3G connectivity of mobile telecommunications technology popularly known as 3G is an International Telecommunication Union (ITU) specification that promised an increase in bandwidth of up-to 384kbps.

This  was based on a set of standards used for mobile devices, mobile telecommunications, services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the ITU.

3G made possible; application in wireless access, Internet access, video calls and mobile TV. 3G telecommunication networks support services that provide an information transfer rate of at least 200 kbit/s.

The 3G technology is the result of research and development projects of the ITU which begun in the early 1980s and 1992 after the ITU approved five radio interfaces for IMT-2000 as part of the ITU-R M.1457 for UMTS and CDMA2000. WiMax was added in 2007 based on recommendation.

3G specifications and standards took fifteen years to develop in the IMT-2000. 3G communication spectrum is between 400MHz to 3GHz allocation which was approved by both governments and communication companies. 3G ensured the effective use and implementation of wireless voice telephony, mobile internet access, fixed wireless internet access, video calls and the mobile TV technology 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. Several telecommunications companies market wireless mobile Internet services as 3G, indicating that the advertised service is provided over a 3G wireless network.

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.

However, many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service. 3G releases, often denoted as 3.75G  also provide access of several to  and in laptop computers.

The following standards are typically branded 3G: UMTS  system. First offered in 2001, standardized by and used primarily in Europe, Japan, China (however with a different radio interface) and other regions predominated by system infrastructure.

The cell phones are typically UMTS and GSM hybrids. Several radio interfaces are offered, sharing the same infrastructure.
