Universal Mobile Telecommunication System—Long Term Evolution (UMTS-LTE)
14.1 Introduction
In Europe, the main standardization bodies involved in wireless specifications are the ITU (International Telecommunications Union), the ETSI (European Telecommunications Standardization Institute), and the 3GPP/3GPP2 (3rd Generation Partnership Project). The IMT2000 (International Mobile Telecommunications for beyond year 2000) is a set of standards created for mobile communications to meet ITU specifications.
The 3GPP is the GSM (Global System for Mobile communications) evolution standardization group within IMT2000. The 3GPP is a partnership of several partner members that are standardization organisms in different countries: ARIB (Association of Radio Industries and Businesses) from Japan, ATIS (Alliance for Telecommunications Industry Solutions) from North America, CCSA (China Communications Standards Association), ETSI, TTA (Telecommunications Technology Association) from Korea and TTC (Telecommunications Technology Committee) from Japan.
3GPP2 is the standardization group for cdma2000 (code division multiple access 2000) within ITU's IMT2000 project and is a partnership of ARIB/TTC (Japan), CCSA (China), TIA (Telecommunications Industry Association) from North America, and TTA (Korea).
The first generation of wireless technologies was analog, being the main technologies TACS (Total Access Communication System) in Europe and AMPS (Advanced Mobile Phone Service) in the USA. ...
