WUSB: Wireless USB

No interference with Wi-Fi or Bluetooth
Wireless USB uses a short range radio modulation technology - Ultra Wide Band (UWB), which provides network transfer speeds that are higher over short distances and weaker signal strength, while providing the advantage of being able to easily traverse obstacles. Unlike Bluetooth or infrared connections, you don’t need to bring the devices close together to establish a connection, or even remove objects blocking the signal path. The frequencies used range from 3.1 to 10.6 GHz, which means there is no disruption or interference from Wi-Fi or Bluetooth which use the 2.4 GHz frequency range.

Gone are the numerous cables used to connect devices to the PC!
The advantage of WUSB is that you can get rid of numerous cables which are connected to the computer, most often via a USB hub. You generally need to connect at least a keyboard, mouse, monitor and external hard drive to the USB A ports, a screen to the DVI, HDMI or VGA ports, a printer on the USB B port and connections to the Ethernet and Digital 7.1 surround sound ports… Next, on the PC you often require a power cable and a Wi-Fi dongle connecting the devices to your home network! Like with USB 2.0, you can link together up to 127 peripherals at once via WUSB.

Displaying 720p audio and video content at home
Wireless peripheral connections aren’t just limited to the computing world, as wireless USB allows you to transmit audio to a stereo system as well as display photos or HD videos on a television with an Ethernet port via the DLNA technology, or on a digital picture frame or video projector. The interest in this is, once again, that no cables are required! The user is able to view HD streams (1280×720 (720p), 1440×1050, 1680×1050) from their computer directly on their television or projector, but unfortunately this isn’t possible in Full HD (1920 ×1 080).

Secure data exchanges with AES 128 bit encryption
We of course can not talk about wireless data transmissions without raising the question of security. Data access on WUSB is encrypted by the AES-128 CCM algorithm. In practice, the host attributes a unique encryption key to each device (camera, printer, etc) to be connected, with the connection then being created between the device and the computer by the user entering the peripherals code (a similar procedure to Bluetooth pairing). With the range only being 10 meters though, security is less an important element then on Wi-Fi connections, for example, where the range is a lot greater, increasing the risk of possible intrusion.
