摘要
随着基于位置服务的广泛普及,用户对于高精度室内定位的需求与日俱增,但目前常用的GPS、北斗等卫星导航系统由于信号衰减等因素无法直接应用在室内环境,而基于Wi-Fi、蓝牙等技术的定位方法面临着精度低、成本高的不足。针对这些问题,本文通过分析现有无线定位方法,结合未来5G通信架构的发展趋势,提出一种带内高精度定位网系统架构,并针对该架构下同步、首径信号检测等关键技术进行阐述,实现通信网与定位网平滑融合。
With the widespread popularity of location based service, users＇ demand for high precision indoor positioning is growing. However, GPS and COMPASS satellite navigation system cannot be directly applied in the indoor environment due to signal attenuation. The localization method based on Wi-Fi and Bluetooth technology is faced with the problem of low accuracy and high cost. In this paper, we analyze the existing wireless positioning method. Combining the development trend of the future 5G communication architecture, an inband high precision positioning system architecture is proposed. The key technologies of synchronization and first-path signal detection are introduced to achieve the integration of communication network and positioning mesh smoothly.
