There have been several revisions of the standard, named alphabetically starting with the first as Rev. A ("revision A") while the first standard is referred to simply as Rev. 0.

[edit] TIA-856 Rev 0

The initial design of EV-DO was developed by Qualcomm in 1999 to meet IMT-2000 requirements for a greater-than-2-Mbit/s downlink for stationary communications, as opposed to mobile communication such as a moving cellular phone. Initially, the standard was called High Data Rate (HDR), but was renamed to 1xEV-DO after it was ratified by the International Telecommunication Union (ITU); it was given the numerical designation TIA-856. Originally, 1xEV-DO stood for "1x Evolution-Data Only", referring to its being a direct evolution of the 1x (1xRTT) air interface standard, with its channels carrying only data traffic. The title of the 1xEV-DO standard document is "cdma2000 High Rate Packet Data Air Interface Specification", as cdma2000 (lowercase) is another name for the 1x standard, numerically designated as TIA-2000. Qualcomm (NASDAQ: QCOM) is a wireless telecommunications research and development company based in San Diego, California. ... IMT-2000 (International Mobile Telecommunications-2000) is the global standard for third generation (3G) wireless communications as defined by the International Telecommunication Union. ... The International Telecommunication Union (ITU; French: Union internationale des télécommunications, Spanish: Unión Internacional de Telecomunicaciones) is an international organization established to standardize and regulate international radio and telecommunications. ... CDMA2000 is a hybrid 2. ...

Later, likely due to the possible negative connotations of the word "only", the "DO" part of the standard's name 1xEV-DO was changed to stand for "Data Optimized". So EV-DO now stands for "Evolution-Data Optimized", the 1x prefix has been dropped by the many major carriers, and is marketed simply as EV-DO.^[1] This provides a more marketing-friendly emphasis that the technology was optimized for data transfers.

[edit] TIA-856 Rev A

Rev. A offers fast packet establishment on both the forward and reverse links along with air interface enhancements that reduce latency and improve data rates. In addition to the increase in the maximum burst downlink rate from 2.45 Mbit/s to 3.1 Mbit/s, Rev. A has a significant improvement in the maximum uplink data rate, from 153 kbit/s to a maximum uplink burst rate of 1.8 Mbit/s. This improvement assumes early acknowledgment of the first subpacket, typical data rates therefore average below 1 Mbit/s.

[edit] TIA-856 Rev B

EV-DO Rev B is a multi-carrier evolution of the Rev A specification. It maintains the capabilities of EVDO Rev A, and provides the following enhancements:

• Higher rates per carrier (up to 4.9 Mbit/s on the downlink per carrier). Typical deployments are expected to include 3 carriers for a peak rate of 14.7 Mbit/s
• Higher rates by bundling multiple channels together enhances user experience and enables new services such as high definition video streaming.
• Uses statistical multiplexing across channels to further reduce latency, enhancing the experience for latency-sensitive services such as gaming, video telephony, remote console sessions and web browsing.
• Increased talk-time and standby time
• Hybrid frequency re-use which reduces the interference from the adjacent sectors and improves the rates that can be offered, especially to users at the edge of the cell.
• Efficient support for services that have asymmetric download and upload requirements (i.e. different data rates required in each direction) such as file transfers, web browsing, and broadband multimedia content delivery.

[edit] Potential competing standards

Motorola proposed a new system called 1Xtreme as an evolution of CDMA2000, but it was rejected by 3GPP2 standardization body. Later, a competing standard called EV-DV developed by Qualcomm, Lucent, Nokia, Motorola, etc. in 3GPP2 was proposed as an alternate evolution of CDMA. EV-DV stands for Evolution-Data and Voice, since the channel structure was backwards compatible with IS-95 and IS-2000 (1xRTT), allowing an in-band network deployment. (EV-DO requires an overlay network when deployed in mixed mode.) Motorola Inc. ... CDMA2000 is a hybrid 2. ... An overlay network is a computer network which is built on top of another network. ...

At the time, there was much debate on the relative merits of DV and DO. Traditional operators with an existing voice network preferred deploying DV, since it does not require an overlay. Other design engineers, and newer operators without a 1x voice network, preferred EV-DO because it did not have to be backward compatible, and so could explore different pilot structures, reverse link silence periods, improved control channels, etc. And the network cost was lower, since EV-DO uses an IP network and does not require a SS7 network and complex network switches such as a mobile switching center (MSC). Also, equipment was not available for EV-DV in time to meet market demands whereas the EV-DO equipment and mobile application-specific integrated circuits (ASIC) were available and tested by the time the EV-DV standard was completed. As a result, the EV-DV standard was less attractive to operators, and has not been implemented. Verizon Wireless, then Sprint Nextel in 2004 and smaller operators in 2005 announced their plans to deploy EV-DO. So in March 2005, Qualcomm suspended development of EV-DV chipsets, and focused on improving the EV-DO product line...
