Third-generation networks deliver faster data speeds over existing 2G networks and also more types of services like broadband access and video telephony. The typical data transfer rates over 3G networks are in the region of 5-10 Megabits per second. Depending on location, 3G networks use either the same spectrum as 2G (in the US) or a different spectrum (in Asia and Europe). 3G-enabled phones are prevalent mostly in Europe and parts of Asia like South Korea and Japan. 3G-derived technologies include HSPA (High Speed Packet Access), WCDMA (Wideband Code Division Multiple Access), and UMTS (Universal Mobile Telecommunication System).
