Company Wisair has produced an industry first by now offering a wireless USB hub. Initially giving you a range of up to 30 feet in 2- or 4-port configurations, the Wireless USB Hub isn't as fast as standard USB 2.0, at around a quarter the speed. Both the press release and the info sheet on the Wireless USB standard don't mention particular power requirements, but if it works half as well as it sounds it would be a very interesting technology to have around the house. Unfortunately the device isn't finished yet and is only a reference model, but hopefully soon we'll see this in various configurations on the shelves.
