GPRS (General Packet Radio Service) and EDGE (Enhanced Data Rates for GSM Evolution) provide data capabilities in widely deployed 2G networks reaching peak and average data rates of 384kpbs and 200kbps, respectively. Within 3GPP Release 7, further improvements to GPRS/EDGE have been specified in the context of EDGE evolution. This application note introduces key features of EDGE evolution and outlines the changes to the radio interface.
