It can be run for hundreds of miles without the need for signal repeaters, in turn, reducing maintenance costs and improving the reliability of the communication system because repeaters are a common source of network failures. This term can apply to both guided and unguided media. The signal is broadcasted through air or sometimes water.

The signals transmit between communicating devices in the form of electromagnetic energy, and hence the signals are called electromagnetic signals. The unguided media is a wireless communication it guided and unguided transmission media signal by broadcasting it through the air.

Radio waves frequency are easy to generate, can travel long distances, and can penetrate buildings easily, so they are widely used for communication, both indoors and outdoors. The unguided media is categorized into radio waves, microwaves and infrared waves.

Wireless transmission can be used as the medium in both LAN and WAN environments, as illustrated in the diagrams below:. Microwaves are unidirectional, when an antenna transmits microwaves they can guided and unguided transmission media narrowly focused.

Guided media is a wired communication it transmits data either using twisted pair cable, coaxial cable or fibre optics; it requires maintenance charge. The microwaves are transmitted in a straight line and hence require the line-of-sight transmission. This page was last edited on 18 Juneat Guided transmission media are more commonly known as the wired communication or bounded transmission media. Like, the remote control for televisions, VCRs, etc. The term direct link is used to refer to the transmission path between two devices in which signals propagate directly from transmitters to receivers with no intermediate devices, other than amplifiers or repeaters used to increase signal strength.

These signals are available to one who has the device capable of receiving those signal.

Thus, an optical fiber or a copper cable is a transmission medium. Another example of a physical medium is optical fiberwhich has emerged as the most commonly used transmission medium for long-distance communications.

Many transmission media are unguiced as communications channel.

What are Guided and Unguided media? | Computer Networking Demystified

Good information but not clear explanation about types of unguided media…. Your email address will not be published. Since the towers with the mounted antennas needs to be in direct sight of guided and unguided transmission media other, towers that are for apart need to he very tall, the curvature of the earth as well guided and unguided transmission media other blocking obstacles do not allow two short towers to communicate using microwaves, Repeaters are often needed for long distance communication very high frequency microwaves cannot penetrate walls.


Optical fiber for indoor applications cost approximately a dollar a foot, the same as copper.

Difference Between Guided and Unguided Media (with Comparison Chart) – Tech Differences

Infrared waves unguuded used for short range communication. It is primarily used in cable TV networks and as trunk lines between telecommunication equipments. Notify me of follow-up comments by email.

Types Twisted pair cable, coaxial cable and fibre optic cable. The diagram given below illustrates different types of antennaes typically used in wireless communication.

What are Guided and Unguided media?

A pair of antennas can be aligned without interfering with another pair of aligned antennas. Notify me of new posts by email. Please help improve it to make it understandable to non-expertswithout removing the technical details.

Guided Media or Wired links: January Learn how and when to remove this template message. For biological transmission, see Vector molecular biology. Really very helpful notes, helped me thank you so much. The guided media is guided and unguided transmission media further into three categories that are twisted-pair cable, coaxial cable and fiber-optic cable.
