In this paper, we expand the knowledge of the ultra-wideband (UWB) channel in the frequency range of 3.1–10 GHz in close proximity of a human body. The channels under dynamic conditions due to the effect of body motions are studied through the pseudo-dynamic measurement method. Firstly, the first-order statistics of the channels, namely, amplitude distributions are investigated. Secondly, the dynamic features of the channels are also studied through the second-order statistics of the channels, namely, the good and bad channel durations as well as the LCR, which are important for a cross-layer design. Three strongest peaks capturing most of the energy of the channel are taken into account. Finally, a two-state alternating Weibull renewal process model is proposed. The model provides good usability with low complexity and can then be used to better design communication network protocols for WBANs. In addition, for the sake of designing a non-coherent receiver, the dynamic delay spread of the channel, which determines an energy collector detecting the signal energy over a time window, is investigated.
