free-space optical communication
Free-space optical communication (FSO) is a technology that uses light to transmit data through the air. It involves sending modulated light signals, typically from lasers or LEDs, between two points without the need for physical cables. This method can provide high-speed data transfer over short to medium distances, making it useful for applications like internet connectivity and satellite communication.
FSO systems are often used in environments where traditional wired connections are impractical or too costly. They can operate in various weather conditions, although heavy rain or fog may affect performance. Overall, FSO offers a flexible and efficient way to communicate wirelessly.
