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 hybrid network configurations.
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.
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, handset interference cancellation (QLIC) and Quasi-Orthogonal Functions (QOF) |
| 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 |
DO Enhancements includes 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 |
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 will incorporate advancements in antenna technology, interference cancellation, modulation and multiplexing to increase its performance and value. It will also interoperate with wider-bandwidth OFDM-based technologies such as WiMAX (802.16d) for backhaul connectivity; DBV-H, MFLO, ISDB-T and T-DMB for high-capacity broadcasting services; 802.11n for wireless local area network (WLAN) connectivity; and LTE and Mobile WiMAX (802.16e) for additional broadband capacity in densely populated hot-zones where the demand for mobile data is extremely high.
