Unguided/Wireless Media Ways Of Transmit Signals Radio Communication Band Satellite Transmission Laser/Light Wave Transmission Wireless media transports electromagnetic waves without using a physical conductor. Features of Unguided Media 1)Have no guide or direction for transmission of signals or electromagnetic waves. It consists of the following components: Transmitter Receiver Atmosphere The microwave has a parabolic antenna mounted on towers to send a beam to other antennas which are tens of kilometres away. The guided media formed the different network topologies. The unguided media is classified into radio waves, microwaves, and infrared waves. Magnetic Media Magnetic media is a common and oldest method to transport information from one computer to another computer which is still being used. Presentation On Computer Network Topic:-Transmission Media Subtopic:-Guided Media Unguided Media Submitted to:- Submitted by:- 2)The data signals can flow freely 3)It does not bound to a specific or particular channel. . Communication channels are those channels which are used to transfer data from one computer to another in a network. Transmission media are the physical pathways (guided or unguided) that connect computers, other devices, and people on a network. The microwaves are transmitted in a straight line and consequently require line-of-sight transmission. b) Satellite: A satellite is an amplifier or repeater that receives information from one location on the earth, repeats the data, and sends it to one or more receiving locations on the earth. Unguided media transport electromagnetic waves without using a physical conductor. In data communication, the transmitter sends the signals, and the receiver receives them. The key difference between Guided Media and Unguided Media is that in guided media, the signals travel through a physical medium while in unguided media, the signals travel through the air. Proper shielding of guided media is required to reduce the interference issue.
