Ultra wide bandwidth radio channel indoor propagation and path loss analysis based on measurements

In this paper, based on a set of UWB Channel measurements some features of channel are investigated. The measurements are provided in frequency domain over a channel bandwidth 6 GHz (from 3 to 9 GHz) in indoor, at Eurecom Institute. A vector network analyzer is used to measure the frequency channel response of the frequency bandwidth of interest. An omni-directional antennas are used for both the transmitter and receiver antennas. Probability Density Function (PDF) and Cumulative Distribution Function (CDF) of received signal, power variation and path loss fluctuations are evaluated in frequency domain. An investigation of path loss shows no dependency between frequency and the path loss. Other features of this approach also are outlined.
