Nov 2006 Channel Model Scenario Environment Descriptions CM1 LOS 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. CM2 NLOS CM3 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. CM4 CM5 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. CM6 CM7 Conference Room Typical conference room with metal shelves, white board and office window. CM8 CM9 Desktop Typical office desktop and computer clutter. Partitioning surrounded this environment CM10 Corridor Passage way that links different offices Su-Khiong Yong, Samsung-SAIT

Nov 2006 Resolved Issues in TG3c Channel Modeling Sub-committee Final Report (06/195r4) Dealing with circular polarized model. Change environment conference room LOS (CM7) and NLOS (CM8) to office (LOS ONLY, CM7) and residential (LOS ONLY, CM8) Effects of antenna de-convolution in 398r3? Is the channel model antenna specific? Matlab Code is not yet available. How long we can wait? Shall not consider circular polarized model Effects of antenna de-convolve for all other channels except circular polarized All RX antennas were de-convolved but NOT the TX n in the LOS office (CM3 and CM4) does not match to the PL n n used in CM3 and CM4 was derived based on small set of data to reflect  value for small scale usage. Stay as it is Fix h, height of the antenna and d, distance of the antenna? Not fixed but uniformly distributed as described in CM9 Su-Khiong Yong, Samsung-SAIT

Unresolved Issues – Matlab Code Nov 2006 Unresolved Issues – Matlab Code CM1, CM3 and CM9 have multiple representations. How to deal? Stay as it is. Matlab Code is not yet completely finalized due to New contribution in 478r0 for CM4 Rick will provide an update on the code Validation of the simulated channel by measurement results. How to deal with the improvement of the amplitude statistics, 06/4530? Channel becomes “semi-statistical” To be considered in the selection criteria document 05/493r22 How to integrate Matlab Packages discussed 0459r1 and 0468r0 and what is the timeline? Target to complete within one month time frame after the Dallas Meeting Distribution of the Matlab Package. Distribute in terms mat file, Excel sheet and/or Matlab functions? Yes Su-Khiong Yong, Samsung-SAIT
