This is the Data only or Data Optimised evolution for CDMA2000. As the name implies this standard is optimised for data only and can offer data rates up to 2.45 Mbps under Release 0 of the standard or 3.1 Mbps under Release A. It uses separate channels from the existing 1X standard, and if voice traffic is to be handled an “Access Terminal” capable of using 1X must be used and this is carried on a different channel to the data. The EV-DO standard is defined under IS-856.
Phase 1 evolution of CDMA2000 1xRTT where the 1.25 MHz carrier supports data only. It increases the crucial forward data rate to 2.4 Mbps. Also called IS-856.
An evolution of CDMA2000, this "data-optimized" version is also an approved 3G standard. 1xEV-DO provides peak data rates of up 2.4 Mbps in a standard 1.25 MHz CDMA channel for fixed, portable and mobile applications.
(Evolution Data-Only). CDMA2000 1XEV represents the second step in the evolution of CDMA2000. Commercially launched in 2001, offers data speeds of up to 2.4 Mbps on a separate 1.25 MHz carrier.
a.k.a. EV-DO, DO CDMA2000 1X Evolution - Data Optimized. Third-generation wireless technology that offers broadband data speeds to support applications such as VPN access, video downloads and large file transfers. CDMA2000 1xEV-DO is a direct evolution of CDMA2000 1X. See Also: IMT2000, CDMA2000
A 3G wireless communications standard further evolved from CDMA2000 technology. It is a standard optimized for data transmission providing a peak data rate of 2.4 Mbps with a typical user experience of 300 - 800 kbps. 1xEV-DV is optimized for both data and voice transmissions.
The next evolution of CDMA2000 1X, referred to as 1xEV-DO, which provides “always on†data packet connections. CDMA2000® 1xEV-DO is "data optimized," providing peak data rates of up to 2.4 Mbps in a standard 1.25 MHz channel used exclusively for data. CDMA2000 1xEV-DO provides average throughput speeds of over 700 Kbps – comparable to wireline DSL services – and fast enough to support applications such as streaming video and large file downloads.
CDMA2000 1xEV-DO Rev 0 (1xEvolution Data Optimized) is a third-generation (3G) broadband wireless packet data technology optimized for high-speed mobile data applications. Standardized by the TIA as TIA/EIA/IS-856 “CDMA2000 High Rate Packet Data Air Interface Specification”, EV-DO Rev 0 technology is being used by service providers around the world to deploy broadband wireless data networks or to add or increase the data capacity of their existing CDMA IS-95 or 1xRTT networks.
