Generations of Mobile Communications Networks:
In the 1980s, first generation (1G) mobile systems arrived in Nordic countries. These First generation systems were characterized by analog wireless communications and limited Support for user mobility.
Digital communications technology was introduced with second generation (2G) mobile systems in the 1990s. Second generation systems benefited from the cellular concept in which scarce radio resources are used simultaneously by several mobile users without interference. Early 2004, first third generation (3G) mobile systems have been deployed in several European countries. With 3G systems, various wireless technologies converge with Internet technologies.
Telecommunications Context: Standardization and Regulation:
In the telecommunications environment, Standard Development Organizations (SDOs) provide the necessary framework for the development of standards. In the early days of mobile communications, various regional SDOs developed specifications for network technologies and services independently. In 1998, such an effort was initiated by several SDOs including ARIB (Japan), ETSI (Europe), TTA (Korea), TTC (Japan), and T1 (USA). The initiative was named the Third Generation Partnership Project (3GPP).
