5G高频应用场景研究

Research on 5G high frequency applications

传统的移动通信技术主要使用低频和中频频段,而5G技术引入了更高的频段,包括毫米波频段。高频频段具有更高的带宽和更快的传输速度,可以支持更多的设备连接和更大的数据传输量,相应地也存在覆盖范围小和传输距离受限等缺点。本文从高频信号传输特性入手,运用5G新技术和新功能,探索5G高频在无线接入、物联网连接、FWA、无线回传、虚拟和增强现实等实际中的应用。

While traditional mobile communications use low-and intermediate-frequency bands,5G technology has introduced higher frequency bands,including the millimeter wave band,which has higher bandwidth and faster transmission speeds,it can support more device connections and larger data transmission volume,and correspondingly has some disadvantages such as small coverage,limited transmission distance and so on.This paper starts with the transmission characteristics of high-frequency signals,uses new 5G technologies and functions,and combines the SLA service requirements for wireless network stability,performance,and reliability to explore the application of 5G high-frequency in wireless access,IoT connection,FWA,and wireless backhaul.
