Security: Infrared communication has high directionality and can identify the source as different sources emit radiation of different frequencies and thus the risk of information being diffused is eliminated.Example is the wireless LAN communication system Diffuse Point: It doesn’t require any line of sight and the link between the transmitter and the receiver is maintained by reflecting or bouncing of the transmitted signal by surfaces like ceilings, roof, etc.Example is the remote control communication. In other words the transmitter and the receiver should be pointed to each other and there shouldn’t be any obstacles between them.
