Evolution History of EV-DOEV-DO Rev.0 is designed as a “Wide-Area Mobile Wireless Ethernet”
Optimized support for downlink intensive (asymmetric), delay-tolerant applications such as Web browsing, File Transfer, WAP, IM etc. But can not support such applications with delay-sensitive applications with symmetric data rates as VoIP, Video Telephony etc.
1xEV-DO Revision A Further improves spectral efficiency and peak rate of forward/reverse link. On the other hand, lots of mechanisms are designed to strengthen support for real-time service by the system. By introducing more refined rate grade division, more efficient resource allocation algorithm, shorter end-to-end delay and QoS differentiation of multiple flows, 1xEV-DO RevA can effectively support QoS requirements of various applications.
Some upper-layer features of 1xEV-DO Rev A can run on the DO Rev. 0 hardware, such as BCMCS and QoS differentiation, and they form enhanced DO.

EV-DO: Unceasingly-Evolving IP WANThe EV-DO evolves forward in three directions, that is, better spectralefficiency (bits/Hz), stronger service feature (Low latency service, Multicast), and higher peak rate.
The DO evolves from Rev.0 to Rev.A and from Rev.A to Rev.B in a smooth manner. The new standard is compatible with the former standard. All system bands take 1.25 MHz as the basic unit, facilitating the smooth transition of operators.
Designed for wider frequency blocks (up to 20MHz) with higher peak rates and higher spectral efficiency
Highly optimized QoS for VoIP and other low delay apps, designed for more symmetric IP traffic.
Designed for asymmetric IP traffic and Best Effort applications, such as FTP, Web browsing.

18
Benefits: TrFO
TrFO (Transcoder Free Operation) is a mechanism for configuring a call so that no transcoders are needed in the network.
TrFO achieves bandwidth efficiencies in the bearer stream and reduces round trip delays introduced by unnecessary transcoding.
Also, TrFO may increase voice quality.
19
Benefits: RTO
RTO (Remote Transcoder Operation) is a mechanism for configuring a call so that only one transcoder resource is needed in the network.
RTO is just a special case of TrFO.

12Kbps
21
Benefits (2): Bandwidth Efficiency, IP Backhaul Dynamics
TDM switch or softswitch using TDM interfaces adopts a 64Kbps circuit for each voice call.
For All-IP, we can use EVRC for voice, the rate of EVRC is only 8Kbps. EVRC is a multi-rate voice codec that supports variable rate transmission of speech based on voice activity.
The highest rate of EVRC is called Full Rate. The vocoder also produces signals at Half Rate signal and an Eighth Rate signal depending on speech characteristics.
Multiple frames can be carried by one IP packet, so the overhead will be shared by multiple frames, further improve the bandwidth efficiency.

Benefits Summary ofCDMA2000 All-IP Network
Benefits of All-IPIP transport between NEs:
Flexible network deployment, and flexible transmission selection; Flat networking using IP routers and no need to deploy Tandem MGW in IP network. Cost savings for transmission bandwidth between MGW and BSC, (Save up to 80.5% bandwidth compared with TDM)Cost savings for transmission bandwidth between MGW and MGW for local and toll call (save up to 85.4% compared with G.711 over IP)Toll call via IP network not TDM network, less cost for toll call means more revenue and competitive edge
TrFO/RTOCost savings for vocoders (up to 30%-40% or even more)Improved voice quality (less round trip delay, higher MOS)
Smooth migration to All-IP network and IMS, no need to consider hardware replacement in the futureBCMCS support (multi-cast and broadcast is a unique feature of IP network)
