NOTE
l An AAU contains built-in remote control units (RCUs).
l An RCU is a driving motor used for the phase shifter in the RET antenna. It receives control commands
from a base station and runs commands to drive the stepper motor. Using a gear, the stepper motor
drives the adjustable phase shifter in the antenna to change the downtilt of the antenna.
