What is wireless USB technology?

Wireless USB is a term that can refer to any of several technologies that use a computer’s USB ports for wireless LANs.

Wireless USB over UWB

Certified Wireless USB is an industry standard for USB wireless networks based on ultra-wideband (UWB) signaling technology. Computer peripherals enabled with certified wireless USB interfaces connect and communicate wirelessly with a standard USB port on a computer. Certified wireless USB can support data speeds of up to 480 Mbps (megabits per second).→ See also – Wireless USB from the USB Implementers Forum (usb.org)

Wi-Fi Wireless USB Adapters

External Wi-Fi adapters are usually connected to the USB port of a computer. These adapters are casually called “Wireless USB,” even though the protocol used for signaling is Wi-Fi. Network speeds are limited accordingly; for example, a USB adapter for 802.11g can handle a maximum of 54 Mbps.

Other wireless USB technologies

There are also several wireless USB adapters that support alternatives to Wi-Fi:

  • Bluetooth
  • IrDA infrared
  • other proprietary signaling technology

Some examples of these products are Belkin Mini Bluetooth adapters and various Xbox 360 peripherals.
