1. Overview
AICM (Air Interface Control Module) is an antenna control unit for performing Electrical beam
tilting, beam width control, mechanical steering. In order for communicating with AICM
management server, it supports Ethernet and RS-485/422/232 Serial interface and conducts
antenna reset, status monitoring, and antenna beam control. It also provides direct user interface
for installation and maintenance. It can accommodate up to 3 antennas. Besides, AC power input,
antenna VSWR monitoring, AMA support are also supported as features.
* AMA (Antenna Mounted Amplifier) is the same as TMA (Tower Mounted Amplifier).
