Single Carrier (1X) EVolution–Data Only
A high-speed standard for cellular packet data communications. It 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 approximately:
•
Rev. A: 600-1300 kbps. (downlink from the network) and 300-400 kbps (uplink
to the network)
•
Rev. 0: 400-700 kbps (downlink from the network) and 40-80 kbps (uplink to
the network)
Actual speed depends on the network conditions. Compare to 1X.
Single Carrier (1X) Radio Transmission Technology
A high-speed standard for cellular packet data communications.
1x supports Internet connections with data rates up to 153
each direction—downlink and uplink). Actual speed depends on the network
conditions. Compare to 1xEV-DO.

3 Generation Partnership Project
3GPP unites 6 telecommunications standard development organizations (ARIB,
ATIS, CCSA, ETSI, TTA, TTC), and provides their members with a stable
environment to produce Reports and Specifications that define 3GPP technologies.
Programming Interface
A protocol intended to be used as an interface by software components to
communicate with each other.
A set of device commands, preceded by "AT" originally developed by Hayes, Inc.
for their devices.
The structure (but not the specific commands, which vary greatly from
manufacturer to manufacturer) is a de facto device industry standard.
CDMA Development Group
A consortium of companies who joined together to lead the adoption and evolution
of CDMA wireless systems around the world.
Also see CDMA.
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.
A IS-95 CDMA standard developed by QUALCOMM Inc.
Also known as TIA-EIA-95.
