(IrDA) A non-profit trade association providing standards to ensure the quality and interoperability of infrared (IR) hardware.
The association currently has a membership of over 160 companies from around the world, representing computer and telecommunications hardware, software, components and adapters.
IrDA typically uses direct infrared i.e. point-to-point, line-of-sight, one-to-one communications. The standards include: IrDA Data (SIR, FIR, VFIR), IrDA Control, and AIR.
Ports built to the above standards can be found in products such as PDAs, Palm devices, printers, desktop adapters, notebooks, and digital cameras.

- Infrared radiation
infrared radiation [(in-fruh-red)] Invisible radiation in the part of the electromagnetic spectrum characterized by wavelengths just longer than those of ordinary visible red light and shorter than those of microwaves or radio waves. (Compare ultraviolet radiation.) Note: The heat we feel from a glowing coal or an incandescent light bulb is from infrared rays.
