摘要

本文介绍了用于医疗保健应用的2.48 GHz静态体上信道的实验特性。测量是在消声室和实验室进行的。链路质量可以通过使用矢量网络分析仪来测量，其中路径损耗在一段时间内平均，或者从接收信号强度指示器(RSSI)计算，这可以从接收传感器模块计算。路径损耗和包传输比(PDR)之间的相关性将通过给定发射功率的RSSI的概率分布来实现。此外，还可以获得不同位置的最佳发射功率，这将有助于节省电池能量。

Experimental correlation of path loss with system performance in WBAN for healthcare applications

This paper presents the experimental characterization of the static on-body channel for healthcare applications at 2.48 GHz. The measurements are conducted in the anechoic chamber and laboratory. The link quality is measured by either using a vector network analyzer, where the path loss is averaged over a period of time or calculated from the received signal strength indicator (RSSI), which can be calculated from the receive sensor module. A correlation between the path loss and the packet delivery ratio (PDR) will be made via the probability distribution of the RSSI for a given transmit power. In addition, the optimal transmit power at the different body locations can be obtained, which will be useful to conserve the battery energy.
