60 GHz车载可穿戴部署天线的路径损耗特性
Path Loss Characterization for Intra-Vehicle Wearable Deployments at 60 GHz
摘要：
在这项工作中，我们提出了一个宽带测量活动在60 GHz的Linkker电动城市巴士内进行的结果。针对未来毫米波（mmWave）公共交通可穿戴场景，我们模拟了密集环境中移动高端消费设备的典型部署。具体而言，我们的车内部署包括一个接收器和多个发射器，对应于毫米波接入点和乘客的可穿戴和手持设备。当接收器位于公共汽车的前部时，发射器重复个人设备（i）在座位水平处的实际位置（例如，手持设备）和（ii）在座位上方70厘米的高度（例如，可穿戴设备：增强现实眼镜或盔装显示器）。基于测量的接收功率，我们构建了一个对数模型的距离相关的路径损耗。在这项研究的过程中开发的参数化模型有可能成为一个有吸引力的地面在拥挤的公共交通场景的链路预算估计和干扰足迹的研究。
英文摘要：
In this work, we present the results of a wideband measurement campaign at 60 GHz conducted inside a Linkker electric city bus. Targeting prospective millimeter-wave (mmWave) public transportation wearable scenarios, we mimic a typical deployment of mobile high-end consumer devices in a dense environment. Specifically, our intra-vehicle deployment includes one receiver and multiple transmitters corresponding to a mmWave access point and passengers' wearable and hand-held devices. While the receiver is located in the front part of the bus, the transmitters repeat realistic locations of personal devices (i) at the seat level (e.g., a hand-held device) and (ii) at a height 70 cm above the seat (e.g., a wearable device: augmented reality glasses or a head-mounted display). Based on the measured received power, we construct a logarithmic model for the distance-dependent path loss. The parametrized models developed in the course of this study have the potential to become an attractive ground for the link budget estimation and interference footprint studies in crowded public transportation scenarios.
