长期演进技术英语:LTE,Long Term Evolution),高速下行分组接入往4G发展的过渡版本,被俗称为3.9G。 长期演进技术是应用于手机及数据卡终端的高速无线通讯标准,该标准基于旧有的GSM/EDGE和UMTS/HSPA网络技术,并使用调制技术提升网络容量及速度。该标准由3GPP(第三代合作伙伴计划)于2008年第四季度于Release 8版本中首次提出,并在Release 9版本中进行少许改良。

虽然长期演进技术被电讯公司夸大宣传为“4G LTE”,实际上它不是真正的4G,因为它没有符合国际电信联盟无线电通信部门要求的4G标准(也就是国际行动电信升级版);长期演进技术升级版才符合国际电信联盟无线电通信部门要求的4G标准。
