Global standardization of IMT-2000

As we usher in the new millennium, the International Mobile Telecommuncations-2000 (IMT-2000) standards are near completion. The much-anticipated standardization of the third generation (3G) wireless systems has been the focus of wireless standards organizations around the world for the last several years. Wireless standards activities have been underway in the ITU-R, ITU-T, TIA, Tl, ARIB, TTC, TTA, ETSI, and CWTS to define the air interfaces, core networks, interfaces and services. Much of this activity has transferred to the Partnership Projects, i.e. 3GPP and 3GPP2, although the regional standards development organizations (SDOs) are still ultimately responsible for the standardization of the detailed specifications for IMT-2000. These standards organizations and regional relationships are shown.
