1.3 Smart-ALC Function
The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for automatic repeater
gain adjustment. Combined with advanced control algorithms, SALC is capable of learning the traffic
load characteristics and adjusting the Repeater RF Gain to the desired value.
Smart ALC eliminates the need to perform initial settings for maximal traffic load conditions and on-
site gain adjustments.
Smart-ALC maintains the Uplink/Downlink gain balance for system transparency. In addition, Smart-
ALC prevents oscillations that may occur due to insufficient isolation while maintaining the gain in a
linear range operation by adjusting the repeater paths’ gain accordingly.
IMOP (Isolation Measurement and Oscillation Prevention) algorithm effectively reduces oscillation
problems.
The repeater’s power amplifier includes power-monitoring circuits with Automatic Level Control
(ALC) that prevents excessive output power while maintaining the power amplifier linearity.
