4G已经这么快了 为什么还需要5G? - NetSmell

按照国际电信联盟关于2020年的规划,5年后就要全面进入5G了,而到现在核心技术体系还没有确立。回顾3G技术发展史,国际电信联盟于1998年6月30日接收了3G技术提案,并迎来了第一个驼峰期,直到2009年1月7日,工业和信息化部正式发放了三张3G牌照,这才进入到第二个驼峰,平台期持续了11年,特别是三张牌照之一的TD-SCDMA,直到2013年才真正成熟,平台期长达15年,可刚成熟4G时代就来临了。按照"双驼峰规律",5年后将在全球推广使用的技术,应在2010年左右就迎来第一个驼峰,而不会在2020前的两三年横空出世,然后迅速被国际电信联盟确定为全球的5G标准,这违反了一般的技术发展规律,不太可能成真。
