无线体域网（WBAN）有望成为医院和家庭护理、远程医疗和身体康复等医疗保健领域的突破性技术。由于人体具有由不同组织组成的复杂形状，因此预计在WBAN的情况下电磁信号的传播的性质与在其他环境中发现的电磁信号的传播的性质非常不同，例如办公室、街道等。先前已经有几项实验研究旨在表征WBAN情况下的超宽带（UWB）信道的性质。在本文中，我们描述了我们的贡献，以扩大知识的UWB信道在3-11 GHz的频率范围内的实际情况下，预计将在医疗应用中发现的测量。我们还提出了通道模型，已开发使用的实验结果。
Wireless body area networks (WBAN) are expected to be a breakthrough technology in healthcare areas such as hospital and home care, telemedicine, and physical rehabilitation. Because the human body has a complex shape consisting of different tissues it is expected that the nature of the propagation of electromagnetic signals in the case of WBAN to be very different than the one found in other environments, e.g. offices, streets, etc. There have been several previous experimental studies aimed to characterize the nature of the UltraWideband (UWB) channel for the case of WBANs. In this paper we describe our contribution to expand the knowledge of the UWB channel by taking measurements in the frequency range of 3-11 GHz in realistic scenarios expected to be found in medical applications. We also present channel models that have been developed using the experimental results.
