GSM增强数据率演进（Enhanced Data rates for GSM Evolution，缩写：EDGE），是一种移动电话通信技术，作为一个2G和2.5G（GPRS）的延伸，有时被称为2.75G。这项技术工作在TDMA和GSM网络中。EDGE（通常又称为：EGPRS）是GPRS的扩展，只要MS和BTS设备做一些必要的升级，就可以工作在任何已经部署GPRS的网络上。

Enhanced Data rates for GSM Evolution (EDGE) (also known as Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT-SC), or Enhanced Data rates for Global Evolution) is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM. EDGE is considered a pre-3G radio technology and is part of ITU's 3G definition. EDGE was deployed on GSM networks beginning in 2003 – initially by Cingular (now AT&T) in the United States.
