摘要
5G是第五代移动网络,是在4G之后发展的下一代移动网络,其特点是具有更高的频谱效率,可以为更多用户提供服务,而且提供的数据质量更加高效,并可以提供更稳定的用户体验。近些年,基于5G通信技术的物联网发展迅猛,设备连接数量不断增加,5G通信网络将会支持更高的设备连接密度。5G与之前的移动通信技术不同,它是针对现有架构的一种演进和重新构思,以便可以从当前和将来的基础结构中获得最大的灵活性和运营效率。介绍分析5G技术的8大关键性指标、5G产业链中所涉及到的移动通信基础设施、移动通信运营商服务、终端及应用场景等方面,最后还介绍了5G的3大类应用情景,分别是增强型移动宽带(enhanced Mobile Broad Band,eMBB)、超高可靠与低延迟的通信(ultra-Reliable and Low Latency Communications,uRLLC)以及大规模机器通信(massive Machine Type Communications,mMTC)。
5G is the fifth generation mobile network,the next generation mobile network developed after 4G.It is characterized by higher spectrum efficiency,can provide services to more users,and provides more efficient data quality,and can provide more stable user experience.In recent years,the Internet of Things based on 5G communication technology has developed rapidly and the number of device connections has been increasing.5G communication networks will support higher device connection density.Unlike previous mobile communications technologies,5G is an evolution and reimagining of existing architectures in order to maximize flexibility and operational efficiency from current and future infrastructures.This paper introduces and analyzes the eight key indicators of 5G technology,mobile communication infrastructure,mobile communication operator services,terminals and application scenarios involved in the 5G industry chain,and finally introduces three categories of 5G application scenarios,namely enhanced Mobile Broad Band(EMBB),ultra-Reliable and Low Latency Communications(uRLLC),and Massive Machine Type Communications(MMTC).
