3G Evolution

CDMA2000 has a robust, long-term evolution path that provides operators with significant technology performance, total cost of ownership and time-to-market leadership in the delivery of advanced mobile voice and data services.

  • 1 year lead in the introduction of 3G, with CDMA2000 1X
  • 4 year lead in broadband wireless services, with CDMA2000 1xEV-DO Rel. 0
  • 2-3 year lead in the commercialization of all-IP 3G mobile networks supporting VoIP, multimedia and advanced broadband services, with CDMA2000 1xEV-DO Rev. A
  • 1-2 year lead in delivering next-generation advanced mobile broadband services and the convergence of telecommunications, information technology, consumer electronics, and high-performance multimedia services, with Ultra Mobile Broadband

CDMA2000 ROADMAP


Note: timeline depicts initial commercial availability of each technology. Those introduced beyond 2008 are under standardization and are subject to variability
1
Capacity increase is primarily due to new EVRC-B codec and handset interference cancellation (QLIC)
2
Capacity increase is primarily due to UL and DL interference cancellation and mobile receive diversity
3
Peak rate for 3 EV-DO carriers with software upgrade. Standard supports up to 15 aggregated Rev. A carriers
4
Peak rate for 3 EV-DO carriers with hardware upgrade supporting 64 QAM in the DL. Standard supports up to 15 aggregated Rev. A carriers
5 EV-DO Enhancements include smart network techniques, new device enhancements, 2x2 MIMO support, 64 QAM in the DL and 16 QAM in the UL
6
Operators have the option to only implement software upgrades

Each evolutionary step of CDMA2000 leverages the inherent advantages of CDMA and introduces new technologies and enhancements, including OFDM, OFDMA, MIMO and SDMA, to expand network capacity, increase data rates, reduce latencies, and minimize the cost of delivering services, while preserving previous investments.

Today, CDMA2000 technologies offer the most voice capacity, highest data rates and lowest latencies of any wide area network technology. Building on this solid foundation, future enhancements will further strengthen the performance and economics of the technology and support the convergence of fixed, mobile and broadcast networks through the implementation of All-IP end-to-end solutions.

The underlying principle of the CDMA2000 evolution path is backward and forward compatibility which allows operators to seamlessly and cost-effectively upgrade their existing networks to support enhanced capabilities and advanced services. This backward compatibility is one of the key competitive advantages of the CDMA2000 evolution path and has greatly contributed to its commercial success around the world. Benefits of backward compatibility include:

  • Rapid commercialization and deployment
  • Lower CapEx and OpEx, enabling an improved ROI
  • Investment protection
  • Service transparency for existing and new end-users

Like cdmaOne (IS-95), CDMA2000 standards utilize 2x1.25 MHz radio channels. Future enhancements, including CDMA2000 1xEV-DO Rev. B and Ultra Mobile Broadband (UMB), will enable operators to aggregate up to 15 1.25 MHz channels in 20 MHz of spectrum to deliver higher throughputs and greater network efficiencies.
