Third Generation Partnership Project 2 (3GPP2)

A collaboration between groups of telecommunications associations to standardize 3G (third generation) mobile phone system specifications. The specifications are those established by the CDMA2000 family of standards.

3GPP2 is the standard body behind the competing 3G standard CDMA2000 that is the 3G upgrade to networks used mostly in the United States (and to some extent also in Japan, China, Canada, South Korea, and India). 3GPP2 should not be confused with Third Generation Partnership Project (3GPP).
