WUSB is Wireless USB a high-bandwidth wireless extension to USB which is short-range so also known as WUSB. WUSB combines the speed of USB 2.0 of 480Mbit per second with the convenience and ease of wireless technology. WUSB is the most common terminology used for Wireless USB but the Implementers Forum or USB-IF would rather you say Certified Wireless USB, but who’s got time for that.
WUSB is based off the WiMedia Alliance’s Ultra-WideBand (UWB) radio platform which means WUSB will work at the 480Mbit/s speed up to 9 feet away and then slow down to 110Mbit/s with a max range of 30 feet. WUSB works on the 3.1 to 10.6 GHz frequency range and spreads communication over an ultra-wideband of frequencies.
With USB now in over 2 billion USB gadgets, peripherals and electronic devices to cut the cable and introduce WUSB is a welcome thought.
Just incase you didn’t know, USB is an acronym for Universal Serial Buss.
