What is 1xEV-DO (1× Evolution Data Only Air Interface)?

It is an evolution of the CDMA 2000 standard. Evolution of data only technology uses advanced multiplexing techniques like CDMA (Code division multiple access ) and TDM (Time division multiplexing ) to maximize the data rates. The EV-DO channel has a bandwidth of 1.25 MHz. This feature of CDMA 2000 networks provides access to mobile devices with forward link with a speed of 2.4 mbps .
