Add the IrDA standard for computers that do not have the standard used in many portable systems, such as mobile phones, PDAs, digital cameras, laptops, Pocket PCs, and so on. The IrDA standard is used for connection to infrared so you can easily connect devices with this standard to your PC. Avoid using different cables to connect multiple devices and concentrate these connections in the infrared. The utilities are many and depend on each device that has this type of port. The transmission speed of these devices reaches up to 4 Mbps and can transmit to a distance of 1m.
