A comprehensive list of mobile telecommunications networks using third-generation Universal Mobile Telecommunications System (UMTS) technology. The list covers networks deployed on different frequencies and bands, and their launch dates and roaming capabilities.
Learn about the radio frequencies used by 3G wireless networks based on the UMTS standard. See the list of UMTS frequency bands, their common names, channel bandwidths, and duplex gaps.
UMTS is a 3G mobile cellular system based on the GSM standard and using wideband code-division multiple access (W-CDMA) radio access technology. It supports voice, text, MMS and data services, and can achieve high data transfer rates up to 42 Mbit/s.
3G is the third generation of wireless mobile telecommunications technology, offering faster data transfer and better voice quality than 2G. It is based on a set of standards used for mobile devices and networks that comply with the IMT-2000 specifications set by the ITU.
Learn about the communication channels used by 3G wireless UMTS networks. The web page lists and describes the physical, transport and logical levels of UMTS channels, with their names, full names, descriptions and UL/DL indicators.
In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM.
UTRAN is the network and equipment that connects mobile handsets to the public telephone network or the Internet. It consists of Node Bs, RNCs, and interfaces such as Iu, Uu, Iub and Iur.
