Evolution Data Only,Evolution Data Optimized, often abbreviated as EVDO, EV-DO, EvDO, 1xEV-DO or 1xEvDO is a wireless radio broadband data protocol being adopted by many CDMA mobile phone providers in Japan, Korea, Israel, the United States and Canada, as part of the CDMA2000 standard. In comparison to the 1xRTT networks being used by these carriers currently or the GPRS and EDGE networks being employed by their GSM competitors, EV-DO is significantly faster, allowing clients download speeds of up to 2.4 mbit/s. Only phones that are enabled for EVDO can take advantage of the higher speeds. With the high speeds projected for this network, this protocol could enable the ideal 3G spec envisioned by FCC regulations, allowing high speed video transmission.

EV-DO is the first stage of the CDMA2000 standard. The next stage will be EV-DV or Evolution Data & Voice. Also EVDO Rev A is under development and will be deployed 2006.

EV-DO networks

The following U.S. companies have EV-DO networks in production:

Bell Mobility is currently constructing an EV-DO network in Canada, with trials underway in the Greater Toronto Area. Full rollout is expected in 2005.

Pelephone 80% of populated area in Israel. Full rollout is expected in 2005.

EV-DO phones

Some phones that are EV-DO enabled are:
