Abstract :
We report on ultra-wideband (UWB) indoor channel measurements we have performed for several scenarios in an office building. Results are presented regarding the multipath decay supporting the applicability of the widely assumed exponential decay in a single cluster case, and show some results for a two-cluster situation caused by in-building back reflection. The frequency dependent decay of the channel gain with increasing frequencies is discussed in some detail regarding the competition between a power and a polynomial law. We present a power law for received power versus distance in a corridor environment and finally suggest some modifications allowing to adapt well known propagation model elements.
