Abstract :
In the present paper an alternative method of analysis is proposed to extract reflection and transmission properties of arbitrary wall-like objects from wideband measurements of radio channels in the GHz-range. Mean effective reflection and transmission factors are derived depending on the frequency of the electromagnetic waves, polarization and incidence angle on the surface of the object. Working with ratios of quantities most systematic errors are compensated for automatically which can be seen as an advantage of this method. By classifying different wall-types the derived reflection and transmission coefficients can be used in look-up tables to improve the prediction quality of ray-tracing models, especially for very inhomogeneous environments e.g. indoor areas
