1xEV-DO 1x Evolution-Data Only. A 3G Mobile Wireless technology based on CDMA
that offers high-speed, high-capacity wireless Internet connectivity, and is
optimized for packet data services. 1xEV-DO provides a peak data rate of
2.4 Mbps on the forward link within a single 1.25 MHz CDMA carrier.
1xRTT 1x Radio Transmission Technology. A 3G Mobile Wireless technology
based on CDMA that doubles the voice capacity of current CDMA mobile
systems, and adds packet data capability.
3G Third Generation. Generic name for mobile wireless systems used for
offering advanced voice and data services, the first two generations refer to
the existing analog and digital cellular networks respectively. W-CDMA,
1xRTT and 1xEV-DO are the most popular 3G standards.
3GPP A global standards body that is developing 3G standards for the W-CDMA
air interface technology.
3GPP2 A global standards body that is developing 3G standards for the CDMA2000
family of air interface technologies including 1xRTT and 1xEV-DO.
AirVista Airvana’s web-based network management system
Air Interface The Air Interface is the part of a mobile wireless standard that defines the
protocol enabling the subscriber terminal and the radio access network to
interoperate.
ATM A telecommunications method for relaying images, sound and text
simultaneously at very high speeds.
BTS Base Transceiver Station. Radio equipment that cellular operators need to
place at the center of each cell, usually simply called a base station.
BSC Base Station Controller. A wireless network equipment that controls Base
Stations.
carrier An electrical signal that emits at a continuous frequency and carriers data.
Information is encoded onto the carrier by changing the frequency,
amplitude, or phase of the signal (this process is called modulation). The
signal is extracted at the other end through demodulation. Carriers are
modulated and demodulated according to fixed protocols.
CDMA Code Division Multiple Access. A global Mobile Wireless technology based
on a method of sharing frequency among many users by encrypting each
user's signal using a different code.
cell The basic geographical unit of a cellular network, a cell is the area served by
a cell site. Its size varies depending on the terrain, capacity demands, and
strength of the signal from the cell site.
cell site A transmitter/receiver location in a cellular network. The cell site establishes
radio links between the wireless network and the user. The site contains an
antenna tower, transmission radios, and radio controllers.
channel A pair of radio frequencies. One frequency is used for sending and the other
for receiving.
