LTE（LongTermEvolution，长期演进)是由3GPP（The3rdGenerationPartnershipProject，第三代合作伙伴计划）组织制定的UMTS（UniversalMobileTelecommunicationsSystem，通用移动通信系统）技术标准的长期演进，于2004年12月在3GPP多伦多会议上正式立项并启动。LTE系统引入了OFDM（OrthogonalFrequencyDivisionMultiplexing，正交频分复用）和MIMO（Multi-Input&Multi-Output，多输入多输出）等关键技术，显著增加了频谱效率和数据传输速率（20M带宽2X2MIMO在64QAM情况下，理论下行最大传输速率为201Mbps，除去信令开销后大概为150Mbps，但根据实际组网以及终端能力限制，一般认为下行峰值速率为100Mbps，上行为50Mbps），并支持多种带宽分配：1.4MHz，3MHz，5MHz，10MHz，15MHz和20MHz等，且支持全球主流2G/3G频段和一些新增频段，因而频谱分配更加灵活，系统容量和覆盖也显著提升。[1]
