What Does Code Division Multiple Access 2000 Mean?

Code Division Multiple Access 2000 (CDMA2000) is a third generation (3G) standard developed by the International Telecommunication Union (ITU). This protocol uses CDMA access to send voice and data and signals between mobile phones and cell sites.


Enhanced services can be provided to CDMA One subscribers through CDMA2000. Data communication speeds ranging from 114 Kbps to 2 Mbps are supported by this standard.

CDMA2000 is also known as IMT-Multi-Carrier or IS-2000.

Techopedia Explains Code Division Multiple Access 2000

The main capacity of CDMA2000 is to deliver a radio interface system that is better than the second generation (2G) systems. In October 2000, SK Telecom (Korea) launched the first commercial system that used this platform (based on the CDMA 2000 1x technology). Since then, several other versions have been developed.

Other technologies include CDMA2000 1xEV-DO (Evolution-Data Optimized) Technologies, which is comprised of several revisions.
