AAT - Antenna Array Tool -
Software tool for embedding antenna parameters and radiation
patterns in test scenarios.
ACLR - Adjacent Channel Leakage Ratio -
The ratio of the transmitted power on the assigned channel to the
power received on the adjacent channel after passing through a root
raised-cosine filter.
ACP - Adjacent Channel Power -
The power contained in a frequency channel next to the
specified channel.
ACPR - Adjacent Channel Power Ratio -
The ratio of the power contained in a specified frequency
channel bandwidth relative to the total carrier power.
AM Distortion -
Undesirable distortion caused by amplitude variation in a
communications system.
AM/PM Distortion -
Undesirable distortion that causes signal degradation in
a communications system, typically as the result of the
interaction between an amplifier’s phase response and the
power level (or amplitude) of the input signal.
AMF - Access And Mobility Management Function -
A component of the 3GPP core network architecture that
manages user equipment registration, authentication,
identification, and mobility. AMF also terminates non-access
stratum signaling.
Antenna Reciprocity -
A theory that states that the transmit properties of an antenna
will be identical to the receive properties of that antenna in a
given medium.
AUSF - Authentication Server Function -
A major component of the 5G core network used to facilitate
security processes. The AUSF authenticates UEs and stores
authentication keys.
AWG - Arbitrary Waveform Generator -
Electronic equipment used to generate signals for injection into
a device under test (DUT) to characterize its performance.
AWS - Advanced Wireless Services -
Wireless spectrum band used to transmit data and voice services. It uses frequencies 1700 MHz for uplink and 2100 MHz for downlink
