Infrared technology offers several important advantages as a form of wireless communication
1. Low power requirements: therefore ideal for laptops, telephones, personal digital assistants
2. Low costs for the coding/decoding circuitry.
3. Simple circuitry: no special or proprietary hardware is required, can be incorporated into
the integrated circuit of a product
4. Higher security: directionality of the beam helps ensure that data isn't leaked or spilled to
nearby devices as it's transmitted
5. Portable
6. Few international regulatory constraints: IrDA (Infrared Data Association) functional
devices will ideally be usable by international travelers, no matter where they may be.
7. High noise immunity: not as likely to have interference from signals from other devices.
