5. doc.: IEEE 15-06-0254-00-003c Submission May 2006 Su-Khiong Yong, Samsung-SAITSlide 5 Classifications of Environment (2) Residential –Typical home with multiple rooms and furnished with furniture, TV sets, lounges, etc. The size is comparable to the small office room. The walls/floor are made of concrete or wood covered by wallpaper/carpet. There are also windows and wooden door in different rooms within the residential environment.

6. doc.: IEEE 15-06-0254-00-003c Submission May 2006 Su-Khiong Yong, Samsung-SAITSlide 6 Classifications of Environment (3) Desktop –Typical office desktop and computer clutter. Partitionings surrounded this environment Conference Room –Typical conference room with metal shelves, white board and office window. Corridor –Passage way that links different offices. Library –Typical small size library with multiple desks, chairs and metal bookshelves. Bookshelves are filled with books, magazines, etc. Some tables and chairs were interspersed between the bookshelves. At least one side of room has windows and/or door. The walls are made of concrete.

10. doc.: IEEE 15-06-0254-00-003c Submission May 2006 Su-Khiong Yong, Samsung-SAITSlide 10 Classifications of Environment Office –Typical office setup furnished with multiple chairs, desks, computers and work stations. Bookshelves, cupboards and whiteboards are also interspersed within the environment. The walls are made by metal or concrete covered by plasterboard or carpet with windows and door on at least one side of the office. –Cubical, laboratory, open and closed office can be treated as a generic office. Typically these offices are linked by long corridors. FT treats closed-office, corridor and conference room under the umbrella of typical office

11. doc.: IEEE 15-06-0254-00-003c Submission May 2006 Su-Khiong Yong, Samsung-SAITSlide 11 General Considerations Some cases have 4 sources and how does the group should “down select” for each environment? Options 1.Selection based on merits of the measurement capabilities given in the next table. 2.Selection based on the worse case result. 3.Selection by averaging the available results. Note: Options 2 and 3 are can be unrealistic as –Different measurement setups especially Tx and Rx antennas used are of different gains. –Environment details are quite different even can be classified under the same umbrella.

15. doc.: IEEE 15-06-0254-00-003c Submission May 2006 Su-Khiong Yong, Samsung-SAITSlide 15 Conclusion To have a realistic number of channel models for performance evaluation, “down select” must be taken. Selection is based on the various figure of merits such as measurement capability and flexibility Unselected channel models will serve as a reference.
