USB3.0 - with Lack of support for it from Intel, It may be a while before
we see this 4.8Gbps. **broken link removed**
Wireless USB - With UltraWideBand (UWB) technology almost dead,
it will interesting to see this 480Mbps wireless speed.
(Wireless USB is the only spec that is using UWB , while
all others have shifted to 60GHz camp).
In the meantime, Intel is pushing its own Proprietary Technology
called Light Peak (Optical fiber based)
**broken link removed**
That's Intel! That says something , but does something else!.
USB3.0 include Super Speed and usb2.0(HS/FS/LS). For physical layer of SS, it is PIPE interface compliant and it uses differential signal (TX+/TX-, RX+/RX-) to transfer signal.
For link layer of SS, it uses link command to do link flow control and power saving.
For protocol layer, it is similar with usb2.0.
