The adapter uses a USB 1.1 interface, which provides a high-speed connection to the computer. It also has a low power consumption, making it energy-efficient and suitable for use with battery-powered devices.

Long before Bluetooth and Wi-Fi became universal standards for wireless communication, there was Infrared Data Association (IrDA). This technology used beams of infrared light to transfer data between devices, much like a TV remote control. For nearly two decades, IrDA was a standard feature on countless laptops, PDAs (Personal Digital Assistants), and mobile phones.
