Wireless Operators Announce Agreement on Globally Harmonized Third- Generation (G3G) Code Division Multiple Access Standard.

TORONTO, June 8 /CNW-PRN/ - A historic harmonization agreement has been reached by major wireless operators and equipment suppliers around the world on a standard for a new generation of wireless systems.

The agreement on a harmonized 3G CDMA standard is a significant step forward in global industry co-operation. If the harmonization agreement is adopted by the appropriate standards bodies, consumers will enjoy a host of benefits, including seamless global roaming, lower-cost handsets and airtime, and a proliferation of new communications services, including high-speed data applications carried at peak rates of upto 2 Mbps.

The agreement, forged by members of the Operators Harmonization Group, chaired by Madame Li Mofang of China Telecom, during a recent meeting in Toronto, focused on a harmonized global Code Division Multiple Access (CDMA) family of 3G standards, and offers operators a clear transition path from today's 2nd generation mobile systems to this new technology.

The meetings were attended by more than 30 of the world's largest wireless operators and more than a dozen wireless equipment manufacturers, representing all of the world's major wireless standards. The Toronto meeting was the last in a series of meetings scheduled to discuss the final technical parameters of a globally harmonized G3G CDMA standard.

The Toronto agreement represents a win for the entire industry and for consumers. This collaboration brings the world a step closer to the high-bandwidth, consumer-friendly wireless networks of the future.

Members of the OHG have compiled a Technical Framework Document that will be submitted to the various world standards organizations. The document will serve as a blueprint of agreed-upon technical issues for regional standards bodies to consider and implement as they establish a final G3G CDMA standard. This process will be initiated when the agreement is formally presented at a meeting of the world standardization body of the United Nations known as the International Telecommunications Union (ITU) being held in Beijing today. The companies that support this submission to the ITU will undertake the steps necessary to facilitate its progress through all the relevant industry organizations and have established a transition team for this purpose.

The agreement effectively addresses the needs of both the W-CDMA and cdma2000 communities to form specifications for a Direct-Sequence CDMA mode, a Multi-Carrier CDMA mode and a Time Division Duplex CDMA mode within the harmonized G3G CDMA standard.

The foundation of a technical harmonization agreement for each mode was developed after thorough technical discussions concerning the similarities and benefits of various CDMA approaches. It was evident as a result of this discussion that all proposals had very similar fundamental building blocks required for CDMA systems. This common understanding of the similarities of the ITU 3G proposals was a key enabler to reaching agreement between operators and manufacturers alike. Without attempting to repeat the details of the technical discussion here, a simple description of the technical harmonization agreement follows.

The Direct Sequence mode will utilize a chip rate of 3.84 Mcps and will support asynchronous and synchronous operation incorporating the concepts of all the 3G Direct Sequence proposals to the ITU. The Multi-Carrier mode will utilize a chip rate of 3.6864 Mcps and will support synchronous operation to ensure it can overlay existing cdmaOne networks. The Time Division Duplex mode will have a chip rate of 3.84 Mcps and will draw from the various 3G ITU Time Division Duplex proposals. These harmonized parameters will permit the development of inexpensive, multimode handsets and infrastructure. In addition, the agreement also provides for efficient and effective support of all three CDMA modes on both ANSI-41 and GSM-MAP networks.

The focus of the OHG activities have centered on CDMA systems, however, IS 136 TDMA operators also participated in this harmonization activity. Members of the OHG believe that the ITU 3G standards should also encompass a TDMA based 3G standard that draws on the TDMA based 3G proposals that have been submitted to the ITU.

The harmonization agreement for the 3G CDMA modes supports previous standards efforts of the ITU-R TG 8/1 committee as well as the guidelines established by the TransAtlantic Business Dialogue.

The document entitled ``Harmonized Global 3G (G3G) Technical Framework for ITU IMT-2000 CDMA Proposal'' is currently supported by the following companies, although it is expected that other companies will also support this framework in the future:
