International Telecommunications Union (ITU) Recognizes CDMA2000 1xEV-DO as an IMT-2000 Standard; CDMA2000 Reaches Another Milestone and Broadens Its Lead.Business Editors/High-Tech Writers COSTA MESA, Calif.--(BUSINESS WIRE)--Aug. 13, 2001 The CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. Development Group (CDG (CDMA Development Group, Costa Mesa, CA, www.cdg.org) A membership organization founded in 1995 that promotes CDMA wireless systems worldwide. It is involved with developing new features and services and promoting standards that provide global compatibility and interoperability. ) (www.cdg.org) reported today that CDMA2000 1xEV-DO (Data Only) has been recognized as a 3G IMT-2000 standard by the International Telecommunications Union See ITU. (body, standard) International Telecommunications Union - (ITU) ITU-T, the telecommunication standardisation sector of ITU, is responsible for making technical recommendations about telephone and data (including fax) communications systems for PTTs and suppliers. (ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. ) at the ITU-R ITU-R ITU Radiocommunication Sector WP8F conference recently held in Stockholm. The standard will be submitted to ITU-R SG-8 for formal approval during the November meeting in Geneva Geneva, canton and city, Switzerland Geneva (jənē`və), Fr. Genève, canton (1990 pop. 373,019), 109 sq mi (282 sq km), SW Switzerland, surrounding the southwest tip of the Lake of Geneva. . CDMA2000 1xEV (for 1X Evolution) is part of the evolution of CDMA2000 1X, a commercially available IMT-2000 standard that offers data speeds up to 307kbps and is being deployed by carriers around the world. CDMA2000 1xEV-DO is optimized to support 2.4Mbps peak rate in a standard 1.25MHz channel for fixed, portable and mobile applications. A number of operators around the world are testing CDMA2000 1xEV-DO, and SK Telecom and KT Freetel in Korea have announced plans to launch it commercially early next year. "We are very pleased with the work the ITU is doing in continuing to evolve the IMT-2000 family of standards," said Perry LaForge, executive director of the CDG. "The CDMA2000 standards allow operators to 'do more with less,' and deploy enhanced capabilities in a very small amount of spectrum. Furthermore, these standards are not limited to cdmaOne(TM) operators, but are available to TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). , analog, GSM and new 3G licensed operators as well." LaForge continued, "It now appears that CDMA2000 is one of the few brightspots in the highly confused 3G marketplace. The cost and time to market advantages of the CDMA2000 standards as a migration path for TDMA, GSM and CDMA operators is well documented in a number of studies (see www.cdg.org). Unlike other migration paths currently under discussion, CDMA2000 is real and its advantages are clear. CDMA2000 1xEV-DO only enhances these advantages by providing extremely high throughput in a small amount of spectrum, providing wireless service providers with a very compelling broadband access solution when compared to wired solutions, such as DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary and cable." The CDMA Development Group is a nonprofit trade association formed to foster the worldwide development, implementation and use of cdmaOne(TM) and CDMA2000. The 110 member companies of the CDG include many of the world's largest wireless operators and equipment manufacturers. The primary activities of the CDG include development of CDMA features and services, public relations, education and seminars, regulatory affairs and international support. Currently, there are more than 500 individuals working within various CDG subcommittees on CDMA-related matters.
