Abbreviated as “WUSB” this short-range, high-bandwidth wireless radio communication combines the speed and ease-of-use of USB 2.0 with the expediency of wireless technology and is based on the WiMedia Alliance’s Ultra-WideBand (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters. However USB Implementers Forum discourages the practice of calling it WUSB and prefers to call the technology “Certified Wireless USB” to differentiate it from competitors (see below, “Competitors”). Though local regulatory policies may restrict the legal operating range for any given country, Wireless USB was designed to operate in the frequency range of 3.1 to 10.6 GHz.


WUSB are used in devices that are now connected via regular USB cables, such as game controllers, printers, scanners, digital cameras , MP3 players, hard disks and flash drives , and it is also suitable for transferring parallel video streams.
