 - EV-DO (1x Evolution-Data Optimized) is a 3G wireless radio broadband data standard that enables faster speeds than are available in existing CDMA networks or other 2G services, such as GPRS or EDGE. EV-DO is pronounced as "E-Vee-Dee-Oh."
EV-DO is the next step in the evolutionary path of CDMA standards, following CDMA2000 and 1xRTTC. EV-DO was developed by Qualcomm in 1999 to meet a
transmission speed target, set by IMT-2000 (International Mobile Telecommunications-2000), of over 2 Mbps for stationary communications. In practice, mobile EV-DO users can expect download speeds of 400-700 Kbps, although speeds over 2 Mbps are possible in areas of high signal strength and low interference. Download speeds are also affected by signal strength.
EV-DO can enable zones of near pervasive computing, in which multiple devices are seamlessly networked with a constant high-speed Internet connection. A user might have constant access to rich media applications and services like IPTV, VoIP and vlogcasting. EV-DO also optimizes VPNs (virtual private networks). Where EV-DO service is not available, EV-DO-enabled handsets or PCI cards automatically switch to 1xRTT or CDMA coverage.
The primary competition for EV-DO in 3G mobile telephony networks in the continental U.S. is HSDPA, which -- unlike EV-DO -- enables simultaneous voice and data transmission.
