Abstract

An experimental characterization of the off-body propagation channel for the ultrawideband (UWB) band from 3.1 GHz to 8 GHz for body area networks (BAN) is presented in this letter. The channel is evaluated in terms of path loss (PL) and Root Mean Square (RMS) delay spread. Channel statistics from measurements carried out considering subjects of different gender in standing still position under line-of-sight (LOS) conditions are compared to the ones without the presence of the body to evaluate the variation on the statistics of the channel in presence of a human body. It is observed a high variation on the path loss and the RMS delay spread parameters for the same attachment position of the receiver antenna on the body of the subjects and a dependence of the statistics with the number of received multipath components (MPC) because of the shadowing effect of the body.
