EV-DO Rev B
CDMA2000 EV-DO is the most widely deployed commercial wireless broadband
technology today with 95 commercial and soon-to-be commercial 1xEV-DO networks
worldwide – in Africa, Asia-Pacific, Europe, North America, Latin America, and the Middle
East – and projected to grow to nearly 350 million users by 20101. This rapid adoption is
attributed to the following.
Leading performance. EV-DO’s performance and feature set continue to maintain a
significant lead over alternative technologies such as UMTS/HSxPA.
Strong support for multimedia content and VoIP. EV-DO Revision A (Rev A) provides
QoS capabilities specifically designed to support bursty, high-rate applications such as
digital video, and delay-sensitive low-rate applications, such as Voice over IP (VoIP).
Efficient use of spectrum. EV-DO provides very efficient spectrum utilization -- delivering
end-user performance superior to that of UMTS/HSxPA using only one quarter the
Clear migration path and backward compatibility. EV-DO continues to evolve on an
aggressive technology schedule with minimal capital investment and full backward
compatibility for multiple generations of handheld mobile devices.
Increased average revenue per users (ARPU). Operators are reporting rapid growth in
ARPU as a result of EV-DO broadband services. KDDI, for example, reported a 14% year-
over-year increase in broadband data ARPU2 in 2006.
EV-DO Revision B (Rev B) is an evolutionary step on the CDMA2000 roadmap, providing
improved support for multimedia content, substantially improved packet data, and VoIP
performance with minimal capital investment (see Figure 1). The standard for Rev B was
published by the Third Generation Partnership Project 2 (3GPP2) and the
Telecommunications Industry Association (TIA) in 2006.
Figure 1 shows alternative, emerging OFDM-based air interface technologies. These
alternatives are primarily designed for wideband 10-20 MHz deployments in new spectrum.
