Unguided Wireless Media: Here information is transmitted by sending electromagnetic signals through free space and hence the name unguided media, as the signals are not guided in any specific direction or inside any specific medium. All unguided media transmission are classified as wireless transmission.


Key Differences Between Guided and Unguided Media. The key difference between guided and unguided media is that guided media uses a physical path or conductor to transmit the signals whereas, the unguided media broadcast the signal through the air. The guided media is also called wired communication or bounded transmission media.


With guided transmission media, the waves are guided along a physical path; examples of guided media include phone lines, twisted pair cables, coaxial cables, and optical fibers. Unguided transmission media are methods that allow the transmission of data without the use of physical means to


Transmission media is also called Communication channel. Types of Transmission Media. Transmission media is broadly classified into two groups. Wired or Guided Media or Bound Transmission Media: Bound transmission media are the cables that are tangible or have physical existence and are limited by the physical geography.


Bounded or Guided Transmission Media in Computer Networks is the transmission media in which signals are confined to a specific path using wire or cable. In this tutorial we will learn about bounded transmission medium in details.


Guided Media: Guided media, which are those that provide a conduit from one device to another, include twisted pair cable, coaxial cable, and fiber-optic cable. A signal traveling along any of these media is directed and contained by the physical limits of the medium.

Guided media is a wired transmission media, in which data signals are guided along a physical path i.e. within a wire. Guided transmission media is also known as Bounded or wired. Some well-known Guided Transmission media includes Twisted Pair Cable, Coaxial cable, fiber optic cable, etc.


The first type is called bound transmission media or guided media. It uses physical links, such as coaxial or fiber optic cables, to transmit data to the desired connection. Most cables are made of copper and bound by some form of jacket material. Because they are tangible, this type of media is limited to a fixed location.


In guided media, electrical signals are confined within the cable or wire which transmits them. Typical forms of guided media include copper co-axial cables, fiber-optic cables and twisted-pair copper cables, which can be shielded or unshielded. Guided media are also sometimes known as bounded media.
