In March of 1998, Extended Systems first introduced short-range wireless connectivity to the Palm platform with Infrared Data Association (IrDA)-compliant communications for Palm III® and later devices. IrDA infrared is the most efficient wireless means of making fast data transfers and establishing ad-hoc connections between one device and another. Bluetooth complements IrDA infrared's point-and-shoot strength with omni-directional signaling, longer distance communications, and capacity to penetrate solid objects.
