AAA Authentication, Authorization, and Accounting (pronounced "triple a."). A system (or
several systems) that controls what resources users have access to, and keeps
track of the activity of users over the network.
AAS Adaptive Antenna System, also called Advanced Antenna System, is a technology to
enable the network operators to increase the wireless network capacity. In addition,
adaptive antenna systems offer the potential of increased spectrum efficiency,
extended range of coverage and higher rate of frequency reuse. Adaptive antenna
systems consist of multiple antenna elements at the transmitting and/or receiving
side of the communication link, whose signals are processed adaptively in order to
exploit the spatial dimension of the mobile radio channel. Depending on whether the
processing is performed at the transmitter, receiver, or both ends of the
communication link, the adaptive antenna technique is defined as multiple-input
single-output (MISO), single-input multiple-output (SIMO), or multiple-input
multiple-output (MIMO).
ASCII American Standard Code for Information Interchange. A code for representing
English characters as numbers, with each letter assigned a number from 0 to 127.
ASN Access Service Network. An ASN is defined as a complete set of network functions
needed to provide radio access to a WiMAX subscriber. An ASN is comprised of
network elements such as one or more Base Stations (BS) and one or more ASN
gateways (ASN-GW). An ASN may be shared by more than one Connectivity
Service Network (CSN).
ASN-GW Access Service Network Gateway. The ASN-GW is a network entity that acts as a
gateway between the ASN and CSN. The ASN functions hosted in an ASN-GW may
be viewed as consisting of two groups - the decision point (DP) that provides control
functionality and enforcement point (EP) that provides bearer transport.
AU Access Unit
AWG An electronics industry acronym for American Wire Gauge. AWG is a measure of the
thickness of copper, aluminum and other wiring.
BTS Base Transceiver Station. A wireless network element that provides the radio
interface of the network. The BTS comprises the radio transmission and reception
devices, and also manages the signal processing related to the air interface.
BW Bandwidth
CINR Carrier-to-Interference plus Noise Ratio (expressed in dB)
CIR Committed Information Rate. The rate (in bits per second) at which a network
guarantees to transfer information under normal conditions, averaged over a
minimum increment of time.
CLI Command Line Interface. A user interface that accepts typed commands to instruct
the managed device on the task to perform.
CPU Central Processing Unit.
CS Convergence Sublayer. Particular protocols that are responsible for gathering and
formatting higher layer information so it can be processed by the lower layers.
