Free-space optical communication, also known as optical wireless communication, is a method of transmitting data using light as the carrier wave through open air. This technology uses laser or LED light to transmit data between two points without the need for physical cables or wires. Free-space optical communication is commonly used for high-speed data transfer in situations where traditional wired communication is not feasible, such as in remote areas or for point-to-point communication over short to medium distances. This technology has the advantage of being able to transmit data at very high speeds, but is limited by factors such as weather conditions, obstructions in the line of sight, and atmospheric interference.
