Free-space communication is a form of communication technology that enables the transmission of data or signals through the air or outer space without the need for physical cables or wires. This type of communication can be accomplished through various methods such as radio waves, lasers, or infrared signals. Free-space communication is commonly used in applications such as satellite communications, wireless internet, and deep space exploration. It offers the advantage of providing communication capabilities in areas where traditional wired networks are not feasible or practical. Research in this area focuses on improving the efficiency, reliability, and security of free-space communication systems.
