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 or an optical transmission line. The technology is useful where the physical connections are impractical due to high costs or other considerations.
Typically, best use scenarios for this technology are:
LAN-to-LAN connections on campuses at Fast Ethernet or Gigabit Ethernet speeds
LAN-to-LAN connections in a city, a metropolitan area network
To cross a public road or other barriers which the sender and receiver do not own
Speedy service delivery of high-bandwidth access to optical fiber networks
Temporary network installation (for events or other purposes)
Reestablish high-speed connection quickly (disaster recovery)
As an alternative or upgrade add-on to existing wireless technologies
Especially powerful in combination with auto aiming systems, this way you could power moving cars or you can power your laptop while you move or use auto-aiming nodes to create a network with other nodes.
As a safety add-on for important fiber connections (redundancy)
For communications between spacecraft, including elements of a satellite constellation
For inter- and intra -chip communication.
The light beam can be very narrow, which makes FSO hard to intercept, improving security. In any case, it is comparatively easy to encrypt any data traveling across the FSO connection for additional security. FSO provides vastly improved electromagnetic interference (EMI) behavior compared to using microwaves.
Ease of deployment
Can be used to power devices
License-free long-range operation (in contrast with radio communication)
High bit rates
Low bit error rates
Immunity to electromagnetic interference
Full duplex operation
Increased security when working with narrow beam(s)
No Fresnel zone necessary
