revisions and clarification for Use Cases and corresponding Use Models.

2. Usage Model Document: Inputs For Final Draft
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 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. 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 Desktop

4. 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
