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.
