Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.
UMTS, short for Universal Mobile Telecommunications System, is a 3G networking standard used throughout much of the world as an upgrade to existing GSM mobile networks. UMTS makes use of WCDMA, a technology that shares much with CDMA networks used throughout the world, though it is not compatible with them. Base level UMTS networks are generally capable of downlink speeds as fast as 384kbps. Newer HSDPA variants are capable of rates as high as 3.6Mbps or more. Originally used only on the 2100MHz frequency band in Europe, UMTS is now supported on the 850MHz and 1900MHz bands in North America.
