摘要:

由于成本、尺寸和重量的降低,\acp{UAV}在通用民用和商业应用中变得越来越流行。通过使用现成的陆地蜂窝部署向\acp{UAV}提供用于用户数据和控制消息收发的通信服务引入了若干技术挑战。在本文中,空-地信道特性的低高度\acp{UAV}的基础上广泛的测量活动的方法,提出了特别注意的结果比较时,一个典型的定向天线网络部署时,被认为是一个准全向。信道特性,如路径损耗,阴影衰落,均方根延迟和多普勒扩频和K因子的统计特征为不同的郊区的情况。

英文摘要:

Due to the decrease in cost, size and weight, \acp{UAV} are becoming more and more popular for general-purpose civil and commercial applications. Provision of communication services to \acp{UAV} both for user data and control messaging by using off-the-shelf terrestrial cellular deployments introduces several technical challenges. In this paper, an approach to the air-to-ground channel characterization for low-height \acp{UAV} based on an extensive measurement campaign is proposed, giving special attention to the comparison of the results when a typical directional antenna for network deployments is used and when a quasi-omnidirectional one is considered. Channel characteristics like path loss, shadow fading, root mean square delay and Doppler frequency spreads and the K-factor are statistically characterized for different suburban scenarios.
