Fast Restoration of Network with Remote Electric Tilt (RET) using IoT

Modern mobile communication networks need the possibility of managing and control the electrical down tilt of antennas remotely. As a result, most antennas need to be equipped with Remote Control Units (RCUs) to change the down tilt without physical involvement. Using standard remote electrical tilt equipment (RET) requires more time to shift the equipment near to the base station and are much costlier. With the help of RET equipment, technicians can adjust the beam pattern of antennas, RF power transmitted and intermodulation distortions without network shutdown. In this paper, the design and implementation of a low cost prototype remote control system for antenna tilt alignment is presented. In this work, Raspberry Pi board and servo motors based hardware mechanism for remote electrical tilting of antenna is described. To adjust the angular posservo motors controls the position of antenna unit PWM commands to the Raspberry Pi controller, the servo motors angular position can be controlled from a remote place through Ethernet or WI-Fi network.
