wireless USB

The wireless version of the universal serial bus (USB). Using ultra-wideband (UWB) technology, wireless USB is used to transmit the content of a laptop screen to a TV set or to a USB device that is within line of sight. Up to two meters (6.6 ft.), wireless USB provides the same data rate as USB 2.0 (480 Mbps). Within 10 meters (33 ft.), it reduces to 110 Mbps.

More Than Enough Connections
Wireless USB (WUSB) uses a hub and spoke architecture that provides up to 127 point-to-point connections. In 2004, the wireless USB Promoter Group was initiated at the Intel Developer Forum, which included HP, Microsoft and others. See USB, WHDI, WiGig and WirelessHD.


The First Wireless USB Hub
Introduced in 2006, the Belkin transceiver plugs into a USB port on a laptop, while the hub is cabled to four external USB devices, such as a hard disk, keyboard or printer. (Image courtesy of Belkin Corporation, www.belkin.com)







Stream to the TV
