LTE（长期演进）是依靠基于3GPP GSM发展道路的演进，并超越了3G HSDPA/HSUPA，其旨在以低于3G的每数据位成本提供更高的数据速度。其目标是当在20MHz频谱分配中运行，并且在下行链路中上升到可实现最高类别UE 的300Mbps峰值速率时，使数据速率在下行链路上超过100MMbps，在上行链路上超过50Mbps。

LTE技术还将确保速度高达120km/h时的高性能以及在速度高达350km/h时的蜂窝网络中实现移动性支持。除更高的数据速率外，另一个目标是实现广域范围覆盖。对于5km信元至30km信元以及最长100km信元，必须实现相应的吞吐量、效率及移动性目标。此外，通过在具有较小IP 分包的无载情况下使数据平面延迟小于5ms，这一目标还将实现更短的延迟。

About LTE technology
LTE (Long Term Evolution) lies on the 3GPP GSM evolutionary path beyond 3G HSDPA/HSUPA and is designed to provide increased data speeds at a lower cost per
data bit compared to 3G. It targets data rates in excess of 100Mbps over the downlink and 50Mbps over the uplink when operating in the 20MHz spectrum allocation, climbing to peak rates of 300Mbps in the downlink for the highest category UEs.

LTE technology will also ensure high performance for speeds up to 120km/h and mobility support across the cellular network for speeds up to 350km/h. As well as higher data rates, wide-area coverage is also being targeted. The throughput, efficiency and mobility targets must be met for 5km cells through to 30km cells and up to 100km cells. Reduced latency is also being addressed with a target for data-plane latency less than 5ms in unloaded conditions with small IP packets.
