Enhancing FSO/RF Link Performance Under Extreme Weather Conditions: A Novel Hybrid System with a High-Directivity Parabolic Reflector Antenna

Abstract

This paper introduces a novel design for a hybrid system FSO/RF composed by two subsystems. The first stage is a Free Space Optical FSO transmission subsystem and the second one is composed by a Radio Frequency subsystem terminated by an antenna. The main objective of this system is to face the exb vb treme weather conditions and assure its permanent operability. For RF subsystem a new antenna with high directivity is studied and designed. A comparison between different antennas with different materials is conducted to demonstrate the efficiency of the antenna in terms of its directivity and maximum gain. The RF subsystem acts as a backup, maintaining data transmission between transmitter and receiver when the optical channel degrades. In the moderate weather conditions the system can switch to the second subsystem composed by a 5G free space optical system. The hybrid communication system is investigated optimizing various parameters with the aim to address the vulnerability of the optical subsystem to climatic disruptions. The performance of various Scenarios is taken into account to improve the Q-Factor and Eye diagrams. The integration of a high-performance RF subsystem into the FSO system enhances the overall capabilities of the entire system. The results demonstrate satisfactory performance This paper introduces a novel design for a hybrid system FSO/RF composed by two subsystems.
