【答案】5G是数据传输速率更快,网络延迟较低,具有连接千亿设备能力的最新一代蜂窝移动通信技术。【解析】【详解】本题考查学生下定义能力。“下定义”必须抓住被定义事物的基本属性和本质特征,例如:多采用判断单句的形式。其格式多为“×××(种概念)是×××的×××(属概念)”。本题根据下定义的格式,本题为“5G是……的最新一代蜂窝移动通信技术”。找到句子主干后,然后把修饰内容按照一定的逻辑顺序放入主干内。“5G网络的主要优势在于,数据传输速率远远高于以前的蜂窝网络,最高可达10Gbis,比当前的有线互联网要快,比先前的4GLTE蜂窝网络快100倍”概括出“数据传输速率更快”,“另一个优点是较低的网络延迟(更快的响应时间),低于1毫秒,而4G为30-70毫秒”概括出“网络延迟较低”,“5G有超大网络容量,具有连接千亿设备的能力,能满足物联网通信”概括出“具有连接千亿设备能力”。把5G“数据传输速率更快”“网络延迟较低”“具有连接千亿设备能力(能连接千亿设备)”这几个特点作为限定修饰语依次填到“5G是……的最新一代蜂窝移动通信技术”句中即可。
