IrDA infrared communication is an inexpensive and widely adopted short range wireless technology that allows devices to “speak” easily to each other. Key protocol features make operation simple even for inexperienced users or devices with very little user interface. Digital cameras, phones, pagers, data collectors, set-top boxes, modems, kiosks, instruments, machinery, ID badges, watches, and computer peripherals are some of the natural users of this technology.

Infrared has long been used as a transmission medium for TV/VCR controllers, calculators, printers, and PDAs. In late 1993 an industrial group spearheaded by HP, IBM, and Sharp was founded to promote an industrial standard for Infra-red communications. A short two and half years later, this group, the Infra-red Data Association, has grown to 130 members strong. The membership are international and include component manufacturers, OEMs, hardware and software companies among others and new members coming every day.

Infrared Data Association (IrDA) is a non-profit trade association. It was formed to enable universal point and shoot infrared connectivity between devices of all types. Today there are hundreds of devices that implement IrDA communication protocols and the dream of ubiquitous data transfer is becoming more of a reality.

IrDA(TM) is an industrial standard, a set of specifications for providing a universal two-way wireless infrared data communications, based on a practical cost, short-range point-to-point user model. The standard defines the physical characteristics of the interface, the communications protocols that provide for diferent needs, and the transmission speeds at which the infrared device communicates. Unlike the earlier IR predecessors, which use proprietary protocols, this new crop of IrDA compliant equipments are inter-operative across applications, across manufacturers, and across platforms.
