1) GSM is the most widely used mobile standard in the world, used by over 2 billion people across 212 countries. It started in the 1980s and provides higher quality digital voice calls at low cost. 2) EDGE is an upgrade to GPRS that allows for higher data transmission rates on existing GSM networks. By using more advanced modulation techniques, EDGE can achieve data rates up to four times faster than GPRS. 3) EDGE provides benefits like minimal network upgrades, global roaming compatibility, and enabling new multimedia services on existing GSM infrastructure at a lower cost than moving directly to 3G.

G US+Canada: EDGE roll-outs on the way E roll-outs on the way and EDGE Market follows global trends. “Ongoing technology standard war”. Also public commitments to EDGE China: Political commitments to every technology. No rush to 3G. No public EDGE commitments yet Europe: WCDMA technology commitment. Strong need for delaying UMTS roll-outs Growing interest towards EDGE, but no public commitments yet. Global EDGE Status
