You modulate them (AM, FM, pulse mod, phase mod, etc)
same as any other e-m radiation.
The human brain does not perceive infrared waves directly. Infrared radiation is detected by specialized sensors or cameras that can then convert the signals into a form that the brain can interpret, such as images or data. Metal objects reflect infrared waves differently than other materials due to their properties, and this information can be used for various applications like thermal imaging or object detection.
Radio waves are the type of electromagnetic wave that carries television and radio signals. They have longer wavelengths than microwaves and shorter wavelengths than infrared waves.
Infrared waves are a type of electromagnetic waves that carry infrared radiation. Infrared radiation is a form of energy that is emitted or absorbed by objects as heat. Infrared waves have longer wavelengths than visible light and are commonly used in devices such as remote controls and infrared cameras.
No, cellular phones do not use infrared waves for wireless communication. They typically use radio waves to connect to cellular networks and communicate with other devices. Infrared technology is more commonly found in remote controls and certain types of data transfer technologies.
Infrared waves are used for communication by encoding data onto them and transmitting it wirelessly. Devices such as remote controls, IR blasters, and infrared transmitters emit infrared light beams carrying information to be received and interpreted by a compatible device. These waves are typically used for short-range communication within a limited line of sight.

Devices such as remote controls, IR blasters, and infrared transmitters emit infrared light beams carrying information to be received and interpreted by a compatible device. These waves are typically used for short-range communication within a limited line of sight.
Infrared waves give off more energy because they have longer wavelengths compared to visible light and ultraviolet waves. This longer wavelength means that each photon of infrared radiation carries less energy, but there are more photons present per unit of energy, leading to higher overall energy output.
Infrared waves are used for a variety of purposes, including thermal imaging, night vision technology, remote controls for electronic devices, and infrared heating systems. They are also used in communication systems like infrared data transmission and in some medical applications for pain relief and muscle therapy.
Infrared is a much longer wavelength than ultraviolet.
Infrared can be used to communicate information by encoding data onto infrared light waves and transmitting them wirelessly between devices. The devices typically have infrared transmitters and receivers that can emit and detect the modulated infrared signals, allowing for data transfer such as remote control commands, data sharing, or proximity detection.
They most use infa red but they use wireless for the more recent technology.
Infrared & Microwaves are used to carry information through Optical Fibres. Infrared carries visible light Radio Waves & Microwaves carry telephony and computed data E.Akbay
