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. This contrasts with using solids such as optical fiber cable . Due to the LOS requirement, the distance of light propagation through free atmospheric space is from hundreds of meters up . Abstract: Wireless networking has conventionally been realized via radio frequency (RF) based communication technologies.
However, the capacity of these networks are limited by the availability of the RF spectrum.

Currently, FSO is capable of up to 2. Gbps of data, voice and video communications through the air, allowing optical connectivity without requiring fiber-optic cable or securing spectrum licenses.

In FSO communications, optical transceivers communicate directly through the air to form point to point line of sight links. The transmitter converts the electrical signal to an optical one and sends it through the atmosphere ( free space ). FSO) communication and its connectivity with central. The receiver converts the optical signal back to an electrical signal.
BOROSON, MIT LINCOLN LABORATORY. Heuristics were developed for ring networks (optical transceivers per node) as well as for 3-degree networks (optical transceivers per node). Optical wireless, also known as free space optics (FSO), is an effective high bandwidth communication technology serving commercial point-to-point links in terrestrial last mile.
Free - space laser communication works by transmitting laser light through the air between transceivers spaced several hundred meters to several kilometers apart. Terrestrial Free丁Space Optical Communications.
