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, WinProp's combined
network planning approach (CNP) should be used.

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.

Databases

For
most indoor planning tools, the handling of the building data is the
most critical part. If the tool is too complicated or if it takes too
much time to define a building database with the tool, it makes no
sense to plan the indoor network with a software tool. If this is your
opinion, you should either install the network without any computer
assistance or you should select a different (better) software product.
We recommend the second option, because you will get high-performance
networks within a few minutes.
