• IMT- 2000 is 3G
• 3G is a term coined by the global cellular community to indicate the next generation of mobile service capabilities, e. g., higher capacity and enhanced network functionalities, which allow advanced services and applications, including multimedia.
• IMT- 2000 (International Mobile Telecommunications-2000) is the ITU globally coordinated definition of 3G covering key issues such as frequency spectrum use and technical standards.
• Multiple radio technology options have been included in the IMT-2000 standard to allow seamless service evolution from the various 2G mobile standards that are extensively deployed around the world.

What is CDMA?
• Code Division Multiple Access (CDMA) is a digital wireless technology that was pioneered and commercially developed by QUALCOMM.
• CDMA works by converting speech into digital information, which is then transmitted as a radio signal over a wireless network.
• Using a unique code to distinguish each different call, CDMA enables many more people to share the airwaves at the same time - without static, cross-talk or interference.
