Wireless 1 Radio

The Infrared Data Association, or IrDA, is a consortium of device manufacturers had developed a standard for transferring data via infrared light waves.

Many portable devices, such as laptops and Personal Device Assistants (PDAs), are increasingly using IrDA ports.

Two IrDA enabled devices can easily transmit data between each other as long as there's a clear line of sight between the devices, and they are in close proximity to each other.

Current IrDA technology can achieve transmission speeds close to that of the standard parallel port (12 Mb per second).

As for peripheral devices, they're commonly limited to the low bandwidth devices such as keyboards, mice, and printers.
