3.0 IRCU Specification
For IRCU specification please refer to IRCU Datasheet IRCU.
IRCU tilting angle with adjustment accuracy of ± 0.1 °.
4.0 RET System and Working Principle
4.1 RET System
Remote Electrical Tilt (RET) system consists of two major part, electrical tilt enabled antenna and
controller.
4.2 Working Principle
IRCU obtains control information or number of motor rotation pulse throughout calibration. By
adjusting the motor rotation of IRCU, it is able to gain movement control of the phase shifter in
an antenna, and thus able to control antenna electrical tilt angle. While maintaining real time
communication between IRCU and PCU (Portable Control Unit), PCU send control command to
IRCU; IRCU will return the control result to PCU, and PCU act as Human-Machines interface.
