Background

Compared to 1xRTT (CDMA2000 1x) networks currently being used by operators, or the GPRS and EDGE networks employed by their GSM competitors, 1xEV-DO is significantly faster, providing access terminals (mobile devices) with air interface speeds of up to 2.4576 Mb/s with Rev. 0 and up to 3.1 Mb/s with Rev. A. Only terminals with 1xEV-DO chipsets can take advantage of the higher speeds. HSDPA is a competing technology for UMTS (W-CDMA) networks standardized in 3GPP. CDMA2000 is a 3G mobile telecommunications standard, one of the approved radio interfaces for the ITUs IMT-2000 standard, and a successor to 2G CDMA (IS-95, branded cdmaOne). ...

The family of standards 1xEV-DO is a part of, CDMA2000, was originally called cdma2000; the title of the 1xEV-DO standard, denoted as IS-856, is "cdma2000 High Rate Packet Data Air Interface Specification." The latest version of the 1xEV-DO standard can be found in C.S0024-A v2.0. The initial design of 1xEV-DO was developed by Qualcomm in 1999 to meet IMT-2000 requirements for a greater than 2 Mbit/s downlink for stationary communications. Initially, the standard was called HDR (High Data Rate), and was renamed to 1xEV-DO after it was ratified by the ITU. The name stood for "1x Evolution - Data Only", referring to its being a direct evolution of the 1x air interface standard, with its channels carrying only data traffic. Later, due to the possible negative connotations of the word "only" in marketing, the "DO" part of the standard's name was changed to stand for "Data-Optimized". So 1xEV-DO now stands for "1x Evolution - Data-Optimized", providing a more marketing-friendly emphasis that the technology was optimized for data transfers. CDMA2000 is a family of 3G mobile telecommunications standards that use CDMA, a multiple access scheme for digital radio, to send voice, data, and signaling data (such as a dialed telephone number) between mobile telephones and cell sites. ... 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) is an international organization established to standardize and regulate international radio and telecommunications. ... CDMA2000 is a family of 3G mobile telecommunications standards that use CDMA, a multiple access scheme for digital radio, to send voice, data, and signaling data (such as a dialed telephone number) between mobile telephones and cell sites. ...

When deployed with a voice network, 1xEV-DO requires a separate radio channel of 1.25 MHz. The successor to the first revision of the standard, 1xEV-DO Rev. 0, is called 1xEV-DO Rev. A, and is currently deployed in Japan and Korea. Rev. A will be deployed in the United States by Sprint and Verizon Wireless in 2006. 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 downlink (forward link) data rate from 2.4576 Mb/s in Rev. 0 to 3.1 Mb/s, Rev. A has a 12-times improvement in the maximum uplink (reverse link) data rate, from .15 Mb/s to 1.8 Mb/s. EV-DO Rev. A supports low latency services including VoIP and Video Telephony on the same carrier with traditional Internet packet data services.

Potential Competing Standards

Motorola proposed a new system called 1Xtreme as an evolution of CDMA2000 1x, but it was rejected by 3GPP2 standardization body. Later, a competing standard called 1xEV-DV (which was developed by Qualcomm, Lucent, Nokia, Motorola, etc. in 3GPP2) was proposed as an alternate evolution of CDMA. 1xEV-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. (1xEV-DO requires an overlay network when deployed in mixed mode.) CDMA2000 is a 3G mobile telecommunications standard, one of the approved radio interfaces for the ITUs IMT-2000 standard, and a successor to 2G CDMA (IS-95, branded cdmaOne). ...

It should be noted that 1xEV-DO is technically superior to 1xEV-DV because it did not have to be backward compatible, and thus was free to explore, for example, different pilot structures, reverse link silence periods, improved control channels, etc. In addition, since 1xEV-DO uses an IP network and does not require a SS7 network and complex network switches such as an MSC (mobile switching center), the network cost is less than that of 1xEV-DV. Another factor that affected operators' decision to use 1xEV-DO was equipment was not available for 1xEV-DV in time to meet market demands whereas the 1xEV-DO equipment and mobile ASICs were available and tested by the time the 1xEV-DV standard was completed. As a result, the 1xEV-DV standard was less attractive to operators, and has not been implemented. In fact, with the announcement by Verizon Wireless and later Sprint in 2004 of plans for deployment of 1xEV-DO, and similar announcements by smaller operators in 2005, Qualcomm in March 2005 suspended development of 1xEV-DV chipsets, and focused its efforts toward improving the 1xEV-DO product line. Verizon Wireless, headquartered in Bedminster, New Jersey, owns and operates the second-largest wireless telecommunications network in the United States. ... Sprint refers to: a race or a part of a race, cf. ...
