WWAN
Wireless Wide Area Network (WWAN). Also called "wireless broadband" or "broadband
wireless," wireless WANs (WWANs) use cellular towers to transmit a wireless signal over a
range of several miles to a mobile USB modem compared to wireless Wi-Fi LANs (WLANs),
which span only a few hundred feet and generally to only stationary USB modems.
Mbps
Megabits per second - rate of data flow
Kbps
Kilobits per second - rate of data flow
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.
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 USB modems around the world. The
increased data rates on Rev. A's physical layer enable richer applications and services. For
