![]() GSM later saw the GPRS and EDGE enhancements that introduced packet-switching into GSM networks. UMTS was the 3G migration path for the well-known second-generation GSM networks (Global System for Mobile Communications). CDMA2000, on the other hand, was developed as part of another project, 3GPP2. UMTS is a 3G standard specified by 3GPP (Third Generation Partnership Project), Release 1999. UMTS and CDMA2000 were the leading technologies of the 3G era. UMTS employs WCDMA and uses circuit and packet switching to deliver voice calls, text messages and mobile data with peak speeds of up to 2 Mbps. UMTS (Universal Mobile Telecommunication System) is a third-generation (3G) mobile communications technology that allows 2G GSM networks to migrate to 3G. If you have ever used a 3G USB dongle as an internet source for your laptop, you may already have benefited from UMTS. With 3G, video streaming on a mobile phone became a reality, which played an instrumental role in shaping the mobile broadband market as we know it today. Before 3G, the perception of mobile phones was primarily voice, text and a limited amount of web browsing. While many of us mostly think about 4G and 5G as the key mobile technologies in recent times, the third-generation (3G) cellular technologies arguably were game-changers in the mobile telecom industry. What is 3G UMTS (Universal Mobile Telecommunication System)? UMTS employs Wideband CDMA (WCDMA) for its radio interface to enable peak download data rates of up to 2 Mbps and average download speeds of around 384 kbps. UMTS (Universal Mobile Telecommunication System) is a third-generation cellular technology that allows 2G GSM networks to migrate to 3G. UMTS is the 3G migration path used by the most widely deployed second-generation (2G) technology, GSM. The third generation of mobile networks, also referred to as 3G, is primarily enabled by two cellular technologies: UMTS (Universal Mobile Telecommunication System) and CDMA2000 (Code Division Multiple Access Year 2000).
