What is unguided transmission in the context of data communication?

Unguided transmission, also known as wireless transmission, refers to the method of sending data without the use of physical media such as cables or fibers. This type of transmission utilizes electromagnetic waves to propagate data through the air or space. Examples of unguided transmission include radio waves, microwaves, and infrared communication. In unguided transmission, data is transmitted over the air or through space, relying on radio frequencies, microwaves, or other forms of wireless signals. This method contrasts with guided transmission, where data is sent through physical media like cables or optical fibers. Unguided transmission is essential for mobile communication, satellite communication, and Wi-Fi networks, allowing for greater flexibility and mobility in data communication.
