Both Iogear and Wisair are showing UWB wireless USB hub technology which they claim will be capable of transmitting up to 480 Mbps, enabling up to four simultaneous wireless connections to such high-bandwidth devices as printers, scanners, and external hard drives. The setup is not entirely wireless: Peripherals are attached to the UWB hub by ordinary USB cables, though the hub connects to a notebook computer through a pre-paired USB adapter dongle.
