CDMA2000 offers operators a robust, long-term evolution path that delivers the performance and economics to meet the rapidly evolving needs of the mobile market place over the long-term. The CDMA2000 evolution path is built on the principle of backward and forward compatibility, in-band migration, and support of heterogeneous networks. CDMA2000 offers some of the highest voice capacity and data rates, and lowest latencies among the leading wide area network technologies available today to deliver high-quality voice and broadband multimedia data services. Most of the technology enhancements are enabled through software upgrades. Building on this solid foundation and flexibility, future enhancements will further strengthen the performance and economics of the core technology and support the convergence of fixed, mobile and broadcast networks through the implementation of all-IP end-to-end solutions. CDMA2000 incorporates advancements in antenna technology, interference cancellation, smart network techniques, modulation and multiplexing to increase its performance and value. With 1X Advanced, the voice capacity of CDMA2000 1X will increase by a factor of four, and the data throughputs and capacity of EV-DO will increase by another factor of four with the implementation of EV-DO Rev. B and DO Advanced. 1X Advanced enables operators to offer a lower cost per call, more minutes of use, or the ability to enable unlimited voice services. The technology also enables operators to tradeoff voice capacity for 70% more coverage or increase broadband revenue by freeing up channels that can be used for broadband data services. Besides offering better speeds, DO Advanced enables operators to add broadband network capacity where and when it is needed. The combination of EV-DO Rev. B and DO Advanced will offer better speeds, increased sector capacity, reduced latency and advanced quality of service features. CDMA2000 technologies will continue to interoperate and coexist with wider-bandwidth OFDM-based technologies such as 802.11n for wireless local area network (WLAN) connectivity and LTE.
CDMA2000 will offer global roaming, ubiquitous high-performance mobile broadband and voice services with a defined evolution path, while OFDMA solutions will augment CDMA2000 capacity by leveraging wider-bandwidths and MIMO antennas in densely populated hot-zones where the demand for broadband connectivity is extremely high. CDMA2000 will evolve and remain a key source of revenue in both developed and emerging markets for well into the next decade.
