CDMA Development Group

CDMA Development Group (CDG)

The CDMA Development Group (CDG), founded in December 1993, is an international consortium of companies who have joined together to lead the adoption and evolution of 3G CDMA wireless systems around the world. The CDG is comprised of CDMA service providers and manufacturers, application developers and content providers. By working together, the members help to ensure interoperability among systems, while expediting the availability of 3G CDMA technology to consumers. More information about the CDG can be found at http://www.cdg.org

Mission
To lead the rapid evolution and deployment of 3G CDMA-based systems, based on open standards and encompassing all core architectures, to meet the needs of markets around the world.

The CDG and its members work together to:
• Accelerate the definition of requirements for new CDMA features, services and applications
• Promote industry and public awareness of CDMA capabilities and developments through marketing and public relations activities
• Foster collaboration and the development of consensus among carriers on critical issues to provide direction and leadership for the industry
• Define the evolution path for current and next-generation CDMA systems
• Establish strategic relationships with government ministries, regulatory bodies, and worldwide standards and industry organizations to promote cooperation and consensus on issues facing the CDMA community
• Serve as the worldwide resource for CDMA-related information
• Minimize the time-to-market of new CDMA-based products and services
• Enable global compatibility and interoperability among CDMA systems worldwide
• Create global economies of scale to make CDMA the preferred choice of operators and end users

About CDMA
CDMA is a "spread spectrum" technology, allowing many users to occupy the same time and frequency allocations in a given band/space. As its name implies, CDMA (Code Division Multiple Access) assigns unique codes to each communication to differentiate it from others in the same spectrum. In a world of finite spectrum resources, CDMA enables many more people to share the airwaves at the same time than do alternative technologies.

The CDMA air interface is used in both 2G and 3G networks. 2G CDMA standards are branded cdmaOne and include IS-95A and IS-95B. CDMA is the foundation for 3G services: the two dominant IMT-2000 standards, CDMA2000 and W-CDMA (UMTS), are based on CDMA.

cdmaOne: The Family of IS-95 CDMA Technologies

cdmaOne describes a complete wireless system based on the TIA/EIA IS-95 CDMA standard, including IS-95A and IS-95B revisions. It represents the end-to-end wireless system and all the necessary specifications that govern its operation. cdmaOne provides a family of related services including cellular, Personal Communications Service (PCS) and fixed wireless (wireless local loop).

CDMA2000: Leading the 3G revolution

CDMA2000 represents a family of ITU-approved, IMT-2000 (3G) standards and includes CDMA2000 1X and CDMA2000 1xEV-DO technologies. They deliver increased network capacity to meet growing demand for wireless services and high-speed data services. CDMA2000 1X was the world's first 3G technology commercially deployed (October 2000).
