Indoor Prediction Models

Predictions Models for Indoor Scenarios

Application

 

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.

Propagation Models

 

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.
