3G cellular standards are developed by the by the
Third-Generation Partnership Project (3GPP), a joint venture of several
standard organizations such as the European Telecommunications Standards
Institute (ETSI), ANSI, and the Alliance for Telecommunications Industry
Solutions (ATIS) Committee T1. The 3GPP is based on the ITU’s International
Mobile Telecommunications 2000 (IMT-2000) initiative. The characteristics of a
3G wireless standard, motivated by mobility and use of Internet are: (i)
support all mobile applications, (ii) support both packet-switched (PS) and
circuit-switched (CS) data transmission, and (iii) offer high data rates up to
2 Mbps. The most important IMT-2000 proposals are the UMTS and CDMA-2000
(discussed in next two sections). These standards cover both the air interface
and the core network solution. The main effort of 3GPP is to facilitate
convergence of 3G networks, providing seamless global roaming between the
different modes of CDMA 3G.
