Comparison for geometry
 
Line of Sight  (Bounce = 1)
While double the room size, energy from 1 bounce drops 85% (95 to 14)
Remark:
 Size of room geometry can affect received optical power
Diffuse (Bounce > 1)
While double the room size, energy from diffuse drops 52% (46 to 22)
Remark: 
Application employ diffuse links are less sensitive to geometry change.

Conclusions
 
Different geometry setup will affect optical signal.
Diffuse link are more robust compared with direct link.
