5. Classifications of Environment
May 2006
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

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.

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.

For IBM data, currently still unable to distinguish between LOS or NLOS
UMASS measurement still on going

Motion
The TG3c Channel Modeling Subgroup will consider only the following six environments: Office, Residential, Desktop, Conference Room, Corridor and Library as defined in the document c. Motion by A. Mathew, seconded by T. Pollock

10. General Considerations
May 2006
General Considerations
Some cases have 4 sources and how does the group should “down select” for each environment?
Options
Selection based on merits of the measurement capabilities given in the next table.
Selection based on the worse case result.
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.

Proposed Set of Channel Models
Residential – LOS (CM1) and NLOS (CM2)
Office – LOS (CM3) and NLOS (CM4)
Library – LOS (CM5) and NLOS (CM6)
Conference Room – LOS (CM7), NLOS (CM8)
Desktop – LOS (CM9)
Additional sets of above models with different antenna gains

Future Plan
Expected timeline for all data analysis MUST be done by one week prior to the San Diego’s Meeting i.e.
Final Report Drafting
Matlab Code Generation

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.
