Wireless USB

Wireless USB or WUSB abbreviated (Calling from USB Implementers Forum: Certified Wireless USB) is an extension to the wireless USB equipped with high-bandwidth, short range, combining the speed of USB 2.0 devices with the convenience of technology wireless.
Wireless USB is based on the modulation of the WiMedia Alliance Ultra-wideband, with a theoretical bandwidth of 480Mbit / s over a distance of 3 meters and 110Mbit / s up to 10 meters.
Operates between 3.1 and 10.6 GHz frequency communication and spreads across the spectrum according to the ultra wideband modulation.
In mid-2007 were presented some devices 'Certified Wireless USB', compliant WiMedia PHY 1.1 and 1.0 MAC, operating between 3.1 and 4.8Ghz, such as the Dlink DUB-1210 (adapters) and its DUB-2240 (the wireless hub ), or the Belkin F5U302 (which includes, bundled, the adapter and the hub).
In late 2007 we are developing the Wireless USB 1.1 specifications

Typically the architecture communicates via USB cable and master / slave, ie where 'USB host' (implemented on computers) acts as the master and the 'USB slave' devices placed on acts precisely as a slave. Only the USB host can 'manage communication and data transfer link. However, there are variations such as the so-called USB On-The-Go to address, only a few cases, this issue. Or you use the USB Hub.
In 'Wireless USB architecture, a WUSB device can support the DDR (Dual-Role Device), which itself can function as a host, but with capacity' limited. So you do not need a hub to communicate with each other peripherals.
Currently, however ', also to facilitate the use of "real" USB devices in a wireless environment, were introduced two classes of products. The Device Wire Adapter (DWA) and Host Wire Adapter (HWA).
The DWA are commonly called WUSB Hub and Wireless USB hub, as conceptually similar to the 'USB Hub', which allow you to connect multiple USB devices classic, and simultaneously act as a wireless UWB transmitter, thereby to 'bridge' between the wired world and wireless.
The HWA are wireless adapters, typically with USB interface (or Express Card), to be connected to the computer, performing function 'and not by WUSB host.
