In a future 4G or WLAN wideband application we can imagine multiple users in a large office environment con-sisting of a single room with partitions. Up to now, indoor radio channel measurement and modelling has mainly concentrated on scenarios with several office rooms and corridors. We present here measurements at 5.8GHz for 100 MHz bandwidth and a novel modelling approach for the wideband radio channel in a large office room envi-ronment. An acoustic like reverberation theory is pro-posed that allows to specify a tapped delay line model just from the room dimensions and an average absorption co-efficient of the delimiting walls. The proposed model agrees amazingly well with the measurements, showing that the diffuse part is uniformly spread over the room with a constant energy level and a constant temporal de-cay slope. Furthermore, we analyze fading statistics and capacities calculated from the measurements. The pro-posed model can likely also be applied to indoor hot spot scenarios.
