Abstract
In this paper, based on a set of Ultra Wide Bandwidth Channel (UWB) measurements the dependance between Path Loss and frequency is investigated. The measurements are provided in frequency domain over a channel bandwidth 6 GHz (from 3 to 9 GHz) in different locations. 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 (Tx) and receiver (Rx) 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, but the path loss and central frequency present a correlation.
