Terminology I
IrDA -
IrDA is an infrared wireless communication technology developed by the Infrared Data Association. IrDA is a specific use of infrared light as a communications medium. The IrDA specifies hardware and software protocols for wireless communication intended to promote interoperable applications. Because infrared uses the nonvisible infrared light spectrum, IrDA communication is blocked by obstacles that block light (such as walls, doors, briefcases, and people). The initial IrDA data rate of 115 kilobits per second (Kbps) has now been enhanced to 1 megabit per second (Mbps).
Terminology B
Bluetooth -
Bluetooth technology is a specific use of radio waves as a communications medium. The effective range for Bluetooth wireless communication is about 10 meters using the standard 0 dBm radio. With optional power amplification of up to 20 dBm, range on the order of 100 meters can be achieved.
