工信部:5G发展进入第二阶段 近期将发布测试最新成果
央广网北京9月7日消息(记者张棉棉)据中国之声《全国新闻联播》报道,工信部信息通信发展司司长闻库今天(7日)在2017中国国际信息通信展览会新闻发布会上表示,第五代移动通讯技术(5G)发展进入第二阶段,目前研发和测试进展良好,有些指标好于预期,近期将发布第二阶段测试的最新成果,并公布5G后续安排。
第五代移动通讯技术(5G)经过去年关键技术方案验证以及系统方案验证,已证明5G概念在技术上可行。工信部信息通信发展司司长闻库表示,今年已经进入5G发展第二阶段,比较系统的开展实验。“主要把去年验证的一些技术,今年把它集成一个系统,而且随着技术的开发,标准同时也在世界上不断推进,有些标准也在逐渐成熟,比如大规模天线、编码,今年就把它作为一个系统级的技术。”
5G面向物联网主要包括三个场景,能达到千兆速率的增强移动带宽,高可靠、低时延的毫秒级通信控制,以及“大连接”,目前,这三个场景的研发和测试都进展良好,有的甚至比预期还要好。峰值速率、时延、移动性方面进展良好,有的指标比开始阶段设计的指标还好,这次通信展可以说是5G应用爆发前的集中展示,因为这个标准到明年固定,目前为止一些技术已经完成。
闻库透露,目前4G用户已经达到9.1亿户,占移动电话用户的比重达到66.3%,三大运营商都有向5G转型的战略,9月27至30日举行2017中国国际信息通信展览会期间,除了分享5G技术、应用标准、研究成果,探讨未来的发展之外,或将颁发5G第二阶段的测试证书,并发布5G后续安排。
