Description of Short-range LOS July 2006 Description of Short-range LOS Usage Model Use cases Environments Application mix Comments Short range LOS U3, U4, U5, U6, U7, U8, U9, U12, U13, U16, U17 Residential, Office 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. NiCT, NTT

Description of gigabit ethernet July 2006 Description of gigabit ethernet Usage Model Use cases Environments Application mix Comments Gigabit Ethernet U17 Desktop, Office 5 PCs and 1 printer PCs and printer are basically located in line-of-sight (LOS) from an access point. NiCT, NTT

Conclusion Short-range LOS applications are suggested. July 2006 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. NiCT, NTT
