Many features of 5G are definitely important to the broadcasting service, including diverse content services such as follow-me TV, video-on-demand, but also gaming, Virtual reality (VR) and Augmented reality (AR) and many others. Meanwhile, those services depend more and more on the user’s position accuracy, especially in indoor environment. With the increase of broadcasting data traffic indoors, to obtain a highly accurate position is becoming a challenge because of the impact of radio interference. In order to support a high-quality indoor broadcasting service, a high-accuracy positioning, radiation-free, and high-capacity communication system is urgently needed. In this paper, a 5G indoor positioning system is proposed for museums. It utilizes unlicensed visible light of the electromagnetic spectrum to provide museum visitors with high-accuracy positioning, multiple forms of interaction services, and high-resolution multimedia delivery on a mobile device. The geographic data and the location-related data integrated into the 5G New Radio (NR) waveform are detailed. A general-purpose system architecture is provided and some basic techniques to enhance system performance are also investigated. A preliminary demonstration is built in the laboratory environment. It supports over 45.25 Mbps data rate and a mean positioning error of 0.18 m.

用于室内广播服务的5G无线电光定位系统互联网

5G 的许多功能对于广播服务绝对重要，包括各种内容服务，例如跟我来电视、视频点播、游戏、虚拟现实 (VR) 和增强现实 (AR) 等。同时，这些服务越来越依赖于用户的位置精度，尤其是在室内环境中。随着室内广播数据流量的增加，由于无线电干扰的影响，获得高度准确的位置正成为一项挑战。为了支持高质量的室内广播业务，迫切需要一种高精度定位、无辐射、大容量的通信系统。本文提出了一种面向博物馆的5G室内定位系统。它利用未经许可的电磁频谱可见光，在移动设备上为博物馆参观者提供高精度定位、多种形式的交互服务和高分辨率多媒体传输。地理数据和位置相关数据集成到 5G 新空口 (NR) 波形中进行了详细说明。提供了一个通用系统架构，并研究了一些增强系统性能的基本技术。在实验室环境中进行了初步演示。它支持超过 45.25 Mbps 的数据速率和 0.18 m 的平均定位误差。提供了一个通用系统架构，并研究了一些增强系统性能的基本技术。在实验室环境中进行了初步演示。它支持超过 45.25 Mbps 的数据速率和 0.18 m 的平均定位误差。提供了通用系统架构，并研究了一些增强系统性能的基本技术。在实验室环境中进行了初步演示。它支持超过 45.25 Mbps 的数据速率和 0.18 m 的平均定位误差。
