60GHz is where WiGig lives, an internationally unlicensed band where there's plenty of space but propagation is poor. WiGig is proposed as the next generation of Wi-Fi, offering vastly improved speeds, so the USB Implementers Forum will be porting USB 2 and 3 to run right on top of it.USBs will now be able to use any kind of wireless system, including WiGig, Wi-Fi and ultrawideband.Until now, the best hope of wireless USB was ultrawide band (UWB) radio – also used in "see-through-the-wall" radar-imaging techniques. UWB uses a low-powered signal across a massive range of frequencies – reminiscent of the interference generated by an electric drill or similar. The bands are full of other stuff, but the UWB signal isn't powerful enough to interfere. It is, however, powerful enough to carry a 480Mb/sec connection.
