Detailed explanation-1: -Infrared communication requires a transmitter and a photoreceiver to receive the light beam. Since any disruption to the light will result in the photoreceiver not receiving it, IR will only function when there is a line of sight visibility.
Detailed explanation-2: -FM radio, microwave and satellite transmission are examples of line-of-sight communication.
Detailed explanation-3: -Infrared. Most infrared sources transmit using an LED or laser. The infrared technology that underlies most remote controls only works across a straight, short, unobstructed path between the remote and the device.
Detailed explanation-4: -Microwaves use line-of-sight transmission. To avoid possible obstructions, such as buildings or mountains, microwave stations often sit on the tops of buildings, towers, or mountains.
Detailed explanation-5: -Infrared. Infrared communication uses invisible to the naked eye infrared light rather than radio waves. It is only used for short-range communication and requires a line of sight between the two devices (because light does not readily penetrate solid objects such as walls, unlike radio waves).
