Single Carrier (1X) EVolution – Data Only. A high-speed standard for cellular 

 data communications.

Supports Internet connections with data rates up to 3.1 Mbps (downlink from the 
network) and 1.8 Mbps (uplink to the network). Average data rates are roughly: for 
Rev. A: 600 1300 kbps (downlink from the network) and 300 400 kbps (uplink to 
the network); for Rev. 0: 400 700 kbps (downlink from the network) and 40 80 
kbps (uplink to the network). Actual speed depends on the network conditions.

Code Division Multiple Access.
A wideband spread spectrum technique used in digital cellular, personal 
communications services, and other wireless networks. Wide channels (1.25 
MHz) are obtained through spread spectrum transmissions, thus allowing many 
active users to share the same channel. Each user is assigned a unique digital 
code, which differentiates the individual conversations on the same channel.
