PERFORMANCE
The Wireless USB adapter set is based on Ultra-wideband technology, which is a personal area network (PAN) technology, designed to provide wireless coverage in the range of 10 meters (30 feet). As such, the adapter set provides full room coverage, both with line of site and with no line of site (note that it is not designed to operate across rooms). This allows you to locate USB devices in the room without the limitation of the USB cable length.
To test performance, the adapter set was used in a large meeting room measuring 10x4 meters (30x12 feet). The laptop and PC adapter were placed in one side of the room, and each time a different device was placed in the other side of the room. To verify line of site, and non-line of site behavior, devices were sometimes placed on a shelf or within a closet, and people were sitting and passing within the wireless link. Performance was not affected by increasing the range, or by a lack of line of site between adapters.

Link establishment was tested by exiting the room with the laptop to intentionally break the wireless link between the notebook and an external hard disk drive. Then, once returning to the room, the wireless link was automatically re-established, enabling connectivity to the hard drive, without requiring any involvement. This simulates a common scenario where your notebook is connected to a peripheral device and you leave the room with the notebook, returning after a while. With wired USB you have to disconnect and connect devices, while with Wireless USB the adapter set automatically re-connects you to the device once back in range, with no further action.
