IMT-2000

In all, these technologies fall under the ITUs generic name of IMT-2000 (International Mobile Telecommunications 2000). But when the ITU tried to unify and standardise 3G technologies, no consensus was reached. There were thus five terrestrial standards developed as part of the IMT-2000 program. Instead, depending on where in the world 3G will be implemented, the 3G standard will be based on CDMA variants cdma2000 or W-CDMA.
