Effects of Buildings - inside

• Coverage defined by geometry of building

• Small changes in environment have large influence on propagation

• Propagation characteristics:

  • reflection and diffraction from objects
  • loss through walls and floors
    • frequency re-use?
  • channelling of energy

• Characteristics of indoor propagation differ from those of outdoor:
  • signal coverage governed by well-defined geometry
  • features in propagation path have large influence on signal propagation

• Reflection and diffraction around objects, including walls and floors

• Loss through walls, floors and objects
  • floor loss important in considerations of frequency reuse between floors of the same building

• Channelling of energy, especially in corridors at high frequencies.
