CDMA technology enables the U.S. Federal Government to quickly add new services while keeping operating costs in check. Evolution-Data Optimized (EVDO) Rev. A represents the evolution of CDMA2000 technology, bringing increases in efficiency, data speeds and capacity to existing CDMA2000 1X and 1xEVDO networks.
CDMA2000 1xEVDO enables the U.S. Federal Government to provide agencies with continuous, anytime, anywhere access to mission-critical, broadband data applications—with performance, coverage and reliability.
CDMA2000 1xEVDO is the data evolution beyond CDMA2000 1X (voice and basic packet data), optimized to support data for high-bandwidth applications. It offers a real-world peak data rate of 3.1 Mbps on the forward link – equivalent to DSL – and peak data rate of 1.8 Mbps on the reverse link. Current software upgrades are being deployed that drive these rates even higher, tripling them: the current forward link speeds up to 9.3 Mbps and up to 5.4 Mbps on the reverse. Add a new hardware component, and the forward link can achieve speeds of 14.7 Mbps, while the reverse link remains at 5.4; its capacity is improved by 50 percent.
On the horizon are further improvements to both the voice and data capabilities of CDMA2000. CDMA2000 1XAdvanced has the potential of tripling the voice capacity of a 1X carrier while providing the same network coverage, or increasing the coverage by 70 percent with the same voice capacity.
U.S. Federal Government customers can maximize the value of their networks, offering an ever increasing range of features and capabilities, and be confident that at the point 4G makes sense for them, their networks will easily integrate these new services alongside their existing 3G assets.
