Motorola_CDMA 2000 EV-DO Revision B EXECUTIVE SUMMARY CDMA2000 is a 3G technology consisting of voice and data traffic. Voice traffic is often referred to as CDMA 2000 1X and data as CDMA EV-DO. The CDMA 2000 delivers the highest voice efficiency in the wireless industry, and EV-DO is clearly the market leader for high speed wireless mobile broadband. EV-DO provides service provider’s with an efficient and orderly network evolution (upgrades consisting primarily of software and channel cards). The migration through EV-DO Revisions 0, A, B, and C provides the service provider with a cost effective means to upgrade the network capability. Multi-carrier EV-DO Revision B (EV-DOrB) delivers the means to compete aggressively with other services in the rapidly expanding market for wireless mobile broadband. Multi-carrier EV-DO Revision B advances the industry by delivering higher data rates. Consumers will appreciate the enhanced user experience made possible by the higher data rates of EV-DO Revision B (EV-DOrB). In its fullest manifestation, EV-DOrB improves both forward and reverse link air interface capability by several means, including, but not limited to: • Higher data rates with aggregating multiple carriers to deliver traffic faster • Dynamic load balancing to increase overall throughput • Increased performance with a flexible frequency reuse approach • Support for existing EV-DO subscriber devices EV-DOrB can be implemented with a software upgrade when multiple EV-DOrA carriers are deployed. A service provider can then grow into the higher performance of EV-DOrB as the market gains momentum. Multi-carrier EV-DOrB can be implemented with two or three carriers, leveraging the scalability of the technology. [ Last edited by ccjjhh on 2009-3-25 at 08:36 ] |
