Propagation
of electromagnetic waves inside buildings in the
frequency range above 600 MHz is influenced mainly by
the walls (and large furniture elements). Therefore a
detailed vector database of the buildings is required.
For frequencies below 600 MHz, only empirical
propagation models should be used.
Typically the
multipath propagation is very important in indoor
environments. Simple empirical propagation models are
therefore not sufficient.
The indoor propagation models can be used for cellular
network planning (picocells) as well as for LOS
analysis.
If the penetration of electromagnetic waves into
buildings ("indoor coverage") must be analyzed or if the
radiation from transmitters inside buildings to the
outdoor world is important, the WinProp's combined
network planning approach (CNP) should be used. |
This is a typical indoor propagation environment with
some propagation paths.

Phenomena
like multi-path propagation, reflection, diffraction and
shadowing have a significant influence on the received
power. So the propagation models should consider these
phenomena to obtain accurate results.
WinProp offers a wide variety of propagation models for
indoor scenarios.
