For biological transmission, see Vector molecular biology. Even satellites act as giant antenaes in the sky, by receiving and transmitting signals generated from the earth. A guided and unguided transmission media medium in data communications is the transmission path over which a signal propagates. Electromagnetic signals are the ynguided of electric and magnetic fields that vibrates in relation to each other.

Different Types of Antennaes Used in wireless communication. Due to this, fiber optics communication supports longer distances as there is no electrical interference.

Examples mediq Wired Media.

Different forms of wireless communication used in the internet vary mainly based on the following attributes: As the guided and unguided transmission media indicates, fiber optic cables are made of very thin strands of glass silica.

The microwaves are transmitted in a straight line and hence require the line-of-sight transmission. Four major factors favor optical fiber over copper- data rates, distance, installation, and costs. In unguided media, the electromagnetic signals are broadcasted through air to everyone.


In the latter case, the medium is carrying signals in both directions at same time. The signal is broadcasted through air or sometimes water. For example, the transmission medium for sounds is usually a gas, but solids and liquids may also act as a transmission medium for sound.

What are Guided and Unguided media?

These telephone lines are reused as last mile DSL access links to access the internet from home. Since the towers with the mounted antennas needs to be in direct sight of each other, guided and unguided transmission media that are for apart need to he very tall, the curvature of the earth as well as 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.

Radio wave, microwave and infrared. Hope other readers too see this explanation. 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.

However, the unguided media is also called wireless communication or unbounded guided and unguided transmission media media. Leave a Reply Cancel reply Your email address will not be published.

Difference Between Guided and Unguided Media

More the taller are antennas longer is guided and unguided transmission media distance covered by the signal. Good information but not clear explanation about types of unguided media…. The diagram given below illustrates different types of antennaes typically used in wireless communication.


Like, the remote control for televisions, VCRs, etc. Examples of this include microwaveradio guidfd infrared. The microwave has a frequency higher than the radio waves.

Transmission medium – Wikipedia

This term can apply to both transmiission and unguided media. It serves as an internet access line from the home. The twisted pair cable has two conductors wires wounded around each other and each surrounded by an insulating material. In simplex transmission, signals are transmitted guided and unguided transmission media only one direction; one station is a transmitter and the other is the receiver. Wireless media may carry surface waves or skywaveseither longitudinally or transverselyand are so classified.

Alternative name It is called wired communication or bounded transmission media.

The distance covered by the microwave signal depend on the height of the two antenna. Sound is, by definition, the vibration of matter, so it requires a physical medium for transmission, as do other kinds of mechanical waves and heat energy. Categories of guided media are twisted pair cable, coaxial cable and optical fibre.

Glass guided and unguided transmission media lighter than copper allowing for less need for specialized heavy-lifting equipment when installing long-distance optical fiber. A transmission medium is a material substance solidliquidgasor plasma that can propagate energy waves. They are relatively directional, cheap, and easy to build but have a major drawback:
