Hybrid Free Space Optics (FSO)/Radio Frequency (RF) communication systems can improve the performance of Free space optical communications

Hybrid FSO RF communication system

Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. “Free space” means air, outer space, vacuum, or something similar. FSO operates on the Line-of-Sight…...
