About IrDA

Infrared technology is not new.  The remote control we use to change channels on our TV uses infrared.  It does its job well because it does not need to communicate with any other device and it does not need to be fast.  After all, changing channels or adjusting volume on your TV is merely simple one-way command transmission.

What makes IrDA infrared different1 from standard TV infrared or infrared keyboard is that IrDA is now a standarized protocal that enables data transfer between 2 different devices in relatively high speed. Essentially, any PC, peripheral, or portable electronics equipped with an IrDA infrared port can transfer data in high speed to each other.

IrDA stands for Infrared Data Association.  It is founded on 1993 to develop a set of hardware and software standards that allow for the transfer of data between two devices using infrared. The original IrDA standard, called IrDA 1.0, allowed for the transfer of data at up to 115.2kbps (kilobits per second) at a range of up to 1 meter (about 3 feet) plus or minus 15 degrees. In 1996 an extension to this standard was adopted (called IrDA 1.1) which allowed for data transfers up to 35 times faster than the original specification. This extension calls for data rates up to 4Mbps (megabits per second) but retains compatibility with the original (115.2kbps) specification.  Achieving the 4Mbps transfer rate not only requires all hardware involved to be IrDA 1.1 complaint, but the software that is running to facilitate the data transfer may need to be modified to support the extension.

Currently, IrDA members include most major companies including all of the major computer, telecommunications, printer, and PDA companies in the world such as,

3COM, Acer, Alpha Peripherals, AMP, Apple Computer, Canon,  Casio Computer, Citizen Electronics, Citizen Watch, CMD Technologies, Compaq Computer, Dell Computer, Eastman Kodak, Ericsson, Fuji Photo Film, Fujitsu, Funai Electric, Hewlett-Packard, Hitachi, IBM, Intel, Inventec, JVC, Kawasaki Steel, Linux-IrDA Project, Logitech, Matsushita/Panasonic, Microsoft, Minolta, Mitsubishi, Motorola, National Semiconductor, NEC, New Japan Radio, Nokia,  NTT DoCoMo, NTT/Nippon Tel & Tel, Philips, Phoenix Technologies, Ricoh, ROHM, Sanyo, Scientific Atlanta, Sharp Electronics, Sony, , Texas Instruments, Toshiba, USB, Winbond, ZiLOG ...... etc.
As with most successful technologies, IrDA infrared port equipped products are growing rapidly.  Currently, virtually all notebooks and Palm PCs are equipped with an IrDA port.  Even non-PC IrDA equipped devices are growing rapidly including:

1. When a software application such as IrDA Remote Control is installed, some TV remote control units can be used to control your Infrared Drive equipped Media Player/Media Center based PC.
