In this paper, we describe the results of a measurement campaign in Ultra-Wide Bandwidth (UWB) indoor channel and specifically this investigation is carried out in a typical open office environment. We have sounded the channel in the time domain, with a probing signal at a carrier frequency of 4.5 GHz modulated by a train of Gaussian monocycle pulses having a 1.25 GHz bandwidth shaped by a pseudonoise (PN) sequence. To analyze the channel behavior over the large (i.e. path-loss), mid (i.e. shadowing) and small (i.e. multipath) scale, the position of the transmitter has been kept fixed and different measurements have been taken with the receiver situated on a set of concentric circles around the transmitter. Moreover, for each position on a circle, the receiver locations are arranged in a square grid of 6×6 points with 14 cm spacing. We describe the measurement technique and then process the experimental data to extract the fading statistics for the UWB indoor channel
