What is FSO?

Free space optic (FSO) communication is a line-of-sight technology that uses infrared (IR) light through the atmosphere to provide wireless connectivity between two points. In comparison to radio frequency (RF) counterparts, the FSO link has a very high optical bandwidth available, allowing much higher data rates on the order of Gigabits per second (Gbps). Since FSO systems use very narrow laser beams, the resulting spatial confinement provides a high reuse factor and an inherent security. Furthermore, their deployment does not require license fees since they operate in the IR optical band which is unregulated worldwide.
