UWB’s fate is pretty much tied to that of Certified Wireless USB, which is only communication protocol that still depends on the said radio technology. While there are already several WUSB devices, from video / audio adapters to hard drives and docking stations, on the market, the adoption rate is a far cry from that of other USB standards. The performance of these wireless peripherals is quite discouraging with real-world transfer rate averaging at just around 15MB/s. Native WUSB hosts can remove some overhead, and likely provide some speed boost, but significant improvement will only come with new specs, just like USB 3.0.
WiMedia Alliance, believed to be in the process of disbanding, has released version 1.5 of the common radio platform specs, which in a nutshell defines the foundation for Wireless USB. The upgrade now pushes speed from 480Mbps to 1024Mbps, doubling the available bandwidth for peripherals that stream 1080p video from a laptop to HDTV. Whether or not this will save WUSB remains to be seen, but the new specs certainly outpaces 802.11n in speed, yet slaughtered by upcoming WiGig 1.0 (7Gbps).
