COSTA MESA, Calif. — The CDMA Development Group (CDG) (http://www.cdg.org) announced today that the number of CDMA2000(r) operators reached 143 at the end of the last year, and the technology is now deployed in 67 countries across 6 continents. Furthermore, the number of 1xEV-DO networks nearly doubled from 16 to 29 in 2005, highlighting the industry’s rapid transition to advanced broadband wireless services. CDMA2000 momentum will continue in 2006, with 30 new operators scheduled to deploy commercial networks (compared to 20 last year) and 21 additional trials underway. The number of 1xEV-DO networks will reach 70 in the coming months, and 1xEV-DO Rev A will enter the commercial phase.
“CDMA2000 is rapidly expanding across all markets, demonstrating that 3G is the technology of choice for developed and developing countries,'’ said Perry LaForge, executive director of the CDG. “CDMA2000 is the most widely deployed 3G technology today, already serving 10% of the total wireless users worldwide, and is at least two years ahead in the evolution to broadband and next generation all-IP services.'’

 

 

Designed to support in-band migration as well as new frequencies allocated to IMT-2000, CDMA2000 has been deployed by cdmaOne(tm), TDMA, analog and Greenfield operators across a broad range of frequencies including the 450, 800, 1700, 1900 and 2100 MHz bands in Africa, Asia, North and Latin America, and Europe. First introduced by operators in the advanced wireless markets of Asia and North America, CDMA2000 has quickly spread to developing regions; today, Latin America, South East and Central Asia and Africa are the fastest growing markets for CDMA2000, accounting for more than 50% of all networks deployed.
Asia is still the largest market for CDMA2000 with 36 operators in 19 countries, including China, India, Japan, Korea, Taiwan and Indonesia. Asian CDMA2000 operators are leaders in commercializing advanced wireless technologies; Korea was first to introduce 1xEV-DO broadband services, and now seven operators in the region have launched it and 11 more are in deployment.
Most cdmaOne carriers and a number of TDMA operators in North America have migrated to CDMA2000. There are 26 operators offering CDMA2000 1X services and seven have deployed 1xEV-DO, including Verizon Wireless, Sprint Nextel, and Alltel. One more 1X and 3 1xEV-DO networks are scheduled to be commercial in 2006.

Introduction to CDMA technology

Filed under: CDMA Technology — info @ 9:30 am

CDMA is one if the majoe global wireless mobile technology standards. Other standards being GSM and TDMA Code division multiple access (CDMA) is a form of multiplexing (not a modulation scheme) and a method of multiple access that does not divide up the channel by time (as in TDMA), or frequency (as in FDMA), but instead encodes data with a certain code associated with a channel and uses the constructive interference properties of the signal medium to perform the multiplexing. CDMA also refers to digital cellular telephony systems that make use of this multiple access scheme, such as those pioneered by Qualcomm, or W-CDMA. CDMA is primarily a North American technology developed by Department of defence first and perfected by Qualcomm. GSM is primarily European technology
