General Packet Radio Service (GPRS) and Enhanced Data Rates for GSM Evolution (EDGE) 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
