IrSimple

IrDA has adopted IrSimple specifications as their high-speed wireless communications protocol standards. IrSimple achieves faster data transmission speeds (at least 4 to 10 times faster than at present) by improving the efficiency of the current infrared IrDA protocol embedded in many mobile devices such as mobile phones. Incorporating IrSimple in digital consumer electronics devices and home appliances is expected to lead to a significant expansion in applications for this new communications protocol. For example, high-resolution photographs taken with a mobile phone or digital camera can be instantly transferred to a flat-panel TV or printer through a simple operation, similar to that of using a remote control unit.

Main Features of IrSimple

Faster data transmission speeds (at least 4 to 10 times faster than existing protocol Improved efficiency of the protocol by reducing latency until a receiver/transmitter pair is ready to communicate Implementing IrSimple can be done by adding and/or upgrading software for existing IrDA protocols Backward compatiblity with existing IrDA-enabled communications incorporated into devices or equipment Comparison with Existing System (IrDA Protocols) [Comparison of transfer times when transferring a 2-megapixel image (approximately 500K bytes)]

Protocol	IrSimple-4M protocol*1	IrDA-4M protocol*1	IrDA-115K protocol*2
Transfer time	Approx. 1 second	Approx. 4 to 11 seconds	Approx. 50 to 100 seconds

Notes: *1 Uses the FIR (Fast IrDA) specification for the speed of the physical layer (up to 4 Mbps).
*2 Uses the SIR (Serial Infrared) specification for the speed of the physical layer (up to 115.2 kbps). Currently incorporated in many mobile phones.
