Description of Short-range LOS
Usage Model
Use cases
Application mix
Comments
Short range LOS
U3, U4, U5, U6, U7, U8, U9, U12, U13, U16, U17
P-MP and P-P
Usage model limited for LOS and Short Range 　(< 5 m)
To be evaluated at PHY-SAP
Application mix is not important because performance should be evaluated at the PHY-SAP.
Due to the TX power limitation, transmission distance is basically short. Then most of practical use cases including file transfer, video streaming, mobile gaming and ad-hoc meeting can be covered by this usage model.

Conclusion
Short-range LOS applications are suggested.
They include file transfer, video streaming, mobile gaming and wireless ad-hoc meeting.
We should notice that transmission distance is basically short due to the TX power limitation.
