1xRTT
Short for single carrier (1x) Radio Transmission Technology. A high speed wireless technology based on the CDMA
platform. 1xRTT has the capability of providing broadband-like speeds of up to 144 Kbps. 1xRTT is also referred to
as CDMA2000.
1xEVDO
Part of a family of CDMA2000 1x digital wireless standards. 1xEVDO is a "3G" standard. EVDO stands for
"EVolution, Data-Optimized." 1xEVDO is based on a technology initially known as "HDR" (High Data Rate) or
"HRPD" (High Rate Packet Data), developed by Qualcomm. The international standard is known as IS-856.
1xEVDO has the capability of providing broadband-like speeds of average speeds of 400-700 kbps.
bps
Bits per second – rate of data flow.
Broadband
High-capacity high-speed, transmission channel with a wider bandwidth than conventional modem lines. Broadband
channels can carry video, voice, and data simultaneously.
Kbps
Kilobits per second – rate of data flow
LAN
Local Area Network. A data network confined to limited area with moderate to high data rates. Does not use
common carrier circuits, although may have gateways or bridges to other public or private networks.
Mbps
Megabits per second
Computing Device
Personal Computing device
PDA
Personal Digital Assistant. A handheld device used for organization, notes, address books, etc.
Rev A
CDMA EV-DO Rev. A is a leading-edge wireless technology with higher data rates and higher system capacity. It is a
fully backward compatible standard and remains interoperable with deployed EV-DO networks and devices around
the world. The increased data rates on Rev. A's physical layer enable richer applications and services.
