Free-Space Optics (FSO) is a technology that uses light to transmit data through the air, rather than through cables. It employs lasers or light-emitting diodes (LEDs) to send information over distances, making it a viable option for wireless communication. FSO can achieve high data rates and is often used in situations where traditional wired connections are impractical. One of the main advantages of FSO is its ability to provide high-speed internet connections without the need for physical infrastructure. However, its performance can be affected by environmental factors such as rain, fog, or obstacles like buildings. Despite these challenges, FSO remains a promising solution for various applications, including telecommunications and military communications.
