For information on CDMA2000 technologies click here 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:
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. |
