This is based on a set of standards used for mobile devices and mobile telecommunications use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the. 3G finds application in wireless voice telephony, access, fixed wireless Internet access, video calls and mobile TV.
3G telecommunication networks support services that provide an information transfer rate of at least 0.2. Later 3G releases, often denoted and, also provide access of several to and in laptop computers. This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies. A new generation of cellular standards has appeared approximately every tenth year since systems were introduced in 1981/1982. Each generation is characterized by new frequency bands, higher data rates and non–backward-compatible transmission technology. The first 3G networks were introduced in 1998 and fourth generation networks in 2008. Contents • • • • • • • • • • • • • • Overview [ ] Several telecommunications companies market wireless mobile Internet services as 3G, indicating that the advertised service is provided over a 3G wireless network.
Inalambrica Con Windows Vista. Services advertised as 3G are required to meet IMT-2000 technical standards, including standards for reliability and speed (data transfer rates). To meet the IMT-2000 standards, a system is required to provide peak data rates of at least 200 kbit/s (about 0.2 Mbit/s). However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service.

Recent 3G releases, often denoted and, also provide mobile broadband access of several to smartphones and mobile modems in laptop computers. The following standards are typically branded 3G: • the (Universal Mobile Telecommunications Service) system, first offered in 2001, standardized by, used primarily in Europe, Japan, China (however with a different radio interface) and other regions predominated by (Global Systems for Mobile) system infrastructure. The cell phones are typically UMTS and GSM hybrids. Several radio interfaces are offered, sharing the same infrastructure: • The original and most widespread radio interface is called (Wideband Code Division Multiple Access). • The radio interface was commercialized in 2009 and is only offered in China. • The latest UMTS release,, can provide peak data rates up to 56 Mbit/s in the downlink in theory (28 Mbit/s in existing services) and 22 Mbit/s in the uplink.
• the system, first offered in 2002, standardized by, used especially in North America and South Korea, sharing infrastructure with the 2G standard. The cell phones are typically CDMA2000 and IS-95 hybrids. The latest release Rev B offers peak rates of 14.7 Mbit/s downstream. The above systems and radio interfaces are based on radio transmission technology. While the standard ('2.9G'), cordless phones and standards formally also fulfill the IMT-2000 requirements and are approved as 3G standards by ITU, these are typically not branded 3G, and are based on completely different technologies.
