2.3.3.2 Code Division Multiple Access 2000 (CDMA2000)

2.3.3.2 Code Division Multiple Access 2000 (CDMA2000):

 CDMA2000 (with the ITU name IMT-2000 CDMA Multi-Carrier) represents a family of technologies that includes CDMA2000 1X and CDMA2000 1xEV:

• CDMA2000 1X can double the voice capacity of CDMAOne networks and delivers peak packet data speeds of 307 kbps in mobile environments. 

• CDMA2000 1xEV includes:
• CDMA2000 1xEV-DO. CDMA2000 1xEV-DO delivers peak data speeds of 2.4Mbps and supports applications such as MP3 transfers and video conferencing.
• CDMA2000 1xEV-DV. CDMA2000 1xEV-DV provides integrated voice and simultaneous high-speed packet data multimedia services at speeds of up to 3.09 Mbps.

            1xEV-DO and 1xEV-DV are both backward compatible with CDMA2000 1X and CDMAOne. As a more advanced development from the previous CDMAOne system, CDMA2000 supports data communication speeds ranging from 144kbps to 2Mbps, with 144kbps being the maximum possible speed outdoors and 2Mbps being the maximum speed in an indoor environment.

          

  Because CDMA2000 has evolved directly from the previous generation of proven CDMA systems, it provides the fastest, easiest, most cost-effective path to 3G services. While all 3G technologies (CDMA2000, WCDMA and TD-SCDMA) may be viable, CDMA2000 is much further ahead in terms of product development, commercial deployment and market acceptance. The world's first 3G (CDMA2000 1X) commercial system was launched by SK Telecom ( Korea ) in October 2000.

           

 Since then, CDMA2000 1X has been deployed in Asia, North and South America and Europe , and the subscriber base is growing at 700,000 subscribers per day. CDMA2000 1xEV-DO was launched in 2002 by SK Telecom and KT Freetel. The commercial success of CDMA2000 has made the IMT-2000 vision a reality.
