Summary:
Antenna system and many propagation processes would introduce frequency dependent characteristic within frequency band of UWB signal. This would cause the frequency dependence of path loss. In this paper, a frequency dependent UWB path loss model for NLOS environment is proposed base on the analysis of the Intel experimental data. The proposed model can model the frequency dependence caused by antenna system and propagation processes separately by introducing frequency dependent path loss exponent in traditional model. The fitting of the experimental data shows that the path loss exponent can be modelled as Gaussian function when taking into account its changes with frequency.
